"The Hum" is a generic name for a common class of phenomena consisting of a persistent, invasive low-frequency sound from an unknown source. In addition, the phenomena is only audible to certain people, existing at the far low end of the audio spectrum, with a peak power spectral density between about 10 and 60 Hz. The Hum is generally difficult to pick with microphones, though it has been on many occasions, and its source is difficult to localize. There has been some limited scientific research into The Hum, and its existence is well accepted. It is said to be heard loudest at night, and can cause great distress among "Hum sufferers."

Some locations that have reported this noise include Bristol, England, the Big Island of Hawaii (where its source is thought to be subterranean volcanic activity), the North Shore area of Auckland, in Taos, New Mexico, and several other locations. A specific Hum is usually named after the area where it is heard, i.e., the "Taos Hum" or the "Auckland Hum." The sound of The Hum is often described as that of a idling diesel engine in the distance, even though no such engine can ever be found. It may be audible in two locations dozens of miles apart, but usually it is localized in a relatively small area.

Various explanations have been advanced for The Hum. In at least two locations, a mysterious, persistent low-frequency hum has been investigated and then attributed to a known source: in Kokomo, India, where the sound was traced to a cooling tower emitting a 36 Hz tone and an air compressor intake emitting a 10 Hz tone, and on the Big Island of Hawaii, where a tone was attributed to known volcanic activity. On the Big Island, the native islanders point out the sound is more easily heard by men, which makes sense, considering that the larger the animal, the more attuned it is to lower frequencies, and men are known to be able to hear lower frequency sounds than women.

Regardless of a few instances where this noise has been explained, more often than not the source remains unknown even after significant investigation. Once the obvious sources of sound (traffic, household appliances, etc.) are eliminated, more exotic potential causes are often forwarded, including sounds from distant industrial sources, infrasound from geologic events, a microwave auditory effect from industrial pulsed microwaves emitters, tinnitus (a constant ringing in the ears), spontaneous otoacoustic emissions (a subtle noise emitted by the human ear itself), and, more speculatively, ionospheric heating projects like HAARP in Alaska.

I am very surprised that no one is talking about these particle accelerators buried deep within the earth. Could it be , that is why no one can locate the source? What about this "natural" magnetic pole shift going on, hmmmm...

We live west of Houston, TX. We have been hearing this same hum/vibration for over two years now! So frustrating! I've tried everything I can think of. Sound machines help us deal with it.

Posting from Granby, Connecticut here: If anyone else from the area is experiencing this, please do chime in!

I began hearing the humming noises maybe this Summer of 2017, possibly the Spring. Here it is, almost 2 a.m., and in full swing. It's quite annoying, and I wonder if I'd be able to fall asleep without taking sleep aids.

It usually starts about maybe 11 p.m. or midnight, but I can't recall ever hearing it after, say, 5 a.m.

At first, I thought it was just someone driving around, blasting bass-heavy music in their car. Now, I have zero idea what it could be.

Issues with the wood stove/ chimney? Can one even "close the flue", if one's wood stove piping goes through the chimney (I'm not referring to flue inside the wood stove, which is easy to close, of course).

Smart Meter issue? (I don't yet know if we have a Smart Meter.)

Issues with the power lines (above ground, of course)?

Transformer issue? There is a transformer maybe 2-300 feet from the house.

Weather issues? It has been raining on and off today, there is 100 percent humidity, and 6mph S wind.

All commercial buildings are at least a mile away, and we're not talking major factories - we're talking grocery stores, and a large gym.

By anon997358 — On Dec 23, 2016

There has been no hum today. Hope all you guys out there have a silent day too. We should mark the silent days to help with the search for the source.

I do like this day and its silence.

I hesitated to post here since there are so many posts already, but I saw someone from Denver and had to throw in my two cents. I live in Lodo (that's lower downtown to those not from the area) in a senior hi-rise. Lots of noise of course. The past few days, however, there has been a low pitched drone so insistent, so annoying and so loud that I have had to turn up my TV pretty loud to hear it over this noise. It sounds like a large generator or something. It is constant. It is relentless. And to top it off, it gets loudest when I lay my head down on my bed, plus my bed is actually vibrating from it! I initially thought it was due to the heat being turned on in the building for the coming winter but upon going outside to listen it seems to be coming from somewhere within a two block area where I live. Then again, it could be sound distortion due to all the buildings here. All I know is if I can't get this resolved soon they will find my body hanging from the shower curtain rod!

I live near Milan, Italy, Europe. I've been hearing the hum since October 2011. I paid attention during the rare outages that occurred, but the sound kept going. I hate earplugs, but fortunately I hear the hum only through my left ear, so I can put just one earplug to reduce the sound. I noticed that wax earplugs (the round pink ones) are the most effective, compared to the spongy ones that do not work well.

I noticed a recent change in the hum. It's been for years like two notes (one sharper and one more blunt) in a quite regular alternance, but in the last few months the higher pitch plays way longer than the lower. For those who still think it's their neighbor, please take a look at a website that's run by a doctor who hears the hum as well (so he knows what he's talking about). It's not a well functioning website but it is the most serious and genuine stuff I've ever found over the internet about the hum.

If someone has noticed the same change I have in the alternance of the two sounds of the hum, please let me know.

I live in Kent (UK) and have been hearing this annoying hum for about 3 weeks max. My hubby cannot hear it, initially I thought it may be my medication, but this has not changed for well over a 18 months. We have relocated to another part of Kent, the 'hum' was not apparent for the first 5 or so months, then all of a sudden there it was. I had my poor hubby checking all the appliances, even sending him up into the loft to check. Finding this post is encouraging as I now know I'm not going mad. The hum is constant, evident even when I remove my hearing aid. Yes I am quite deaf (not selective hearing as hubby sometimes insists), and the Hum is annoying. I hear it as a two stoke humming annoyance. The TV and radio do not block this incessant hum, well that is expected really, as I already said -- I hear it when my hearing aids are out.

By Tampapt — On Aug 13, 2015

I've heard this sound for almost two years now, I asked my older neighbor if he can hear and it had no idea. I explained to him the weird humming sound that was so annoying and that it could be from someone sending low frequency sound to my house or pipes under ground from the aqueducts. I think he thought I was crazy and asked me who would do that? I said someone who knows about electronics.

Time passed and now, almost two years later I ran into this website and see that many people can hear the same noise. The noise is very annoying and pulsates when the TV is on because some of the sounds from TV block it every so often, but that makes it even more annoying because it is in and out like pounding my head with a sound hammer.

Right now, I still have no idea what it is. I know it is not the pipes under ground, or anyone sending a low frequency sound to bother me. It's something else, perhaps worse, because it is all over the world and it's not some dude down the street with a device just doing it to me, in which case I could just move and get it over with.

I've heard the same hum miles away north and south at my mother's house. People need to figure out what this humming noise is. If it gets any worse, things could get ugly for the people who hear it, since it's already pretty bad.

Could it be satellite signals that make our electronics device function, like cell phones, GPS, and all others? I wonder if Stephen Hawkins can hear it and if he has any ideas what it can be? Either way, people have to send emails to the government agencies to figure out the cause because it's getting pretty bad and many millions of people have no idea what that annoying noise is. They think it is someone's AC unit or a generator far away but it's not. The people who can hear it have to help!

I have been experiencing a low frequency hum in my home and at night I can also hear it outside. Of course none of my neighbors can hear it. I live near, ~1 mile, a pipeline compressor station and can hear the noise out side if I walk along the pipeline even 2 miles from compressor station. I can pick up the sound in my house with a sound spectrum analyzer app on my iPhone and it shows on that device 24/7 even during power outages. Gee, just about how often a compressor station runs with its own generator backup. The frequency peak doesn't show in even the quietest areas away from my residence.

I don't think it is HAARP, or the smart-grid, or some mysterious electromagnetic phenomena.

Look for a pipeline compressor station in your area and you will find the source of the noise. Realize low frequency sound can travel for miles and can be very disturbing even though it may be barely audible.

It's a harassment device employed against those who have a clearer sense of what's going on in the world - those who are less bound to the materialistic, media-fed world of pablum. Individuals who might be a threat are targeted. If you hear this hum, either move, or get everything you can in its path to block it.

The hum will be coming from a nearby neighbor - guaranteed. This person is luciferian (a servant of satan) and simply targets whomever they are asked to without question. They use a low pitch frequency emitting device which does great harm to the human body, interferes with sleep, and disrupts concentration, to neutralize you as a threat to their new dawn luciferian order. It doesn't matter if you are actually a threat, but your thought processes worry the elite running things, for whatever reason, and you have been targeted to prevent you from becoming an 'actual' threat.

Update: The hum has now been for 1 year straight in North West Las Vegas. A low frequency bass hum that no one knows where it is coming from. When it is overcast or raining it is at it's loudest & pulsates. It never stops. It get's lower then louder between 11:PM and 7:am it goes right through my head. In the afternoon it is there as well. It is an inhumane way to live life in my once peaceful nice house. The EPA is all about taking tax payer money and doing nothing but handing out fines. I contacted them now seven times, and they responded by sending me 11 Google online links to forums about the Hum, pathetic. All utility companies have heard it, but do nothing to find it's source. Even the cable company came out on an unrelated issue, and he said "Man I hear it, I do not know how you can stand this."

By anon986671 — On Jan 27, 2015

Okay so we all [on this page] hear the hum. But what can we do about it?

If it's the grid and sun spots how do we stop that? And, why has no one mentioned their dogs?

My dog sleeps with me in my bedroom, which is the worst room in the house (an upstairs bedroom), and she seems to be frightened. I don't know how else to say it. It's that look that dogs get in their eyes when there's a thunderstorm coming and they're afraid. I have only read one mention of dogs and it was connected with the sound of thunder, only the lady said there wasn't any at that time -- just the hum.

And, hardly anyone mentions the physical side effects. Maybe not everyone is affected. I am. My body hurts. One thing, of course, is the lack of sleep! The other thing is I can feel this noise vibrating through me. Both the dog and I are having bladder problems.

I'm in West Tennessee, and as I live in a small town, I'm afraid to talk about this because people will think I'm nuts.

But, I did overhear two sales clerks at the local Walmart talking: "and it woke me up at 1:30 and 3:30 and I went outside and looked but couldn't find a thing." Seems like maybe I'm not alone here?

P.S. To the guy who was going to cover his roof turbine: Don't bother, it won't help.

The hum is here in Marietta, Ga. I only hear it in the house, never outside. The electrical power went off in my area this morning and I could still hear the hum.

By anon984115 — On Jan 05, 2015

I hear the humming in Dallas, TX. I have been hearing it for a few years now as well. We hear it best at night when it is the quietest in the home or room you are in. As a low frequency, it will travel though almost anything. It typically depends on the acoustics of the room you are in. in some rooms it is real bad in others virtually undetectable. It seems to be the loudest during evening hours. It can be heard outside as well when the surrounding background noise (cars, trains, planes, wind and pets) subsides into the evening hours.

I have used a frequency spectrum analyzer to isolate the audible frequency we hear. It seems to oscillate between 90 to 140hz (near sub-base level) with harmonic frequencies.

And for those of you who do hear it, does it sound like a boring machine underneath you about a mile away? A low rumbling that surges? Sometimes gets real loud and sometimes not detectable at all? I know, driving me nuts too. It almost does sound like it is from something industrial like a generator, industrial rock crusher or vibrating equipment off in the distance. When I started reading some of these posts, what came to mind was when I still heard it after a severe thunderstorm and everyone within a mile of me had no power and I still heard it. In fact, it was even worse.

I work in the power utility industry, so I know this is not a power grid generated noise. The closest it would come to this would be the armature of a power generator that is out of balance.

Good luck and happy hunting.

I'm in Las Vegas in the North West Shadow Hills area, and the hum has now been constant for 11 months, and it is driving me crazy, I cannot get any sleep. My neighbors says they hear something, but it is in my home 24/7 and never stops. It is in the air; I cannot hear it in the walls of the home, and it sometimes pulsates. It's a low frequency bass hum. When I'm watching TV, when they stop talking the hum is there. When I back into my garage, inside my vehicle, the hum is there. I had NV Energy out to inspect but they think we are crazy.

I've contacted senators, the EPA, The City Of Las Vegas, all couldn't care less. My quality of life is dramatically been affected. It comes through my bed, and ear plugs do not help as the bass hum supersedes everything. We are entitled to peace in our homes. This is a violation and inhumane.

You are experiencing smart grid syndrome. We all are connected to the power lines. The utilities are using power line communication to manage the mesh layer of the smart grid.

Whether it is a wired or wireless meter we are all interconnected via the power lines. This is why it is being heard world-wide. It is the cause of the modern day hum. Historically, the isolated cases of the hum were in some way related to the power grid and were electromagnetic in nature causing the acoustic and electromagnetic radiation to leak in the air.

The environments vary and the density of the radiation varies depending on population. What is constant and remains the common denominator that we all share is the grid. This is consistent with the timeline and the roll out of the smart grid network. It doesn't matter if there is a meter on your home or not that is transmitting two ways. The noise is in the air and is ubiquitous.

We have forensic evidence identifying the frequencies, which are illegal pure tones. The pure tones are single frequencies. That is why it is so torturous. It is the type of noise that is a health hazard because it affects our biology.

I recently began hearing the "booming/hum" sound inside my home. The first few months I thought It was just some high school kid booming his car stereo somewhere around my house being I live two blocks away from a high school, but in 15 years I have never noticed this strange sound. I tried to pin point where it was coming from outside but I could hear nothing? So then I figured it was just my central air unit in the garage. Nope, not. I then unplugged the surround system connected to the living room TV, thinking it might be the sub-woofer. The sound isn't consistent. It comes and goes but the worst is when I wake up to use the bathroom in the middle of the night and then can't go back to sleep because I can hear it again.

I've read some of the first comments here and some say it's the smart meter, but I don't use a smart meter on my home. Tomorrow I'm going to try and cover the air-turbines on my roof that keep the attic cool in the summer. However, I doubt that'll work. They weren't moving this afternoon when I heard the noise. Have to try everything before I label myself as crazy, or check in with my doctor to test my ears for tinnitus. Best of luck to everyone else having the same issue.

By anon971972 — On Oct 01, 2014

Smart meters cause this phenomenon. I made the power company remove mine off my house and it stopped in Georgia where I live, though at the time they would not replace them with analogs. Now they do, except you must pay $20 extra every month. It's a pure scam when it's obvious the smart meters are causing it. Also, HAARP and other atmospheric heaters will absolutely cause this phenomenon. Either way, you have your federal government to blame and they are 100 percent responsible.

By anon967807 — On Aug 29, 2014

Whittier, CA resident here. You can count me in on this mysterious low-frequency hum. Initially the droning sound woke me up, but increasingly the opposite occurs. For many years, I have used an air purifier at night as a means of masking sound, and whereas this low frequency hum initially awoke me, it now adds to the effect. If I don't set an alarm, I will sleep 12 hours, thanks to the constancy of this droning noise!

About three years ago I developed tinnitus in my left ear, which consists of a 24/7 mild but high-pitched noise that is a completely distinct from this low-frequency hum. I underwent a brain MRI and neurological consult a year ago, and no cause was found. The time period during which my tinnitus developed correlates with when Smart Meters appeared in my community.

I never drew any connection until I went out of town and noticed that my tinnitus was gone. The only difference was that the mountain community I visited had not undergone the smart meter rollout. That's when I drew the connection between smart meters and tinnitus. It wasn't until after I observed this that I thought to research the issue and found that other people have had the same experience. My spouse, during this same period, has lost portions of his hearing. We do not have a hobby or occupation that could account for adverse changes in our hearing these past three years, nor are we "elderly" by which to expect as much.

In addition to the smart meter rollout, fracking and oil exploration began near my home a couple years ago. These are the only significant changes, short of blaming it on the usual seismic suspects. My next best guess would be the hastening drift of magnetic North. Magnetic North has been shifting faster in recent years, and perhaps this phenomena can account for why this "hum" is heard in so many parts of the world. On the other hand, wi-fi, bluetooth, cell towers and smart meters have also saturated much of the developed world in recent years. Perhaps the effects as this wireless infrastructure build-out are additive?

Periodically this summer, I have heard a thunder-like variation on the sound, not unlike a heavy equipment truck passing in the distance. On two occasions the noise was loud enough to bring me out of the house to look around for the source of the noise. I have been unable to localize the source. When this variation occurs, the neighborhood dogs begin barking from a variety of streets/directions. When I step outside to see what the ruckus is about, a rumbling noise can be heard in the background (on days no thunderstorms are expected and no thunderheads are visible even at a distance). This has occurred several times early this summer, typically in the early afternoon, and persists longer than would be expected if a heavy equipment truck were passing.

Most commonly, however, I hear a faint, persistent droning sound that neither increases or decreases in pitch. It sounds like a diesel truck idling in the distance but manages to penetrate walls, earplugs, etc., and is not possible to isolate. What I am hearing is near the lower end of the audible spectrum. Some people I talk to can hear it, others cannot. (There were two early morning incidents little over a year ago when the droning sound became loud enough for my spouse to hear, but otherwise it is distant, albeit steady, and noticing it at all is very much a function of how good one's hearing is.)

As a birdwatcher, I am concerned that this low-frequency sound may be having an adverse impact on bird populations. Since mid July, birds that have been in my area for years have either left or gone into hiding. A noisy flock of Red Crowned Parrots have flown over my house regularly enough to set a watch by, morning and dusk respectively for the better part of 10 years, yet this year their flight pattern abruptly changed and the majority are gone. Today, if I see Red Crowned Parrots at all, there are fewer than 25 compared to 60-plus in the past. At dusk, they circle around randomly, moving from tree to tree, until it becomes too dark to fly. This confused behavior is now typical. Other bird populations that have favored feeding, perching, roosting and calling spots have also disappeared or gone silent

I have observed the periodic activity of local hawks/raptors in that they temporarily scare off birds from feeding and perching areas. What I have not seen in all my years in this area is birds go silent for weeks on end, beginning during the height of breeding season. The last time the area was this quiet was when the West Nile virus swept through, after which it took several years to witness a full recovery of native bird populations. I can't prove causation but I do know that the frequency with which I hear this noise correlates with the nosedive in birds of all species in the area, which dropped off sharply in July. It has become unusually quiet even at sunrise and dusk when birds are generally more active. I haven't heard any reports of West Nile die-offs this summer to account for this.

If this low frequency hum is industrial in nature, I wonder if the environmental impact reports for gas and oil exploration account for displacement of wild bird populations? Scientists are just beginning to appreciate that birds are capable, much like elephants and whales, of navigating via infrasound. If this is industrially-generated, the impact must be studied. Then, again, understanding that certain types of testing interrupted communication between dolphins and whales hasn't stopped the Navy from utilizing controversial technology undersea. I have to wonder if there is a land-based equivalent — newer than HARP — that can explain this.

I live in northern Vermont and have noticed a deep, droning sound every now and then for about four years that would last a few hours every night and then disappear.

Since last week, however, it's been pretty much 24/7 and has been getting so loud that I wake up from the noise. It's like many others have described: a somewhat low rumbling, droning kind of sound, feels as if I'm standing next to a loudspeaker when deep bass music is played. The vibration hurts my ears and gives me headaches. The noise is outside and inside, no room is exempt. The noise is audible in the entire neighborhood - I've checked.

I've talked to some neighbors who don't hear it. My husband, who has severe tinnitus, cannot hear it either. I've called the Air National Guard and asked about exercises during the night and was told they don't conduct them at night. I called the town and local police, but found out nothing. f anyone here in VT has a similar complaint, please post. I need to get to the bottom of this! Thanks!

Got yo hum all right. It's polyphonic, like a duplex coded warble in the microwave auditory range of upper register (like on a piano), like maybe an octave above middle C. It plays a phase shift modulation at the 5th interval, and a dissonant jam. It seems influenced by conscientious thought pattern frustration, like you're stepping on its normal routine if you put the brakes on your cognitive processes. It must be mind reading by remote control made simple as an old analog broadcast TV signal--and that's possibly how all of us were burnt for it like PROMs.

There are all kinds of tonal depth and independent source in the spectrum of the aural background there in the dead silence, actually. My thinking it is a bigger problem than we could imagine, but it does involve our betrothal to technology, however ancient. I think it involves a larger neighborhood and its control policies.

Live long and prosper, and try to forget about it. It does subside with enough low level background noise, like a TV that's always on showing reruns. Now I think I can figure out why my neighbor freaks in adjoining apartments abuse their sound equipment so much. I guess that's practical empathy.

By anon954574 — On Jun 02, 2014

I hear the hum sometimes at night in my home in Berlin, Germany, as well as in other parts of Berlin. My mother and I have also heard the same humming noise in her house (and she states also having heard light earthquakes before they actually happen) so at least I can rule out some sort of hearing problem in my case.

By anon954463 — On Jun 01, 2014

I'm in coastal southern Rhode Island and hear it some nights, always between 11 p.m. and 6 a.m. It wakes me up and keeps me up, as well as my son. It isn't rhythmic enough to ignore, it has random increases/decreases in volume and speed of vibration.

Last year, I assumed it was my neighbor's bass music or truck idling until one night I drove to find it and couldn't pin it down. It's awful. I've had many sleepless nights and time spent wandering the yard in pajamas. Not even a white noise machine drowns it out due to its odd frequency.

I live in South Yorkshire, UK and I started hearing this "hum" like a bus or truck parked outside nearby about 12 months ago. I only hear it through my right ear and its driving me mad. As others have mentioned if I turn the TV on or radio, it masks the sound and I get some relief. Today I traveled to the coast for the day and while there the humming disappeared about 20 miles from home it returned and at home i am hearing it now. Last year I went to the south coast for a week and again completely gone until I got back in South Yorkshire.

By anon953117 — On May 24, 2014

I hear this noise, a low droning sound, like a distant motor. The oscillation is short waves, the variation in pitch is tight from high to low. I would not be able to approximate the Hz cycle, but it is low. Sometimes its louder, but always present, at least for the past few days. Has anyone experienced any physical effects? Lack of concentration, fatigue, depression or sinus pressure?

By anon952756 — On May 22, 2014

I am so relieved other people hear this. I have been hearing it since December 2013. I lived in Oshawa, ON then. My husband couldn't hear it and then we lost power due to an ice storm for two days and I could still hear it. It's constant for me, 24/7.

The only time I don't hear it is if I'm not "tuning" into it (having background noise helps). We moved to Northern BC and I still hear it here. I don't gets headaches or feel sick from it though. It just drives me nuts!

By anon951609 — On May 16, 2014

I hear it too. It has been ruining my life for the last six months. My family does not hear it, but when it is very loud it makes them sick anyway. I get dizzy and have stomach aches, anxiety and panic attacks. The timing could not be more perfect if it were choreographed.

We live in Maryland, USA. I barely sleep anymore because it is loudest in my bedroom and audible everywhere in the house. We also have smart meters and live shockingly close to a brand new high pressure gas line, though I cannot say that is the cause, because the timing is off.

I have heard the hum. I have a background in computer programming and have logically tested items in my apartment and the building in general and have come to the conclusion that it is either me producing this or something is directed at me.

It actually happened at a different location miles from my apartment where I first experienced it. It is no longer waking me up and keeping me from sleeping. Very weird.

We have had a constant hum in northwest Las Vegas for four months now, along the Gilmore Flood Channel in Shadow Hills.

On Easter, we hiked near the top of Mount Charleston and could hear the exact hum. It's a low frequency harmonic bass tone that never stops. I had NV Energy and South West Gas come out. They all heard the hum but could not identify where it was coming from.

I contacted the City of Las Vegas code enforcement and the EPA, Neither could have couldn't care less. Our tax dollars "not" at work. I have not had a full night sleep in over four months when this bass hum started.

I'm in Oakville, Connecticut, USA. It is the high pressure natural gas lines. On a business trip, I have listened and heard it occurring near Guelph just off 401.

I believe it's like some of the movies suggest. Aliens are either transmitting some types of commands only for certain people to help assist them in something in future. Maybe perhaps like the war of the worlds movie. They have their space ships running underneath the earth's surface. Just a guess. Good luck though, and remain calm. A fellow hearer.

I live in Oakville, Ontario, Canada and have been hearing a rumble since a couple of days ago (march 2014). It is constant with subtle variances every two or three seconds. Is more pronounced at night and is very difficult to pinpoint the location from is coming. I live 50 meters from an underground gas pipeline and it is the only source I can think of. Now, I have lived here for six years and this is the first time I've heard it. Nobody else at my home can feel the sound. I'm trying to locate more people who are impacted or are hearing it as well.

I'm San Jose, CA. We have had the hum driving us nuts for about five months. We thought it was construction on the Stevens Creek / 17 / 880 intersection. I would walk over there and sure enough, they were working with their equipment and cranes, etc. We got the hum pretty loud tonight after missing a couple nights' sleep (and days) and walked over again, but it was completely closed for the night - nobody working, not even the generators that are sometimes kept alive in the early hours.

Another poster mentioned to close the flue in the chimney and I just did. Holy cow! It is almost gone! No rhythmic droning, just a low purr more quiet than my computer. I've been up for 36 hours until now, and now feel like I can sleep.

I've been sleeping maybe three days a week with some regularity for the past several months, but prior to that I always slept well. But what has changed? We've closed our flue before, for months on end, and had it open for even years on end without this noise. Walking around the house and comparing it with the air and ground traffic, it seems to follow a pattern, the humming rhythm and ambient traffic. Perhaps it's a harmonic that hits houses somehow. But why now and not all our lives? We're around 50 and this is new.

I started hearing the hum in Las Vegas a night ago. I'm hearing it right now at 3:58 a.m.

By anon935037 — On Feb 23, 2014

For those of you who think you can end the annoyance of the hum by moving, I feel you are wrong. I feel certain people are just more attuned to it than others. For instance, I have heard it and my husband does not.

By anon935035 — On Feb 23, 2014

I heard this humming noise the other night for the first time. It woke me from a sound sleep. It just so happened that we were about to have a strong weather event. But not an earthquake just some strong storms with thunder and lightning. My husband could not hear it at all. It seemed to be coming up from under my bed. We live in a mobile home which is less than three feet above the ground. After the storm passed, the humming went away.

By anon933450 — On Feb 15, 2014

We have been suffering from sleep disruption for 2 years now and it has been slowly getting worse. We live in Newport, Shropshire, UK. At first we thought that our neighbours, who were away on holiday, had left something running in their house (we live in a detached bungalow).

However, we are sure that the noise is being generated by an anaerobic digester that is about 0.5 miles away from our house. Our neighbor has also complained about the noise. The Environment Agency has been involved and says that the noise is at an acceptable level. But, as I type this, we have been awake nearly all night!

If the weather is still and there is little wind, the noise can be heard outside, although it seems magnified in the house and when I have my head on the pillow, the noise seems to be coming through the bed and pillow. As others have said, it sounds like a truck running outside the house.

We are at our wits' end, now. We have spent two years renovating our house and it is now nearly finished, but if we could, we would sell the house tomorrow and move somewhere else. The only time I get a good night's sleep is when I go to my daughter's house and she lives on a busy main road!

By anon933193 — On Feb 14, 2014

Oh, sorry. Location of post 135: Baton Rouge, Louisiana,USA

And yes, we are surrounded by heavy industry. The closest installation is about five miles away. The KC Southern railroad tracks are also a couple miles away. I-10 is a few hundred feet away. I know what all that sounds like. Heard it for years. This is not that.

By anon933183 — On Feb 14, 2014

Update to post 135. I've located at least two sources for the mystery rumbling:

Thumping bass notes from the sound system of a bar about an eighth to a quarter mile away, as the crow flies, or thumping bass notes from our next door neighbor's car stereo, and possibly, a home stereo.

Sometimes it's one, sometimes the other, and sometimes, both. When it's both, I think that's when it sounds most like the dieseling engine of a faraway locomotive, stopped on the tracks. I would actually have sworn that's what it was, except nobody runs a train engine for two or three hours without moving it on down the tracks.

At times, whoever is in charge of the volume turns it up very loud, but usually just for a few seconds, and rarely, for a few minutes. At that point, it has rattled the windows and knocked change off the dresser. It would do little good to call police, because by the time they arrived, the noise at that level would be long gone.

Except when it's maximum loud as described above, I also hear it only inside the house, and mostly, in only one room -- our bedroom. It is louder when reclining on our bed than sitting on it, and least loud when standing in the room. Sometimes we can also hear it coming from the fireplace in the living room, and sometimes, it even rattles the windows in our living room. Our house is an old raised post-and-beam, with huge wooden double-hung windows. It seems to be acting like some sort of receptacle or receiver for this pulsating vibration, kind of like a musical instrument or a drum.

Oh, and it's not in my head or my ear, because when the electricity is off in our area (lots, lately, as our grid falls apart), it is blessedly quiet. Also, though this noise sometimes goes all night, it usually is quiet by about 2:30 or 3 a.m.

Also, when we go to our camp located in a very remote rural area with no close neighbors or even so much as a cell tower (we have to use a cell signal booster to make/receive calls there), there is absolutely no such rumbling, thumping, or bumping. The relief is blessed.

Also, our neighbors have been quieter with their music, after we complained to the property owner. I have been considering mounting a boat air horn at the edge of the property, however, and blasting them whenever I feel disturbed by their music. It would be worth getting a citation or two from the police.

I think the confusing thing for me was two stationary sources of rumble, combined with the occasional passing rumble of cars on the roads. Oh -- and the nature of this sound is so low-pitched, that the source is quite difficult to locate.

The recent proliferation of these thumping, rumbling "earthquake bass" music sound systems in vehicles and night clubs is the main source of this "hum", in my opinion. They are so common now in a large city, the rumble from dozens of "boom cars" at any one time must be unbearable.

Sometimes, while stuck in traffic waiting at a stop light, or getting gasoline at a station, I’ll hear someone play one of those things so loud that it rattles the windows and feels like they are thumping me in the sternum. It feels like a physical attack, one you don't know exactly where it’s coming from, or how to get away from it, or make it stop. Once at a long red light, I just laid on the car horn until it stopped. Others did the same, repeatedly, and the person finally got the message and cut it out.

I plan on pushing my lawmakers and representatives to address this source of extreme aggravation.

By anon932367 — On Feb 12, 2014

We have this hum around Ottery St Mary. We have investigated everything and the electricity board recorded it for us. Several businesses have turned off large devices including an archimedian screw on the River Otter. Not one of them was the cause. We have now exhausted the potential causes. It is either a large generator or a large pump according to noise experts, but who is running it?

By anon929506 — On Feb 01, 2014

This is coming from the drones in the sky. They are cameras emitting electromagnetic waves. These things make that kind of noise and vibrate. They are hovering in the sky and you are a target. They are so strong. It is taking video inside your home through your walls and windows. If you have metal in your body, it is worse.

They have used some type of lasers in my house and have broken plastic. They turn on motion detector lights and the TV, they mess with electronics, my whole house vibrates like there is an earthquake and I'm in Ohio. Look up. Those are not all stars!

By anon928557 — On Jan 28, 2014

Has anyone experienced this in New York City? I moved from an apartment in Carroll Gardens, Brooklyn, because I heard a low bass hum and felt vibrations at night, as if a truck were idling outside my window. I'm having the same experience in my new apartment on the Upper West Side, although it is much fainter.

By anon924974 — On Jan 08, 2014

I lived in the Redwoods with a few houses around. For years, I heard the hum. I thought for sure somebody had a generator underground. That's what it sounded like. I moved 300 miles away to Lake Tahoe and I hear the hum here: the same muffled engine running sound!

By anon359989 — On Dec 22, 2013

I live in West Rogers Park, far north side of Chicago. I've been suffering with this Hum since around March of 2003. It’s usually worse around the change of seasons, but this year is different. It’s horrible, horrible now, December 2013.

People's Gas has installed new 'high pressure' gas lines all over the Rogers Park area very recently, supposedly to facilitate newer fixtures without requiring boosters. Many cell towers and SmartGrids are now installed in the area as well. Also, we’re very close to Deep Channel, and heaven knows what they are doing down there.

I hear it in other homes on my block. It is worse on our second floor (bedroom floor) then on the first floor. It’s like a low note pipe organ going off in your head, rousing you from a deep sleep. Others have suggested it's either high water pressure from the mains, or high gas pressure. I’m currently investigating both. I can say for certain it is not toilet valves, attic fans, or T&P valves from hot water tanks as has been suggested by others online. It’s awful.

I plan on launching an awareness campaign to see who else is being affected by this noise atrocity. And, yes, I have had my hearing checked, just to be sure.

By Sandaura — On Dec 22, 2013

We have forensic evidence of both power quality and octave band sound measurements pointing to the smart grid network as being the source. Thousands of people are becoming aware of the noise when the wireless metering is turned on in their areas. The global grid is pretty much ubiquitous. Please join our network and fight to stop this public health hazard now.

By anon359487 — On Dec 18, 2013

For about a year and a half, I have heard a low rumble that sounds -- or more accurately, "feels" -- like distant thunder. My husband can barely detect it, and it doesn't bother him. It bothers me. I feel it like a thumping in my chest. It's most evident usually at night, and when I'm in certain parts of the house.

When outside the house especially during the day, I usually can't detect it at all. At times it keeps me up and I lose sleep. I have assumed that it is the bass and percussive notes from one of those sub-woofer "boom" stereo systems that can be put into automobiles and home entertainment systems. I've even called police, thinking it was the next door neighbors. (Police couldn't hear it) The neighbors have, in fact, played booming music late at night, but lately, this particular noise sounds more regular and machine-like than a beat for any kind of music. It often goes on all night long and into the next day, with little or no break, as between song tracks on a CD. Usually it's less noticeable during the day. At times, it completely disappears usually for hours. The relief is blessed!

I have even gotten up out of bed and driven the neighborhood, looking for the source. It's nearly impossible to detect outside my house, though. Best candidates so far: One of those large cooling-tower commercial air conditioners at a nearby corporate headquarters complex, an actively producing oil/gas well and storage facility about a mile away, and finally, the bass register of the neighbors' booming stereo, maybe turned down low and set on auto.

It is very similar to a low rumbling I've heard coming from the Exxon Refinery about five miles away, but that rumbling is much louder, and lasts only a few seconds or minutes at a time. It also is accompanied (usually) by a hissing sound.

If it were airplanes or traffic on the interstate, it wouldn't sound so machine-like and regular. Suggestions?

By anon358813 — On Dec 13, 2013

I live in north Florida near Camp Blanding -- a very active National Guard base. For over a year I have heard a constant droning sound. Just within the past few months, the sound seems to have changed a bit. It is less intense yet similar. To me, it seems to be oscillating vibrations from underground and I thought it was our well pump. However, I have heard the sound during power outages.

My husband, who does not hear it as I do, suggested that it might be a generator. My theory is more associated with the military installations nearby. Still, I do not know and would really like more clues. I am glad to "hear" that I'm not alone in this. It seems to be a worldwide issue. I just hope this is a force for good. We must be the gatekeepers of sound. Let's keep ourselves informed.

By anon358663 — On Dec 11, 2013

Phew! I thought I was insane for hearing this. I hear a low humming noise like a big rig parked outside my house and it lasts for hours. Usually, I just go to sleep and ignore it.

I've been hearing this for the better part of a year almost every night (only at night -- never in day time). I'm not much for conspiracies, but what the hell is going on? I just recently noticed an online presence of people talking about this and I'm relieved that there’s some recognition outside of my own head. By the way, I live in central NY and I can hear it now as I type this.

By anon354714 — On Nov 10, 2013

I live in Quebec City, and have been hearing this hum too, for the past couple of months.

It is an oscillating low frequency hum. I used to do mastering in studios, so I have very developed ears. I can hear very low and very high. This is in the range of 40hz to 120hz. What's going on?

By anon353611 — On Oct 31, 2013

I'm in Tampa, Florida right now and started to hear this low frequency sound as I was going to bed about 11 pm. At first I thought it was a helicopter flying past, and then I realized it kept on humming and as a matter of fact, is still humming and it's 11:38 p.m. right now.

So I'm thinking it's the A/C, but the A/C is off. The washing machine isn't running either. It's kind of bothersome, this "humming". Makes me feel kind of weird, kind of like I'm out of it or something. I've had strange feelings like this before. but this is the first time I've actually heard the humming. It's so weird. It's the worst at night and throughout the night.

I'm sure it's not a truck or car or anything because when I hear one pass by or when one starts up I can tell it's a completely different sound, definitely not as low frequency as the "humming". Anyway, I wonder what it really is. I just want it to go away. Really stinks, no doubt.

By anon352300 — On Oct 21, 2013

I live in Kerry, SW Ireland. Since April 2011, I've heard a 24/7 low frequency pulse or vibration, far away from cell towers or cities. Check out the Beaufort Hum.

By anon349066 — On Sep 23, 2013

I have been looking for the hum, glad I am not the only one, thought I was going mad! It started around August 2013, in Nuneaton England, and I thought it could be health related, stress or depression. I also have acute hearing, I think.

I tried sleeping medication, which gets me three hours sleep, then I wake up, and hear "hum hum hum." The point is, am I totally going bonkers.

Like most, I've listened, switched off the power, thought it was the pump from fridge/freezer, but the sound doesn't match. I found one main vibration coming from chimney stack, so I thought perhaps the sound was vibrating though the chimney.

At this point, there is no sound outside, only inside the house, and I hear a vibration or low buzz. It got so bad I punched the wall. I think it could be affecting my REM sleep. My dreams are nightmares, and I have a migraine (pressure, tension headaches) and it feels like my head is about to explode. I checked my BP (blood pressure) and it was 138 over 105 and my heartbeat was 98, so I was stressed out over the noise, or have an underlying health problem causing me to hear the low, bass hum.

There's no other place to sleep. The living room feels like it's a wall of sound and pressure. The bedrooms vibrate, then hum with a low bass tone, repetitive, at a frequency intolerable to humans.

Does any one know if pest control sonic devices have been known to cause this sound?

By anon348322 — On Sep 16, 2013

I live in upstate New York. Every night, usually around 1 a.m to 2 a.m, I hear a weird, whirring, pulsating sound, very low in frequency. It seems to change in speed and then fade away. I first noticed it over a year ago, but I simply never paid it much attention until now. Even tough I thought it was strange, I just chalked it up to my laptop or hard drive oscillating and my table top reverberating. I recall several months ago I jokingly mentioned to my mom, "Do you ever hear that noise at night? It's like a damned UFO is hovering above the house, a very low whoom~whoom~whoom~whoom..." Of course she looked at me like a dog with one ear up, so I just laughed it off like I must be crazy.

So tonight when I heard it, I decided to investigate it. I put my ear to everything, and it's not my laptop, it's not the hard drive, and every time I hear it, I'm sitting pretty close to my open window. If I close my eyes and focus on the source of it, I can hear it is definitely emanating from outside; of that I am certain.

When I start hearing it, I can't un-hear it, if you know what I mean. I don't know, it just feels ominous, and puts me in a weird mood. If you've ever sat in a room with just a fan on (I've done this while reading) and the sound of the fan spinning/circular pattern eventually just makes you zone out almost trance-like, that's what it's like. The pulsating sound just kind of gets a hold of you and you forget; you're just in it. Only when I'm conscious of the sound do I feel unaffected by it, at which point that's all I'm thinking about anyway. It just comes and goes every night and what really bothers me is it seems to be on a schedule like. I don't know, doses, sessions, intentional. I feel like a paranoid freak just typing this out and reading it, but I swear on everything this is 100 percent true. If I'm lying, may God strike me with every misfortune imaginable and I swear it with no evasiveness of the mind. I hear a "whoom~whoom~whoom," and it's like it is aimed directly at me and I say this because if I go outside, I cannot hear it; I can only hear it from the upstairs level of our house where I sleep. How weird is that?!

By anon348032 — On Sep 12, 2013

I'm in Spokane, WA and have been here for about eight years. I'm so glad to hear other people have heard this noise. I started hearing the noise right after we moved into our new house. I really thought I was going nuts. Most of my symptoms have been repeated here in these posts several times: low frequency noises, mostly at night, heard out of my right ear. I also have to sleep with a fan on and my husband cannot hear it. I also feel the vibrations but he doesn't. No one I have asked has ever heard or felt it. The sound seems to be localized in my house. I have, however, heard it in a few other locations like Priest Lake, ID and Glacier Nat'l Park in Montana. Those were very brief though, so I thought I was just nuts.

From reading all these posts, I must agree with those that believe it is the microwave repeaters. That makes the most sense as this appears to be worldwide and cell phones and repeaters are pretty much everywhere, even in the country. We have one about two miles from here. I don't know what to do about it though. It's hard to "just live with it". Unfortunately I cannot afford to have any testing done to locate the source. I've done all the "process of elimination" things like turning off the power. Nothing worked. It is not the smart meter, either. They put one on our house several years after I started hearing the noise.

I just hope there's an answer soon, although I doubt it. I've been living with it for eight years now and I cannot afford to move. I hope that if enough people keep complaining about it, someone will figure it out and fix it. I'm just glad I'm not the only one and now my husband finally believes me.

By anon346057 — On Aug 25, 2013

I have trouble sleeping when my neighbor has his fan blowing into his apt but when he don't have it blowing I sleep like a rock. Could this be the Hum's doing? Can my neighbor's fan cause the hum noise and I'm hearing it which is causing me not to sleep?

By anon344921 — On Aug 14, 2013

This is an update from Lulu1958, Since May 2013, I have not heard the hum at all, but there is another sound. It sounds like a train coming up the tracks. This sound occurs every 15 to 30minutes. Unlike the hum, I do not hear it after 1 a.m.

Where I live, there is a train track about 200 yards away, but this sound is not the train.

By anon344709 — On Aug 11, 2013

It sounds like a train in the distance. I was awakened by the Hum last night. I went for a ride and looked down towards the railway tracks and a train was passing by. Does anyone else who has heard the Hum have trains within 3-5km? If so, check the timetable and you might know where the sound is coming from.

By anon343907 — On Aug 04, 2013

I live in North Sweden (Skellefteå). I've started noticing the hum and having more and fewer problems with it, depending on house, season and weather, for about nine years.

It got a little better when I moved 20km to the city. (From the third floor to the first floor), and I've heard it at one of two places I have worked at, and also at some friends’ houses.

First, I thought it was a new wind turbine 6km away, but I could sleep very well both this year and two years ago at my uncle’s house, which has nine wind turbines just 1-3km away.

When I have problems, I mostly have it a few days in a row and maxing out after 4 a.m., when it then wakes me. Perhaps there is more than one frequency. Right now, it’s like a sweeping pulse every three seconds, where I can feel the air pressure going up and down.

Sometimes it’s like a fan spinning faster and faster, up to 10hz or something, but the speed is randomly accelerating/decelerating (perhaps sometimes also constant, but I'm not sure, just as if it were a fan).

Another reason why I think the sound has many frequencies is that the room I am in seems to define where I feel it. In my computer room, I feel it a little more in my head, and in the living room I feel it more in my chest and stomach. Sometimes it feels like my eyeballs are vibrating.

I actually moved from my last apartment and to the city because of the problem. It was so severe that I had to try to sleep on the floor on the bathroom, which almost had no sound, but then in the night, the frequency had changed to it was also in there, but could then be better in another room. The toilet was at the end of a long hallway, so I think that is why it sometimes resonated on a very low frequency. It felt like a big hammer on my heart and internal organs.

I called someone to check for infrasound. They measured at daytime, and they said that their instrument did not measure below 20 or 30hz because its not possible to legally complain about lower frequencies than that. After measuring for five minutes, he said there was no noise, although he said that he could see the noise curve starting to increase the closer to 30hz it came, so he said it could be some kind of overtones and he could see a lower frequency noise, but he never left it to measure during the night either.

I found I was EMF sensitive around the same time I discovered I can hear this hum, and I also had an infection in my right ear and got tinnitus, hair loss and depression. My EMF sensitivity started with me feeling tired with working with computer monitors all day and all night, and then I also noticed I felt depressed when within one or two meters of fluorescent light. It felt like my eyebrows went down.

It takes me a few minutes before getting depressed when I am subjected to microwaves. I now have two field meters and I’m sensitive to around 1-25microwatt/m2, but I don’t want to bore you with that, but I also heard that many EMF sensitive people also are infrasound sensitive.

However, the times when I felt extra EMF sensitive I have have not had more problems with the hum. Perhaps the EMF is more coupled to how strong my nervous system is, and the hum sensitivity more dependent on season and temperature outside, etc.

Perhaps some foods increase sensitivity too, like nuts and lack of sleep and water, and too much or too little exercise.

Since I quit a stressful job two years ago, my depression has been gone. My EMF sensitivity is better too, and perhaps also my infrasound sensitivity.

But now all of a sudden, I can’t sleep for a few days except at daytime like some other person said. It helps to move to another room. Sleeping near my apartment door/lobby works best. I can’t hear the sound outside, I don’t think, but I could at my old house 20km away.

There I noticed that when I walked at a place where the road went very strongly downhill, the sound disappeared. It came back when I walked back to the top of the "hill/road" again.

Apart from the room acoustics/resonances making a difference, I also notice that that hum noise differs a little depending on how I place my doors. Big doors have the most impact, but I also can feel a little difference if I open all cabinet doors in my kitchen or closet. At some angles, they seem to dampen the noise a little or change the harmonics as if I were inside a flute.

I’ve noticed that when the infrasound hum is at its peak, I sometimes can see and feel my doors swaying a bit as if they were circulating in a wind draft going forward and backward.

I wish I could come up with something that could measure it. My uncle, who is an inventor, suggested a pen laser mounted on a door, but I’m not that practical.

I could also mention that arranging furniture in my house also made some difference, and having a round pallet for sitting on in the room helped too, but then again it could obviously not help enough. This apartment building is said to be have natural ventilation, i.e., no fans, but it does have a large chimney.

My last apartment with more problems was a few km from a big industry melting gold and the harbor, etc. There might be some super small bioconverting plant a kilometer or so from this house.

I can hear humming from the large bioconverting plant in my city from about 2.5km across the river and I can almost see the chimney from that range). But I live 6km from it.

I hope this can be of help to someone. Perhaps someone could make a web database of cities where the hum has been heard. I would myself. I know one does not exist. – Anders, Sweden. Going to try to sleep now. It’s 8 a.m.

I'm from northwest Canada. I was terribly affected by the Hum for about six months around the time of the Fukushima earthquake. I had been using a cordless phone for years, located next to my bed. Since I got rid of it, the Hum isn't so bad, but it hasn't completely disappeared though. I'm careful now to avoid wifi devices.

It appears that that the hum is primarily wifi microwave interacting with variations in the geomagnetic field. That would explain why the hum is worse at night and early morning for most people, when the geomagnetic field is more diffuse. Or for those who are in earthquake prone areas, such as New Zealand or America's Pacific coast. Some people are naturally more sensitive, but it looks like length of exposure to wifi microwaves also plays a role.

By anon343211 — On Jul 28, 2013

Concerning the Auckland, New Zealand hum.

I have been hearing the hum for the last couple of years.

It is here 24/7. I am the only one within my circle of family and friends who can hear it. My hearing is very good. When I put my fingers directly into my ear canal, I can get the low frequency humming noise from 100 percent down to about 20 percent.

I do believe that it has something to do with microwave technology and broadband over power lines and smart meter technology. It's something to do with the microwaves being converted into an actual acoustic sound. I am not an expert, just a hum sufferer like most of the people who posted a comment here. I feel like I want to escape to this hum free spot which I am still searching for. Has anybody found a hum free area by now?

I don't want to be negative, but if it is technology related, I doubt anything will be ever done about it, since this technology is big business. My heart goes out to all of the people who experience this.

I am losing sleep. The noise is continuous. It is louder in the early hours of the morning and quietens down during the day but is still loud. I have to keep the radio on during the day. I can't put it on all night because I would need it on too loud to drown out the droning. The council can't help. I can only hear it inside my house. I have had everything electrical tested and have been to the doctor and the hospital to have my ears tested. I am at my wits' end. The noise is making me ill. I live in Cheshire, UK.

I heard a hum for the first three or four months I lived in Atascadero, CA. It was so annoying! I would lie down to sleep at night and it sounded like construction work was being done in the distance or a truck idling. I tried plugging my ears and sleeping on different sides and even sitting up, but it wouldn't go away.

Since it never happened during the day, I just figured it was an inner ear issue/stress of moving that I just wasn't "tuned into" during daylight hours. I looked up tinnitus on the internet, but it didn't seem to fit my symptoms, and there was no treatment offered, so I lived with it. Eventually the hum stopped, thank goodness!

My daughter and I can hear this high pitched ringing most of the time, We live five minutes down the road from each other. We have noticed that it gets worse every time it clouds over.

I don't live near and factories or phone towers. I have even gone outside and can still hear it. Over the past few days, it has been very bad, and I am even getting a feeling of a slight pressure above my nose. I believe that someone is using some form of electricity over the UK and around the world, and this is what might be causing these health problems.

By anon340185 — On Jul 01, 2013

I have experienced the hum for the first time here in a northern suburb of Detroit. It was a low frequency vibration that I thought was a train engine idling in the distance. It only happens late in the evening when I go to bed.

The sound varies in intensity, starting out weak and then gradually escalating in intensity and vibration until it reaches a peak and then dissipates, but then repeats. It usually starts around midnight then continues through until morning.

By anon339564 — On Jun 24, 2013

I heard this about four days ago and thought it was next door with a generator or something or my own ears. It usually starts about 7 p.m. and then stops about midnight. I live in Ormskirk, Lancashire on a very busy road, but can still hear it over traffic. I only noticed it because I have been studying for my degree, so there are long periods of no internal sounds.

By anon338718 — On Jun 17, 2013

In Byron, GA, Crawford/Peach County area, there has been a month or so of constant, low, pulsating, bass sounds. The electricity went out the other night, so I know it is not my home. I went up the hill to the road and could hear it there too, and I need to check up and down the road and with neighbors to find out if they hear it. I had a roommate confirm he hears it to but not until I brought it to his attention. It "vibrates" in my ear bothering me. I wish it would stop.

By anon338108 — On Jun 10, 2013

I have been hearing a light humming noise here in Azilda, small town near Sudbury, Canada. This is a very quiet town. At times it sounds like a jet noise but constant, and I look in the sky and see nothing. This is a huge mining city so yes, that could be a possibility. Except I've been here all my life and never heard it. I don't care what it is. I just want to know.

By anon337096 — On Jun 03, 2013

@anon314602: I live near Rhinelander (Woodboro) and am also hearing the low frequency hum. I hear it most constant at night, but hear it throughout the day. It is absolutely unbearable tonight.

I've tried everything (shutting off electricity, water, gas) but it remains. I also hear it outside and cannot pinpoint where it is coming from. I'm not sure what to do. Any advice? I am getting about four hours of sleep per night and is affecting everything.

By anon332951 — On May 02, 2013

This is an update from Lulu, Sutton, Surrey, UK. I actually think this hum is being created by satellite towers and the broadband that is being rolled out across the country.

This sound cannot be recorded, so anyone attempting to record it will be recording other noises and not the actual hum.

The hum is an audible sound wave in the air and cannot, for some reason, be heard by everyone. There is a block of flats down the road from me that have a bunch of satellite towers on the roof. There are about 12 to 15 floors in this block of flats.

By anon331919 — On Apr 25, 2013

I live in Prague, in central Europe, and have been hearing the hum for four years. It has changed every aspect of my life, and it alters over time. The frequencies seem to accelerate. Now I can hear two distinct sounds: a very low drone and high-pitched buzzing.

For those who are new to this experience - it might save you time and energy - there is no point calling the local authorities or sanitary control people, questioning the state of your neighbours' fridges and/or moving elsewhere in your city. I moved four times within two years. During the sleepless nights I read about anything you can locate on the internet. A study by Dr. Deming, University of Oklahoma, hum sufferer himself, seems to rule out the HAARP as a possible cause. Who knows? Others believe the sound origin is in the interaction between the ionosphere (charged more than ever now by the incessant solar wind) and the power grids so cleverly spread by humans all over the world. There are theories about electromagnetic and/or gravitational influences from the inner and outer space ranging from:

1) The esoteric: along the lines of the Earth transitioning from 3D to 4D and the related kundalini rising theory;

2) Probably slightly insane (no offense meant to those who believe in them): approaching hitherto undiscovered planet/brown dwarf star, space aliens buzzing at us for reasons known to them alone;

3) Really interesting: involving cosmic forces. The magnetosphere distortions and magnetic poles reversal (could explain some of the recent animal deaths), Dr. Paul La Violette and his gravity waves emanating from the galactic core, Dr. Brent Miller explaining about the gravitational pull of the giant black hole inside the galaxy center, causing the whole mass of the planet to vibrate at a resonant frequency as we approach and pass through the invisible gravity field spreading like a curving long-playing record all the way from the core to us, which would also account for the incredible increase in earthquake frequency and intensity, not to mention volcanoes (see the Pacific Ring of fire). And there could be more to come if we realize that gravity and the time-space framework are intimately linked.

Anyway, whatever the cause and the effects you experience (I know first-hand how horrible the initial stage is with the splitting headaches, dizziness, nausea, body aching all over, complete lack of energy and depression), I found that when I concentrate on my spiritual life, meditate and pray as often as I can and try to be as kind and gentle as possible even in my mind and feelings, the sound stops hurting me. Hope everyone finds a way to cope with it.

By anon331184 — On Apr 21, 2013

I live in Sutton, Surrey, UK, which is the lower slopes of the north downs south London. I have been hearing the hum for two years now and I am a female so it is not just men who can hear it. It was driving me mad and I found having the TV on low and some music in another room on low helped.

My partner and other people I have spoken to in the flats were I live cannot hear it. It also changes to a throbbing noise, and I always know when it is about to arrive because it sounds like I am listing to my heart beat.

Also, it is not just night time when I hear it. I hear it from 10 a.m.; there is no specific time. I hear it every day. It is there all the time with breaks in between.

I believe in God so I draw my peace from this which is why I can now tolerate the hum. Love and peace to you all. --Lulu

I'm sending an email to the press/local authorities in my country. The Hum has devastated the quality of my life in Limerick city, Ireland and I now live in Tralee, Co. Kerry, Ireland where I can still hear it.

By anon323208 — On Mar 04, 2013

I live near Gate City, Virginia and have been hearing this hum for a year and a half now. It begins after midnight and continues until noon or so. If I wake up, I cannot go back to sleep for hearing it.

By anon322416 — On Feb 27, 2013

This is global, not local, so there is no point in searching for local causes. It occurs even where there are no cell towers.

This is HAARP. HAARP facilities are now located all over the world, not just Alaska. HAARP creates low Hz vibrations that deflect off the ionosphere into the earth from extremely powerful transmitters located hundreds, or even thousands, of miles away, like those cars with subwoofers times a million. They can also zap us with satellites.

It is being done purposely and we are the guinea pigs. Its purpose is to prevent the deep sleep cycles we need to repair our immune systems. Also to make us sick and dependent on Big Pharma, to make us think we're "crazy", to give us Alzheimer's so we can be controlled, and, most likely, to sterilize us. The ground shaking vibrations can easily create earthquakes.

The world is controlled by psychopathic eugenicists who want most of the human race dead. For proof, read the Georgia Guidestones.

This also explains the chemtrails polluting our air, earth, and water, GMOs harming our health and sterilizing us, and seed vaults in the Arctic to restore the natural world once we are gone.

HAARP vibrations cannot be stopped. The satellite zaps can be blocked by Faraday Cages or even aluminum to a lesser extent.

The satellites also explain why we are hearing strange sounds and sonic booms all over the world. They explain why we see "UFOs", spirals, and pyramid holograms, all viewable online. Look up Project Blue Beam. I hope I am wrong. If this disturbs you, please consider turning to God for comfort.

I hear the hum in Hollister, California sporadically and I thought I was losing my mind, but after seeing all these other posts, I am confident that what I am hearing is real. Thank you!

By anon320480 — On Feb 18, 2013

I’m from Albemarle County, Virginia, U.S. and Post no. 85 was my first post. I reported a few months of low, pulsating, rumbling that I could silence with hands over my ears or a couple of books. Tight-fitting earplugs almost eliminated the sound. They definitely did not amplify it. To me, this was a definitive sign of a simple exterior source, and my searching for the source and postulating on more complex causes has been at times assuring, but mostly distressing.

In early February, the sound stopped. I am sure that one factor in my aural “experience” was one or more external noise sources, but I am also sure that, like chronic pain, the experience created, with the full “cooperation” of my psyche, (and possibly concurrent infection,) intracranial changes, a syndrome with features similar to pulsatile tinnitus and Meniere’s disease.

My old mother, who lives in Sarasota, Florida, suffered with Meniere’s disease for 18 months. In between episodes of blinding dizziness and vomiting, she was without any symptoms, but even in this relatively “short” time, her bodily perceptions, her scope of preoccupations, attention span, judgment all began to fail, and most people saw her as a remarkably unfazed, even defiant, during that phase. The air of the Gulf Coast is often thick with industrial pollutants and biological toxins. Any location on Earth is subject to transient inhalable pollutants.

A dam project in Charlottesville concluded it’s “grout curtain” activity recently. There apparently were no other complainants. I live 13 miles away, and they maintain that it never ran outside regulated hours. If I were fabulously wealthy, I’d build underground homes and facilities. There have also been recent flight-path changes over central Virginia. During those months, I was absolutely certain of the start and stop times of the rumbling. Those times were really at odds with any plausible single source.

I have chronic, often very challenging, radiating and referred nerve pain through my buttocks, legs and genitals. Sacral and lumbar defects can produce local physiologic changes and are sensitive to systemic immune response. A day before any cold symptoms, I’m “told” of an oncoming viral challenge by my nerve pain. The anatomy of the sinuses and ears are very different from the lower spine, but local hypertension, atherosclerotic blood flow, inflammation, immune response, and an array of weird neurology participate everywhere in the body.

There were a few times when, upon getting very upset, I’d lie down and also hear the onset of the rumbling. Covering my ears did block the sound, but did it also coincide with a quick-acting bio-feedback? I’m sorry for not composing this better. I just felt like some of these items might help a few of us.

It’s not been three weeks for me without that grinding, rumbling threat, but it feels like six months ago.

An update, after reading through most of the posts. The nearby power station does make some of the low frequency noise that pulses sometimes right before midnight, but I also hear the hum that sounds like an idling motor when the power station noise is somewhat blocked in the summer by trees. So I have two noises to deal with. The power company doesn't have the manpower to come out and see if the station exceeds the allowable decibel level.

The nearest cell towers are on top of a 800 hill about two miles away.

Those interested in seeing if there's a connection with cell towers can check proximity with a cell tower map.

If your city is not listed, find a nearby city then use the map to scroll to smaller cities than those listed.

They recently published a study about marine animals that are affected and disturbed by sounds, often altering their migratory patterns. So why wouldn't certain frequencies have an impact on our brains, too?

By anon320406 — On Feb 17, 2013

I live in Kamo Whangarei, New Zealand and am sick to death of the hum. I have called the power board to come and fix their, wires which they agreed to do, and even went so far as to install a new transformer on our street as we all believed it was the overworked transformer. No such luck. "Wah wah wah wah wah wah wah," is what it sounds and feels like.

A telecom microwave tower was installed in our town last year and we think it is responsible. I am one of the unlucky ones who can hear it. I cut the tree down in the front of my house and am planning on planting heaps more to help filter out the noise.

The noise becomes audible about 1.30 am and just won't shut up. It keeps going until I have to get up 6.30 a.m., then it seems to disappear once I am up. I now notice that it goes 24/7 and I am grouchy and so are a lot of my neighbours. I don't like how it makes my teeth sensitive and I feel leached of minerals. I'm glad to see that I am not alone.

By anon319819 — On Feb 14, 2013

I've been hearing this *certainly* for a year now, very likely even longer. I live in London and a friend who lives two towns away could also hear it.

I find it becomes very prominent at night and its intensity reaches a level where my brain feels like it is being compressed and my ears begin to ache or feel like they're about to bleed.

The sound is a low, deep, intense resonating bass tone. It seems to increase then decrease in intensity (pulsing), and does so at regular intervals (it increases and decreases over about a four second period, then about one second of silence and it repeats.) I can hear it both inside and outside my house very intensely. And as someone else has said, it can be likened to bass from a subwoofer, however I have ruled out this is not the source.

Would really love a genuine explanation for this. It really seems quite eerie and hazardous to one's health, at least.

By anon319793 — On Feb 14, 2013

I live in Paola, KS. I started hearing a low frequency two-toned hum about six months ago. It would start around five in the morning and continue all day. Now it goes 24/7. I do not hear it in any quiet places besides my home and the community college I attended in town. My wife does not hear it at all. I have gone as far as shutting the power main on the outside of my home off, but I could still hear it. I am starting to believe that it is coming from the upgraded 4g cell towers going up around the area. Whatever is causing it, it is a horrible thing to deal with.

By anon319607 — On Feb 13, 2013

I hear a hum 24/7 that sounds like a low bass electrical hum. It stops for few seconds on and off. I first heard it around September or October 2012, and I now hear it every day, but at night it is more noticeable.

I live in Waterdown, Ontario, but I have also heard it in Oakville near Dorval while working in someone's house. I have also heard the exact hum in Chicago, Illinois, while visiting my daughter. I thought it was something nearby, but when I heard it in those other areas, then I was really surprised.

This led me to look it up, and I was surprised that there are others around the world who have heard it. I have no clue what is causing it, but I am curious, and sometimes it does get annoying. By the way, when I point it out to others, they hear it too, but it seems that some hear it more than others.

By anon319449 — On Feb 13, 2013

I live in Rockland County NY, and I hear the hum all the time. It's extremely frustrating. It's especially loud during the night. My husband never hears it, but my daughters do hear it when I point it out to them. I would love to find out the cause of this.

By anon319429 — On Feb 12, 2013

I am also in Charlottesville, but really in the county near the new shopping center. I also feel my entire house vibrating. It sounds like a large machine is drilling into the earth or through the earth. One night, my wife was outside and I was inside and we both witnessed an explosion that seemed to come from everywhere and nowhere. It shook everything in my house briefly.

I went outside to check on her and car alarms were going off and she felt a slight compression wave outside! I could never find a mention of this in any media outlet. It was around midnight last week and was huge! Anyway, I came inside after that and could hear that constant hum vibrating the crust.

By anon319338 — On Feb 12, 2013

Finally, a place where people have something in common; too bad it is the hum. I live in the country in Eastern Tennessee, USA. There is a constant hum here, and it's not only at night. Sometimes it gets so loud it almost sounds like a metallic heartbeat. Most of the time, it is a low rumble heard both inside and outside of our home. My husband cannot hear it, but he wears a hearing aide in one ear and in the other he is completely deaf. My 15-year-old daughter and I can hear it. I just found this out last night. I started to hear it getting louder, sounding like bass in a passing car. I asked my daughter if she heard it too and she said she hears it a lot and it truly creeps her out when she wakes up and hears it loud in the middle of the night. We used to live in Denver in the city and when we heard noises, we could usually explain them, but here in the country this is not possible.

Sometimes I am positive I can feel its vibration. It is kind of creepy. I called my father last night and asked him what he thought about it, since he and my daughter both confirmed hearing it. He told me he had heard it before and he heard it very loud when he and my mom and brother and I (when I was a middle grader), lived in Bozeman, Montana. That was in 1989. We have lived in a lot of different states in the USA including Alaska, and have heard it in only a few different states -- that is, my dad has. I have only heard it in Nebraska and here in Tennessee. Only here in Tennessee, it is very loud.

Yesterday about 10 a.m., during the day, I was in my home office as I am now. My husband was at work and my daughter at school. I heard a very loud mechanical heartbeat type sound – eerie! Even now as I type this, I hear a constant low rumble. I hear it in both ears, as do my father and daughter. It just surrounds you. Whether it is coming from underneath or up above, I can't tell.

If anyone on here lives close to East Tennessee, and is hearing this, please let me know. I hope one day the source will be found. Even though no one has been harmed over this, besides losing sleep, it frightens me.

By anon318113 — On Feb 05, 2013

To all fellow Hum suffers, if you are unfortunate enough to hear this obnoxious sound and feel its vibrations, please submit your location and take the World Hum survey (anonymously) online. There is a world map of the Hum being constantly updated and it seems it is growing pretty fast. Your information will be greatly appreciated, as there are still a few people who dedicate their free time to investigate and stop this maddening human error.

I personally believe that the Hum is being caused by the Smart Grid (dirty power etc.) and the BPL, with conjunction to the microwave towers, as someone else has already pointed in post 84. Victor Nixon (RIP) was the person who has exposed the Hum. But even if you are not convinced so, please submit your info and share your experiences through the two main Hum forums. The Hum/vibration must be properly investigated and all of your information will be very helpful!

Greetings from London, UK (a sufferer since March 2012)

I live in Boston Lincolnshire, and the so called hum is making my life a misery. My husband says he cannot hear it, but at night it wakes me, and the insidious constant whine makes sleep impossible.

I am 66 and I have always had tinnitus. It is a loud whistle that I am used to and accept, but this invasive droning noise cannot be ignored. It is worse when I lie down, it is everywhere in my house and earplugs do not help. The only way I can make it go away is to play music via headphones, but that in itself keeps me awake. I am tired all the time and bad tempered because of it. Can no one offer a solution?

By anon315627 — On Jan 24, 2013

I live by marine base camp lejeune in NC. The low frequency noise from the V-22 Osprey aircraft is killing me. I feel like I have the flu, my head pounds, I get diarrhea, chills and sweats and every muscle tenses. I write this now in tears. When they stop flying, it all goes away. I put my house up for sale but may kill myself before I can leave.

By anon315482 — On Jan 24, 2013

@anon285586: We also hear the exact same noise, East York area. Can't figure out if it's a nearby apartment building's heater sputtering to life - that would make us feel better if we just knew what it was. Any ideas? Any feedback from your local government representative?

By anon315191 — On Jan 22, 2013

@Adelbert: Based on the times, it could be underground tunneling, maybe for the construction of a secret facility. They're all over the place, and more being built as time goes on.

I lived in Taos (I now live near Richmond, VA) for five and half years, and I could never hear the Hum until the last summer I lived there. As it's often described, it sounds "like a diesel engine running far away, but not quite."

I was in some mountains south of Taos, in an odd place that had no insect or bird sounds - nothing except what sounded like a stream running by a bluff. Only there was no stream there! None.

I wonder if that place is connected somehow to the Hum; some there say it is.

By Caraboo — On Jan 20, 2013

@anon314602: Good to hear from you. I am not sure what day you posted, that the hum was rocking in the North Woods, but it seems like it was about a week ago that it was crazy here.

I went to stay a few days in the Black River Falls area, my friend and I were watching the news, (I hardly ever do) and on there they were saying that the windmills going up everywhere were making people sick, because of the sound that emitted from them. My friend looked at me, and I looked at my friend. They are putting some type of ordinance into effect as to how close these windmills can be to any residence.

I am not sure this is our hum, but we are not alone. We with our exceptional hearing capabilities. My friend thought maybe I was able to hear the earth's plates, or fault lines, moving, with the shifting that must be taking place as the ice melts and our environment changes. It sounded reasonable.

Watching Nova, as they explain, the poles are changing, etc. I do know it can wear on a person's health. It may not sound so crazy to some of you, that after long duration, it seems to feel as if my vital organs are swelling from the constant vibrations -- including my brain. I am not talking about a headache either, just a swollen feeling. One of my doctors actually asked me if I had ever heard of the brown note.

It's s Some kind of frequency created and used by the military to control gang wars. I researched it and it seems to warrant some consideration as to some explanation. Mostly we speculate. Still and all, it is nice to know we are not crazy and we are not alone.

By anon314633 — On Jan 19, 2013

I'm Tony in Plymouth, Devon, UK. I've heard that awful hum for a couple of years now. I live in southwest UK, and that’s where I hear it. However, recently I stayed in Liverpool which is in the northwest UK, and I could hear it there as well.

I'm only affected by this hum in my right ear, like one of the other posters here. I'm able to stop the noise by cupping the palm of my hand over my affected right ear. I'm also able to stop the hum by using dense wax ear plugs (the foam ones don’t stop it), but I tend not to use the wax plugs due to them making my ear pulse, (pulse as in I can hear my heart beat when wearing those wax ear plugs).

First, since I can hear the hum in Plymouth and Liverpool, whatever is causing it can’t be local. It has to be national in scope. (Plymouth to Liverpool is about 320 miles in distance).

Second, since I can stop/block the hum from bothering me by cupping the palm of my hand over it, then it has to be external, and it has to be real.

Third, since I only hear the hum in my right ear, I have to reason that, for whatever reason, my right ear has different dynamics than my left ear, that the physiology is somehow different in my right ear, and my right ear for reasons unknown to me is able to pick up lower frequencies then my left ear. For example, recently I was doing some data recovery for someone who had a dead laptop, I removed the hard drive from that laptop and connected it to a USB devise that powered that hard drive up externally. As soon as the hard drive motor reached maximum speed, I heard the usual low hum that these devices emit, and the next thing I knew I heard the hum. I stopped the hard drive and the hum went away. I powered it back up and the hum returned, and when I say hum, I'm talking about the same kind of hum that’s been affecting people worldwide, i.e., that extremely low frequency subtle droning noise that varies in frequency in the same way as a refrigeration compressor does. Again, when I cupped my hand over my right ear, this droning hum that the external hard drive was making sound stopped.

I know the navy uses ELF technology to communicate with submarines below water (ELF as in Extremely low frequency), so maybe it's this that people are hearing, and maybe not everyone hears the hum on account of the fact that maybe not everyone has some sort of issue with one or both of their ears. I'm sure of this, however: if it is an ear condition that’s causing people to hear this hum, then maybe that ear condition always did exist, and was waiting for just the right frequency to be invented, one like ELF, or something else in our fast developing technical age waiting to trigger our defective hearing system and in turn drive us insane. I'm guessing, of course.

By anon314602 — On Jan 18, 2013

@Caraboo: Yes, I also hear it in the North Woods of Wisconsin. The sound I hear is low, like a fog horn, but in much briefer intervals - pulsing is the word. Tonight it is really rocking! I hear it in the evening, and generally only in the winter. But if I open the door and listen, I do not hear it coming from outside. My husband cannot hear it.

By Adelbert — On Jan 12, 2013

I have heard a very low, penetrating, irregularly-pulsing sound since October. My family cannot hear it, thank god! I had never heard of any such phenomenon before going online, and as soon as I found that I wasn't alone, I stopped reading. I have a chronic painful condition and I have to stay put for a couple more years, otherwise I would move.

This sound, which I can hear readily throughout north-western Albemarle County, Va, once away from highway and train noise, often starts up at 0445 or around 0900. It often will cut out for an hour or so at midday. Sometimes it stops around 2100, other times running until after midnight. There is some variability, but seemingly industrial in its pattern. My very first thoughts were: boring, pumping, grinding, gravel-crushing, or a generator. After much driving around and asking, I have no idea where or what it is.

My house seems to change the sound, making it more penetrating. I can block it by lightly holding my palms over my ears, or holding two paperbacks against my ears.

I have only reported it to a couple news reporters and County officials here in Charlottesville, but I will report it to several more news groups.

You're welcome to contact me if you present verifiable name and address first. I don't want to talk to anyone who would ever read or post on a conspiracy or UFO site. This rumbling is driving me crazy without *that* too!

By anon313457 — On Jan 11, 2013

I began hearing the hum a year ago. It coincided with the implementation of the new smart grid infrastructure in our area which consists of Broadband over power line and thousands of microwave transmitters mounted on cell towers, light poles, power poles, smart meters, etc. It's a toxic sea of pulsed microwaves and dirty power. I believe it's intentionally being done to harm us. No one seems to care until they realize they realize that they're being affected by the stuff.

By anon311613 — On Jan 02, 2013

I've heard the hum for over seven years beginning at my cottage on the Severn River near Georgian Bay, Ontario, Canada. At first I though it really was diesel locomotives idling in the woods since there is a railway bridge and siding a few miles upstream from our old place. The sound is as commonly described, low frequency and shifting slightly in and out of phase as you would expect from a multi-unit lash up of locomotives. Non of my cottage neighbours admitted to hearing anything like that, and offered me another beer or two and a place to sit down in the shade. Then three years ago we purchased a different cottage much further downstream and the hum persists.

Now at my home northwest of Toronto, I have several new cell phone towers around me and the hum is constant day and night and louder, to the point of being very invasive. I used to enjoy listening to the stereo late at night with the volume turned way down, no longer a possibility as the hum drowns it out.

I deal with the noise by simply accepting that it exists and there's not a whole lot I can do about it, but during a recent trip to Vancouver my wife told me she was hearing the hum out there, as I was. So, I'm getting a little more concerned about this.

Personally, I will be using my cell phone with the speaker on and several inches away from my head after watching the excellent documentary 'Resonance - Beings of Frequency'. I remember a time when we had no cell phones and things managed to get done fairly effectively. Once my contract is up I don't plan to renew it. Call that voting with my feet.

I live in Eugene, OR and noticed the Hum after moving into a townhouse complex about 75 yards from a sub station. I didn't hear it in my first house here, up in the hills, under the cell phone tower. I couldn't ID the source of the deep motor-like sound that intensifies at night, pulsates then stops for a period, usually around 11:30. I assumed it was the power sub-station, and when I called to complain, they said we should expect sound from a sub-station.

There is no microwave tower or cooling station nearby, and no underground drilling. The power company is coming out to measure the noise output. There are limits to the decibels allowed and they will build sound barriers if the station exceeds the limit. But I wonder if it's really The Hum I'm hearing.

I plan to ask other townhouse owners if they hear it too so I can collect a body of "evidence." I will report on the outcome.

Reading this was like an affirmation. I hear the low hum at night too. It's so low it even hurts my ears.

I must point out that is it mechanical or electrical in form and not a natural phenomenon. This is because the tone changes and oscillates.

And it's not in my ear canal either, because it disappears when I wear headphones.

It sounds like it is underground, to be honest, and indicative of a distant, large mechanical device like a pump or factory.

I encourage sufferers to look at Google Maps, satellite views and examine larger industrial premises near to your location.

I think the key thing to point out is that much of the hum or vibration noise people experience is not their ow problem, but usually caused by rich, powerful people and organizations that don't think they have to respect the rights and property of others. They want the masses to be confused and not know where to fix the blame.

You are supposed to suffer silently and "wear earplugs" if you don't like it. Meanwhile, those causing the noise and vibration pollution live in secluded, noise-free, gated communities.

I live in Central Texas, in limestone hills. I have heard the hum for the last two months and it is constant all night long. Also, I can hear it during the day when there is no wind or traffic sound. It does sound like a woofer or AC hum but it varies slightly in pitch.

I live about one half mile from a cell tower and wonder if that can be causing the sound. I have used ear plugs and shooting muffs and that kills the audible. I also use a satellite radio at night to mask the sound, which is more irritating than the radio. I am losing sleep and my wife cannot hear the sound. I think it is below 60 Hz.

By anon307396 — On Dec 05, 2012

I live in Bristol, in the West of England and I record sound for a living. I first heard the Hum in 1996 in Shepton Mallet in Somerset, about 20 miles from here. In Bristol, the Hum is more prominent at night and in the winter. The hum is quickly dispersed by other sounds but comes back when there is nothing else to replace it. This makes me think it is inductive or harmonic resonance of other low frequency sounds in the ear canal and is mediated by the size and shape of the ear cavities. This might also explain why I only hear it in my right ear.

Whatever anyone may speculate, the source of the Hum is definitely artificial to my hearing. It is too constant and sharp-edged sounding to be a natural phenomenon.

By anon307379 — On Dec 04, 2012

Beginning six years ago, I heard the droning vibration at night, almost every night for about two years. It was like an idling diesel - very annoying and made sound sleep impossible. I contacted the city and as can be expected, they didn't have a clue. Finally, an article appeared in a local paper explaining how the railroad was using a "giant" diesel generator around the clock a few miles to the south in soil boring tests.

Railroads never care about people and when they finally stopped their "business", the hum stopped.

By anon307245 — On Dec 04, 2012

I live in northeast Ohio USA and I started hearing The Hum in mid-summer 2012. At first I thought it was possibly a nearby gas drilling rig or some sort of construction equipment but I could never find it. It was so loud one day I asked my wife if she heard it. When we walked around listening and she finally said "no," I realized it was an internal noise.

I almost always hear The Hum in my home. I have suffered with tinnitus for over 20 years.

By anon305808 — On Nov 27, 2012

I'm in Vancouver and have been hearing it since 2008, perhaps earlier. I had my smart meter installed in January 2012, but I don't think that's it. I felt a physical buzz this morning, a day before the apogee. I had full body kundalini running through me -- not a massive charge, but more like an ongoing fever buzz or shiver. I can feel "things" rattle around in my body especially in the throat and neck area. Seven hours later, I'm still charging.

However the time for me is about 4:30 a.m. Pacific Daylight Time, and 5:30 a.m. in the winter. I wake up automatically. We are picking this up from the earth, who i believe is in some sort of long wave communication with the pleroma. See the sophia mythos from the nag hammadi.

By anon304456 — On Nov 20, 2012

I live in Southern California and I am currently hearing this "humming" noise as I type this comment. It sounds like a low frequency type noise. It's really annoying when you tell someone and automatically they think you're crazy.

I can hear this sound much clearer at night. I have also had abnormal static electrical shock in my room. The static shock is also driving me nuts! Both sound and touch feel really intense to me.

I now ignore and avoid trying to hear this humming noise. It's there, but I say to myself I have other things to worry about. As much as I try to avoid hearing this humming sound, it sometimes overpowers what I'm thinking or trying to do.

By anon303753 — On Nov 16, 2012

I have heard the rumbling for months now, and also a high pitched tone. My husband is also able to hear it now.

By anon303061 — On Nov 13, 2012

I've heard it in the Cascade mountains, BC since January. Now it has become very strong. I am just wondering if any of you have SMART meters on your homes.

It seems to have started here after they installed the new meters on the homes in my neighborhood, although I doubt it because I can hear/feel it when I hike to the mountain tops.

But who knows? It is 2012. Maybe the earth is grumbling because she is tired of being abused. --peace from Canada

By Caraboo — On Nov 12, 2012

Has the hum been experienced by anyone in the North Woods of Wisconsin? I moved here from Tampa five years ago. The humming has plagued me for almost the entire time I have lived here.

Sometimes, it quiets in the summer months anywhere from two weeks to a couple months. It does stop occasionally in other months but not for long. It seems to begin during the night anywhere from like 11:30 p.m. to 2:30 a.m.

It is true it is more felt than heard, and earplugs do not relieve the stress of the sound.

I just found out (after all these years of inquiring of locals who do not claim to hear it) that real studies have been done on it, but there are no real claims as to what it is.

By anon302324 — On Nov 08, 2012

I live in Denver Colorado. I'm 27 years old and I hear this hum. I described it to my husband like a big truck idling or deep bass of a stereo off in the distance. He can't hear it. It is so annoying! Maybe we are just special because we can hear whatever it is.

By anon302101 — On Nov 07, 2012

I live in Fairfax, Virginia. I've been hearing the hum every night (and only at night) for about a week. If I thought I'd have to live with it for years, I don't believe I could stand it. I can't sleep without earplugs now.

My wife can't hear it, but it is sometimes enormously loud, even though it is very low frequency - something felt as much as heard.

By Pearlygirl — On Nov 05, 2012

I have been hearing this since earlier this year.

I, like all others who experience it, have wondered after the source of it. I do not hear it anywhere else but here where I reside.

My question is, do any of you experience any other attendant or possible attendant issues with this? Any other physical manifestations?

By anon300838 — On Nov 01, 2012

i am so glad to find this. I had no idea what to think. I am in Hawaii, and I feel it often and when I do, it keeps me awake at night. I almost feel like I am about to have motion sickness, and get headaches after a few days of noticing it.

I am noticing tonight there is a full moon. Maybe there is a correlation with that to when I feel and hear the hum. Mother earth takes care of herself.

By anon300666 — On Oct 31, 2012

I'm from southern Germany and am not hearing that subsonic hum (at least at this time), either in my house or at my workplace.

However I was perceiving it (or something on its spectrum) when I was at a smaller, local airport in our area last weekend. I was walking around in the arrival hall, frequently gazing at the landing runway and parking lots for airplanes when I felt a silent hum. I went on to different areas of the airport building, but could not localize the source of this hum (I had heard of it before on the internet); instead, I was looking out for better perspectives to make photos of a plane parking outside.

Bypassing some exclusion zone in this airport main hall (as I said it's rather small and closed on Sundays) I could walk through to the foyer and it was intense there. That foyer structure is a wing protruding off the mainbuilding to the airfield and its walls are soundproof, which might have amplified the hum sound. I asked one of my family members who was with me if he could hear it, and he acknowledged that he could also hear it.

When I was leaving the airport, I wondered if an aeration plant situated underground could be the cause.

Maybe this is rather unremarkable, but I thought I should post it.

By anon299515 — On Oct 25, 2012

I have heard the hum in several different countries over a period of several years. It is not the internal noise of the body, but there seems to be a frequency of the hum that connects to the body's natural hum and when the hum is loud, it wakes me from sleep and I have to put the radio on.

Sometimes when it is loud, it sounds similar to a struggling idling diesel engine, and another time it is a constant low hum, and at other times, but less frequently is a mechanical sound of metal grinding whirring and juddering and then it returns to the idling sound. The sound never really goes away; it just gets lower.

I am the only one amongst my siblings who is capable of hearing the hum. For years I kept the fact that I hear this sound to myself. It is a relief to know others are hearing it too. Let's hope we will all know whats causing the hum soon.

By anon297976 — On Oct 17, 2012

I happily left Cranberry Portage, MB in July, thinking I'd left the "hum" behind. I first experienced it there in the middle of the winter. It was like a low-volume, randomized vibration in the back of my neck. It was somewhere between a sound, and a physical feeling - really, really annoying. One day, I tracked a similar vibration to a nearby heavy equipment garage, where a CAT tractor was idling.

Now I live in Thunder Bay, and after a few quiet months, it's returned. I started to wonder if I was hearing my *own* circulation! How could the identical sound have followed me 3000 km? Perhaps using ear plugs actually filters the sound so it's clearer. I feel for all you insomniacs.

By anon296021 — On Oct 09, 2012

The Hum is totally causing me problems and I don't know what to do to fix it. My partner is sick of hearing me talk about it! I'm sick of sleep medications that just end up keeping me awake. If anyone has any distraction techniques I'd welcome them.

By anon295730 — On Oct 08, 2012

Red Deer, Alberta, Canada here. Started around 5 a.m. today. Earplugs didn't help. It woke me up from a sound sleep. In fact, with the earplugs, I can feel it better. It's the same amplitude and frequency inside the house, outside the house, upstairs, downstairs, in the basement, everywhere.

It's not anything in the house. I've turned off the power to try and isolate it, but nope. I went outside and it seems louder in the sky to the east. We had low fast clouds this morning, cool wind, about 5'C. I thought it was my noisy neighbor, but this isn't music or video games.

I would describe the sound as a distant air conditioner running, but not as constant. It's worse when I'm lying down in bed, but it's still there when I'm standing up, too. It has random peaks and valleys in the vibrations. It sounds like ~30hz, but I'll have to break out the microphone and see.

By jmaye1 — On Oct 05, 2012

Great to hear that others can sense this sound. I live on the Sunshine Coast in Australia and for me, this is a low tone that is felt more than heard and in the mornings when other sounds are so quiet.

I was quite sure that it was external because of its "digital" nature; it feels like a very low tone that rumbles for a few seconds, then seems to cut out abruptly (or possibly switches to a frequency that I can't hear)for a second or two before the cycle starts again.

I can listen for it anywhere (other suburbs, towns, etc) and, at that time of the morning, can always pick it up. (I mostly try not to listen for it, and like others, no one else I speak to can hear it!). I assumed it was the phone towers and, after reading these posts, think that the on-off cycle is the wave interference.

I'd be very keen to know if it can be heard where there is no phone signal! What about in a steel framed house?

By anon294598 — On Oct 02, 2012

I live in Dallas, Texas and just did a search on hearing a hum as I thought it might be a health concern. I've been hearing the hum, but it's stronger some days.

I've checked around my neighborhood and there are no trucks or lawn mowers or any heavy equipment that would explain the noise. I hear it constantly (at the same level), in different parts of the house and immediately outside.

By anon293684 — On Sep 27, 2012

I live in Waikanae, New Zealand and the hum is alive and well here. I agree and can relate to the descriptions and comments most of you have written about the sounds like a truck idling outside. It's a vibrational noise that's almost deafening, and I'm sick of asking people, "Can you hear that?" Some can and some can't. Obviously, some of us chosen few are more sensitive to the noise.

It is now a 24/7 hum noise and it goes day and night. I am lucky if I get a few hours sleep before it wakes me. A year ago, I could get a decent sleep, but now, forget it. It's hard to find a place where I can't hear it, but I have found a few spots.

I think it's also possible geostress too, and NZ, well we are smack dab on the ring of fire. Or I think it's electric smog in microwave rays from mobile and radio towers -- perhaps HARP. It's pervasive. I hear the noises inside the house and have walked outside the house and I can hear it.

All I know is it's getting worse and I have to move. Abandon ship! Shielding against 'it won't stop the noise, in my opinion.

I have an EMF Spy meter and whenever I hear the noise, I turn on the meter and the reading is through the roof! So it's a high frequency noise which makes me think it's mobile or radio wave related. Crazy stuff.

By anon293286 — On Sep 25, 2012

I live on the central coast in California, and the hum started about four years ago. I thought it was the neighbor's water heater at first, but then I noticed the sound outside! When I moved down the block I noticed the sound there, too. At first I thought it was a generator at a pot grow house next door, but the house got busted, and the sound persisted. It sounds like a diesel truck running and idling in the distance, coming in and out, but it is constant.

I recently spent the night in a town closer inland, Atascadero, and I noticed the hum strongly there, too. I asked my hosts about it and they said a neighbor lady had complained about it years ago. I see the poster above me started noticing this four years ago, too. I was recently very surprised when a local friend of mine said, “Hey. I've got proof of the 'hum'.” I had never discussed it with him. He took a high-gain digital audio recorder and we walked to where it was dead quiet, except for the hum, which we could see pulsing on the VU meter of his recorder, which has very sensitive condenser mics and high gain preamp. The sound is unpleasant, and is conducive to anxiety, so I sleep with a brown noise generator and a fan to block it out. I have had tinnitus across the various spectra of hearing, and this sound is definitely outside my head.

By anon293061 — On Sep 24, 2012

I live on Camano Island, WA, and have been hearing the hum (sometimes louder, sometimes softer, but always constant) for several months now. Sometimes there is also a deep, low, intermittent rumbling sound that is neither aircraft nor thunder.

I first really noticed the hum in the spring of 2012, but it had been there for a few years; it's just gotten louder. The rumbling started around June of 2012. It vibrates the whole house. If we set a glass of water on the table and watch it, we can see the vibration ripples and they never settle down. They are constant and the water never gets still.

I cannot sleep for this, and would love to know what it is because it's driving me crazy!

We are in the South-East England region. We've lived in the same house for over 10 years and never heard anything like it. Last night about 9:30 p.m., the children came down from their rooms complaining about a 'humming noise.' I couldn't hear it downstairs and said perhaps it was something next door.

In the morning about 7 a.m., I got up and could hear a pulsating rhythmic humming which seemed to center in my living room. It then got louder and louder and seemed to fill the whole house. It stopped about 9:30 a.m. I even asked a friend to listen (and he couldn't hear anything!) It went on for 12 straight hours. I found it odd the noise went from 9:30 p.m.-9:30 a.m. almost to the dot.

I checked all the electrical equipment and turned off stuff and couldn't find anything emitting the sound. What I find strange is that I and the children could hear it, but the friend could not. We live near to a television transmitter but on checking on a monitoring site, found no work was being carried out, etc.

I rang Environmental Health and reported it, I think in the vain hope someone else may have heard this weird noise locally too! I did say to the officer, you might think I'm completely nuts, but... He said he hadn't heard of any such noise complaint before. I found this site upon writing in the search engine 'weird humming pulsating noise in house.' I feel a little less like I am going a bit nuts now!

By anon291679 — On Sep 15, 2012

I would suggest that we start looking at underground activity such as large face directional boring. A lot of it's kept secret but a lot is just plain old civil works for new sewer and water mains. The boring process usually creates a harmonic hum of between 6 - 40 hertz depending upon the diameter, rock and soil types encountered. When they were building the so called secret bunker at Bungendore the hum could be heard for almost two and a half years.

By anon291561 — On Sep 15, 2012

I've heard similar sounds in Belarus. The territory of Belarus is entirely located in the western part of the old East-European platform. These sounds are strange for me. I think an electromagnetic processes in the ionosphere or a natural geological phenomenon are able to create these sounds.

By syvreta — On Sep 11, 2012

I live in Tuncurry, Australia and have just moved home and this hum started about two weeks after I moved in and it has been most noticeable at night. My life is fairly normal really, as a retiree who is not one for being over excitable about anything. Anyway it is 3 a.m. and I still cannot get to sleep with this incessant hum. I tried walking outside to locate the source and then got out my laptop to investigate since I cannot sleep.

It seems that only about 10 percent of the population can hear it! I guess it must be some sort of energy thing to do with the sun and magnetism of the planet. As you can tell, I am not a very technical person.

I live in Menlo, Washington and I have been hearing the hum for going on four months now. The sound never stops. I have investigated my home for the origin of the sound, and it is not coming from my house.

I live on eight acres of farmland, the closest bigger city is 30 miles away, there are no power lines anywhere near me, and no factories. Let me just tell you what is here as that will be quicker.

My town has one 120-year-old store, a very small high school and a very small fairground. There are no traffic lights or stop signs. There is one road, SR-6, that runs through my town so there isn't anything the hum could be coming from that's man made.

I would describe trying to track down this hum as trying to find the end of the rainbow; the closer you get the farther it moves, and you cannot pin it down!

I cannot record it. It's sound is constant, although one time it stopped for an hour. My husband heard it once when he really tried but hasn't been able to hear it again. No one else hears it but it is as plain as day to me. I have to turn on a fan at night so I can sleep. My horses and pets don't seem to care about it. Very strange!

By anon289199 — On Sep 03, 2012

I heard this hum last night. I live in Doncaster, England, and it started about 2:30 a.m. and lasted at least 30 minutes. At times the pattern was consistent and then every now and again it was as if a matching hum started and lost pitch with the other creating almost an out of pitch harmony.

I managed to record the sound faintly on my iphone and it really is a strange sound.

By anon288718 — On Aug 31, 2012

I live in he Tampa Bay area of Florida. A group of us -- about 10 or more plus my neighbors -- have been hearing this so called Hum coming from the east and possibly the sky. It always happens between midnight and 3 a.m. and lasts for about 30 minutes or so.

I called the US Coast Guard like a nutcase would do, just to figure out if it was anything they were doing at the closest airports like engine testing or whatnot. They were not at all and told me I shouldn't be able to hear engine testing from how far away I am, anyway.

My girlfriend and I also got in my car and drove around for about 15 minutes on one of the noise nights trying to locate it as well. No luck. It's been going on since July and a few friends and I plan on doing some driving around and real investigating every other night to try and debunk this whole thing.

We live in east-end Toronto, and since we returned from vacation last week, both my wife and I have noticed a low rumbling noise. I know this is vague, but it's either coming from somewhere in our building (and I will direct inquiries to the building superintendent to figure that out) or from some nearby industrial project.

It certainly doesn't sound like an air conditioner, but rather like industrial equipment large enough to make the "persistent, invasive low-frequency sound" mentioned above. It rumbles to life for a couple of minutes, then sputters quiet. It occurs around the clock and seems most audible at night.

Obviously, we're grasping to fill in the blanks, but this noise really gets into your head. It's even awakened me from sleep.

I'd appreciate any east-end (North York) Toronto perspectives. I've also made inquiries of our city councillor.

Thank God I found this forum! I kept thinking it was some shift worker with their music going all night. I live in the country in the Barossa Valley, South Australia. It sounds just like that or a car idling outside. It's been going on for about a year. I sometimes look outside the front door thinking it must be a car. Like others have said it's worse in one room and doesn't seem as bad outside. I have tried earplugs as well but they make it worse.

I was thinking of moving, but by the sounds of it I might move and it could be just as bad if not worse. Does this mean we all have to live with this for the rest of our lives?

I've heard the engine idling/popping low frequency hum in the Vancouver/Langley area of British Columbia, Canada 24 hours a day for six months now. I drove six square miles in my truck one night and heard it all over.

A researcher, Dr. Chris Barnes from Bangor UK, has compiled interesting information about the Hum. I recommend looking him up. One of his theories is that our exposure to microwave radiation from wireless technology increases our sensitivity to low frequencies.

Professor David Deming (Oklahoma University, USA) provided an excellent research paper called "The Hum - An Anomalous Sound Heard Around the World."

About 5 percent of people around the world are disturbed by the Hum. There must be a reason why it occurs in developed/industrialized countries.

Hello from Northwest Canada. I was badly affected by the Hum (rumbling sound or vibration like an idling truck) for the first half of 2011, which caused insomnia, headaches, etc.

In my case, I don't know why it mostly stopped after July 2011 (a year ago), as I didn't change anything in my lifestyle. I'm guessing that it is caused by new wireless technology, whose impact we don't fully understand yet, and which could be interacting with natural variables such as the geomagnetic field, which could explain the variations.

There's a new documentary that will soon be out, “Resonance - Beings of Frequency,” by James Russell, regarding the potential impact of radiation from wireless technology.

More information is available in the documentary's trailer, found online.

I've lived in Florida for almost 30 years, and now I'm hearing this freaking hum in my home. It started when the meters where changed to smart meters. Maybe I'm wrong, but my research led me to believe this is a microwave auditory effect from microwave emitters generated from electrical towers the electric company installed. These microwave pulses somehow emit a frequency beyond our hearing,

but that affect the brain.

This is a form of mind control against society and the electric/phone companies are all involved. They are controlling the way we think and behave. It is world wide because the elite are afraid of us! Solution: Shield your home as best you can and always think happy thoughts and stay healthy. Good luck.

I hear a ringing. I believe it to be tinnitus, however, sometimes the pitch changes drastically. It sounds like a large piece of electrical equipment is being turned on or off. It's been going on for years.

Tonight I awoke and it was and still is louder than usual, and I noticed the colors one sees behind closed eyes were extremely vivid, but after a minute were blacked out. I am beginning to think the sound and the colors are linked. --Minnesota.

I live in Boulder WA. I'm not mental, but I experience the same problems everyone else on this blog is talking about. I hear this hum but only during the winter months. As soon as it gets warm, it disappears. I can even hear it in the car and on very cold days outside.

For days, I've walked the streets in the early hours trying to locate this hum. The other day, there was nothing. I was so quiet I had trouble sleeping, and then I saw that KCGM-super pit did a noise survey and the noises were within acceptable parameters. The following day the hum magically reappeared.

I live in Antofagasta, north Chile, in the Atacama Desert. I started hearing the "hum" at the end of 2011. At first I thought it could be the traffic noise front my flat, but I realized that it sounded from far the avenue. So, I thought it could be some engine or even the waves (I live near the sea). My husband and son didn't hear a thing. Finally, I was led to admit that the sound was in my head.

I suffer from tinnitus and I know the ringing sound is inside my ears but I heard the hum outside of them. So, it is not in my head. I didn't go to a doctor because I realized that he would say that it is tinnitus - the same experience some had in this blog, so why spend my money on a worthless visit?

I noticed the sound more in one part of my house than in others, and it is louder on some days or at hours than on others.

What I do in order to not become crazy is the same I do with tinnitus: I think about it as something that has no cure, so I try not to worry about it. But some days (like today) it is so loud that it is impossible to ignore. That's why I looked for information and found this place. At least, I'm happy I'm not nuts and I'm not alone in this.

Last month I heard the hum in Brighton, Melbourne for five nights and could not sleep at all. It vibrated right through my body and was very disturbing. It was way louder at night and in my bedroom near the eastern window than the other side of the house.

Sometimes during the day I could not hear it at all, maybe due to background noises like traffic. When my head cold and sinus cleared after a course of antibiotics, it went. I figured it must have been audible when I had this sinus and head/ear cold. I truly hope all of you get rid of it. Don't give up.

It's quite blatantly HAARP. Do the research and wake up to what it is doing to us! The voices are transmitted, and the booms, humming, strange clouds, etc., can all be expected from this 1gw laser.

My wife and I have been suffering a low frequency noise since early January 2012. We've lived at our property in peace for 19 years and seven months. Then came the low frequency noise mainly in the early hours of the morning causing sleep deprivation – big time! We went out in our car, searching for the cause and to find a source. A few weeks later we did: cooling towers at a factory on an industrial site about a quarter of a mile away. We then found out that a cooling tower had malfunctioned during the Christmas holiday period. They (the company) were in a state of denial about it and were not helpful at all.

We then called in the Council's environmental officer who could not hear the low frequency noise and dismissed it totally. We went to a higher level at the authority to seek a second opinion. This was a little more positive and felt (at last) as if we were being taken a little more seriously. Sound meters (museum pieces) were left at our home, however they could not pick up the low frequency noise. Annoying? Yes! They did continue their research and at last agreed with us that the horrendous 'hum' was indeed emanating from the cooling towers.

Now, five months and 24 days after of this horrendous torture, the factory is hoping to repair/replace the faulty cooling tower system(s). Watch this space. I have been diagnosed with multiple sclerosis for 24 years and all of this has had a totally negative impact on the condition. My wife (also my caregiver) has suffered greatly too - an understatement! Devon, UK

We have been suffering the hum for five or six years, mostly at night.

Since November 2011 the level has gotten louder as more and more Tetra masts are put up ready for the Olympic sailing in Weymouth.

Has anyone tried one of those RF screening tents that they sell to sleep under?

Greetings from Northwest Canada.

I know what it's like to hear voices. I thought that was normal, until I was told that, no, most folks don't hear voices. The thing is, why should that be considered a problem? I heard what was said, some of it relevant or not, some of it my own projections or world view, sometimes intuition coming up to the surface, etc. Putting it in context was helpful, even useful!

As for the hum, that happened to me for about a year in 2011. Not so much anymore. It was really bad in March and April 2011, with vibration feelings or tingling, insomnia, pain in the chest, headaches and that nasty motor like noise, which was worse at night too.

Through research on the internet and my own observations, I've come to the conclusion that it's caused by a combination of factors: natural geomagnetic shifts in resonance with human made electromagnetism. Our dwellings are surrounded by wireless internet, cordless phones, microwave towers. In my case, I don't know why it stopped because nothing else changed in my life. I'm guessing something geological shifted.

Check the internet, especially the "Hum Forum". Someone there has discovered a tone generator frequency cancels out the Hum. Blessings to all.

I don’t mean to scare anyone I’m just try to find an answer to a problem I have had for the last eight years. I had started hearing voices which I was certain someone was doing to me but listened to what all my friends told me and went and got help.

I was put on various, different medications but none were helping. It is and was like someone is actually talking to me. I know exactly how this sounds, but when you try everything but still know in your own mind that which is true, I can’t lie to myself for everyone else anymore and have been looking for a way of explaining how this could be done.

All the symptoms you have all explained apply to me. I hear what no one else can, and the more I explain it, the crazier I seem, so for the sake of my family and friends I have hide this from them and pretend to be O.K.

I have held down a job working seven days a week for almost four years, as this was the only way I could cope until the strain got to me. As luck would have it, I only work a four-day week which gives me time to hide from everybody.

I can feel this in my bones and when I ignore what I’m told and ignore it, it feels like the amp is turned up. I feel sick. I tingle. I can’t eat. Please help me.

If anyone has done research into low level noises, please look into how to create a low level noise which is directional but instead of a hum you can talk through a microphone and be heard. This is not a game, I need help. I need you to prove that I’m wrong and this can’t be done, as I am not willing to just accept what I know to be false. Prove to me I’m wrong and that another human being can’t do this to me. Only then will I truly accept what the doctors had said to me, which was why would anyone do this to another person? The more I argued, the more mental I seemed until I just agreed, why would you do this to someone. My argument is why would you not if you could always get away with it.

I've recently move to a remote property in Australia and initially thought it was a mining operation, bore or similar. I mentioned it to three other people who live here, but to my frustration, they can hear nothing.

Recently, another friend arrived and confirmed it for me (thank Christ). But there is nothing around here for miles! I've even flown a radial search and hiked extensively over the last six months, and there is nothing I can find that emits this low hum. It can be ignored if I tell myself to let the sound flow through me, but if I stop and listen, it's there. It's a low frequency hum that changes pitch, like a slight miss.

By anon268294 — On May 13, 2012

I've been hearing this noise since February. For several days, it was only from 2:30 a.m. to 7 a.m. and would stop like it was turned off until the next morning at the same time. So I thought maybe my neighbors below me had a guitar amp or a surround sound stereo on base, but this hum also vibrates and I hear it even out at my parents' house in the county.

Then I started hearing it all day and night, only being turned off for maybe three or four minutes at a time but in mid to late April, it started changing kind of fluctuating in frequency and tone but still never stopping completely and I sleep with ear plugs. Those only muffle the sound, but I can still hear and feel it day or night really intense. Also sometimes there is a tiny "shock" feeling with it. When it's really high it's not only deafening, but my arthritis and fibromyalgia start acting up. It disrupts all my electronics, including my internet.

I just want to yell at someone to turn that stupid thing off already and let me sleep. And I hate that smell that comes with it, but like in the previous post, at least now I know I am not crazy, and definitely not alone. But why only select people? Why is this such a global thing with such limited research yet such an obviously extended history? Are we that juvenile in our own science and technology?

By anon267667 — On May 10, 2012

I just heard it tonight for the first time! I was outside, everything was quiet and all of a sudden there was that maddening noise and it won't go away. Glad to know I'm not crazy.

By anon267051 — On May 08, 2012

I heard it just a couple of days ago, Monday morning, 1:30-5:30 a.m. for the first time. I did all the usual things: check the house, go outside, tried earplugs, shut doors, slept in a different bedroom, etc. Nothing worked. It actually seemed to be louder in bed then outside. It sounded to me like a distant diesel motor that whines up and down, but goes on for hours.

It was definitely an external noise, not internal. I believe I have heard it before, but thought it engines. Very annoying sound and I lost a lot of sleep. It was even a little scary until I found all this information. Really nice to know I am not alone and I haven't imagined the whole thing. So, thanks for posting everyone.

I've heard it twice in the last month in the east part of my house in Cork, Ireland. Fortunately one of my housemates also heard or felt it. Both times in different places in the kitchen, a sound and vibration like a bass speaker being turned on really loud for about a second. I also have a high pitched ringing every so often.

By anon261188 — On Apr 14, 2012

I've heard the hum since March 2012. It sounds like a bass from a subwoofer when it gets the worst at night, but usually it sounds like a wind blowing in a huge metal pipe or car idling outside the house. It also has a second tone, higher pitched, like a beating or clapping sound. It can be heard better on the top floors than on the ground. It feels more like pressure in the ears. In fact it is such a low frequency that it is felt more like vibration than a sound (although in physics sound = vibration).

Earplugs -- even the wax ones -- cannot block it as the low frequency noise enters the body through the bones, thus entering the skull directly into the inner ear, and also causing nausea (because the vestibular system is part of the inner ear).

It keeps me awake at night and I rarely have a sleep for more than four hours. I am exhausted, and have a little one to take care of.

I have measured it at 31Hz peak, which, strangely enough, corresponds to the B (Si) of a 5-string bass guitar.

I have located it as coming from the back of the kitchen of a nearby newly opened restaurant. It seems that it comes from their condenser and refrigerator unit, combined with the vent. It never stops and also these appliances are never switched off, either. But the strangest thing is that I could hear exactly the same hum at my friend's house, who lives three miles away from my flat and there are no restaurants in the vicinity.

I have seen an ear specialist and they ruled out tinnitus. This hum is real and I feel sympathy for all those of you who can hear it and feel its powerful vibrations.

It ruined my Easter and I had no desire and power to celebrate it.

I'm so happy I'm not the only one going absolutely crazy with this. My husband can't hear it, but it keeps me up at night when it happens, as I not only hear the hum, but also *feel* it like a tremor. It's been hard for me to imagine that he can't sense it, since it feels to me like the whole house is vibrating.

At first, I thought it was 24-hour construction happening down the street, or trucks idling a block or so over, but no. Nothing like that at all.

We're in Toronto, and I've noticed that the hum is stronger around the full moon. It comes in rumbling waves, lasting about 10 seconds, and then there's a pause of about 5-10 seconds before it starts up again. Has anyone else noticed this?

By anon256528 — On Mar 22, 2012

I hear like a subwoofer noise at night. It was more audible on north end of my house. I could not hear it outside the house, but could hear it in another building on my property. No one else in my family could hear it. I do have sensitive hearing and can hear higher frequencies than others despite my tinnitus.

I consulted my doctor, and he believed me. My wife mentioned it to an ear specialist and he thought it was low frequency drone (similar to tinnitus) due to hearing loss. I cannot sleep without earplugs, and when I travel I do not hear it. I moved to a town several miles away, and I hear it even more. I was convinced some factory or nightclub in the area must be producing subsonic frequencies, but perhaps it is "The Hum."

By anon246842 — On Feb 11, 2012

To follow up on post no. 23, I believe they broke something. In the ground I heard a sudden bang! Perhaps it was in the aquifer because in North Florida it's extremely shallow and in the peninsula of Florida, often 10 - 30 feet below. A lot of strange sky sounds are heard from that southern Florida region, as well.. Coincidence?

Since then, these sound vibrations are at a muted level I can live with. I guess it was underground. Can't say much beyond that for sure. I'm glad I don't have think to move now, anyway.

By anon246417 — On Feb 09, 2012

It began about a week ago and before that, I held no interest whatsoever. I've pinpointed the local source to be about 3 km from where I reside under the city's regional airport, which happens to be on a bay. Living in a trailer in NW Florida, the invasion is most of the time. After two hours, the shock waves vibrating me have surrounded my whole living existence. If it stops, then I usually use that time to decompress. My short-term memory becomes diluted and practically dysfunctional. The pressure concentrates on my brain's frontal areas and intestinal tract, even causing me to skip meals. My mother's house is next door to me and I feel it on the heart more. It seems that concrete floors baffle sound a little bit to shift more pressures toward the nervous system than the stomach.

In any event, I've pretty well concluded that this is from some types of *generators* they are using like what's available to road construction crews sometimes, but to build 'end of days' subterranean fallout shelters. I suspect that it has something to do with the shriek noises also that other people of other ares are hearing that prevail above ground, as well.

It's the kind of a tingling you feel after just having an orgasm. Unfortunately, real orgasms won't be likely unless I decide to move. The longest run of this knocking-ebb sound has been 43 hours. It's more of a 'hum noise' above grounds, although only once you get near the proximity of the source.

Hope this helps isolate things and sorry for such a long read. Oh yeah, the generators might be using acetylene fuel that's highly combustible. My analysis is that some people and most all animals have this magnetite in their brains -- like an early earthquake warning detection. I apparently 'do' have some of that mineral occurring naturally.

By anon246109 — On Feb 08, 2012

I've been hearing a rumbling in Melbourne, Australia since I was a kid, decades ago, and still do. It's always late at night/early morning and mostly in summer. Seems to mostly be coming from the west. Needless to say, this predates any age related hearing effects, and certainly predates mobile phone towers and I'm about as far away from Alaska as you can get, even if there was such a thing as HAARP in 1975. Does the earth rotate on a bearing and does it need lubrication?

By anon229792 — On Nov 15, 2011

I have been hearing this in Kingwood Township, NJ ever since I moved here 30 years ago. It's the classic "diesel engine" sound as if one were idling in the distance. It is worse at night in general and at some times of the year more intense than at others. The best explanation I have ever heard is that the source is a gas pipeline located about a half mile from my house.

By Yukoner — On Nov 06, 2011

From Whitehorse, Yukon, Canada: I’ve experienced the same rumbling noise since the end of December 2010. It sounds like an idling truck, very low frequency, kind of pulsing. It is most intense between 2 and 5 a.m., or when I am lying down. It can go on during most of the day, usually with a lull in the afternoon and early evening. It has sometimes stopped for a week or so at a time. It has kept me awake at night, with a racing, irregular heart beat, headaches, feelings of vibrations, etc.

I searched for and eliminated all possibilities of mechanical sources. Traffic dies down completely here at night. There are no trains, no pipelines, no big industries in Whitehorse. We’re surrounded by hundreds of kilometers of wilderness. The closest active mine is about 200 km away.

This process of elimination took me towards microwave radiation as the most probable cause, probably in resonance with other electromagnetic phenomena such as the geomagnetic field, etc. which would explain the variations.

The one thing that Whitehorse has in common with locations of other reports of this rumbling noise or Hum, is the ever increasing number of cell phone and wireless systems, and my home is surrounded by that. We need serious investigation of this phenomenon because people are suffering.

Question: the worst rumbling episodes for me seem to coincide with earthquakes around the “Ring of Fire” and in North America. Anyone else who noticed that?

By anon224641 — On Oct 24, 2011

I first heard the Hum in Point Roberts WA this past July 2011. I thought it was a generator or some other mechanical device. However I now live in Surrey NC and hear it all over the lower mainland area, even in Sqaumish. After reading various articles on the phenomenon I am convinced it is not sound but some low frequency vibration. The best article I've read is one by David Deming of University of Oklahoma. He really went deep with his research, but of course this isn't going to fix the problem. Still, it's good to know that there are people taking it seriously.

I spend some time each night listening to Delta wave music, helping me sleep. The Hum seems to bother me less after that. Another remedy is to have a fan on or other "white noise" in the background.

By anon211499 — On Sep 03, 2011

I think it is the microwave auditory effect.

I've been hearing it for about six or seven years, mostly non-stop, inside and out in the yard or woods.

It started when the new generation of telecommunication towers were installed.

By anon198547 — On Jul 20, 2011

I would be concerned, hearing the Hum in Oregon (or anywhere along US/Can. coast), as one possibility (as is conjectured in Hawaii) is geologic/tectonic activity. Has anyone investigated Hum along the Ring of Fire, maybe a correlation?

By anon183823 — On Jun 06, 2011

I have been hearing 'the hum' for about a year now. I first began hearing it occasionally when I lived in Toronto, but at the time attributed the sound to trucks idling in the neighbourhood. I moved to Windsor three months ago and began to hear the same sound again, usually late at night. This didn't make sense though, as there are no large trucks anywhere in sight. It is a very quiet neighbourhood, so it is quite noticeable when it happens. It has awakened me at times.

A few evenings ago I stepped out on to the front porch of my house, having my coffee, and 'the hum' was quite intense. It would sound for a minute or so and then it would stop for a little while. then it would start back up again. When I went back into the house I could not hear it as well which makes me think that it is more 'in the air' than in the ground.

My husband, sister, and mother have heard 'the hum' recently as well. I know that I am not losing my mind (but I hope that the hum does not cause mental disturbances in the long-run).

By anon169767 — On Apr 22, 2011

I have had a high pitch tinnitus sound for a while now but i do frequently hear a low humming sound. Used to think it was a lorry refrigeration unit but ain't no lorry near by, wife never hears it. from dublin, ireland

By yorkshirelad — On Mar 11, 2011

It is definitely acoustic. I have found a type of earplug that can attenuate it, though they do not block it completely. (E-A-R Classic) Low frequencies are 'felt' as much as they are heard. Sometimes I hear it switch on, it is often loudest on a Sunday and during the night, it is obviously external. I have lost my job because of it and it is the noise that stops me sleeping not worrying about it.

By anon143375 — On Jan 15, 2011

The hum is real but I don't think it is an acoustical sound. Earplugs do not stop it.

I used to hear it in rural Clermont, Florida five years ago. Recently I have become aware of it in rural Citrus County. I would not worry about it and lose sleep. Its cause will likely become known.

By anon140900 — On Jan 09, 2011

I was wondering about the post by the farmers 23 miles south of Eugene. We also live in this area and my husband can hear it and I can not. It started for him with the last six or seven weeks. He does have tinnitus, but he says this tone changes pitch? One tone with another over it at times?

I started looking into this today when he came home from an outing outdoors in a remote location and could hear it there. It seems to affect him most at night.

By alaskagirl9 — On Jan 06, 2011

I live in Alaska and have for 15 years I'm about 200 miles from HAARP and have heard the hum nearly every night. Thing is I also heard it back home in Montana and several years before that back east in Ohio.

I feel all alone not having anyone to talk to about it. It's not an ear problem because that checkup came out great, so what do I hear? I'm going nuts.

I did notice one thing: whenever HAARP is on I get headaches really bad and feel dizzy and very tired. As soon as it's off I'm back to normal again. Explain that one? Anyone else in Alaska contact me. Going to take a sleeping pill and get some sleep. It's the only way.

By daisygeorgey — On Dec 26, 2010

happy xmas. Not. The hum has just ruined my xmas! I couldn't sleep xmas eve and xmas night was hell to bear. It was just like a row of cars was parked down the road with all engines going ready to take off! I had to get up and go online for respite.

i am so tired but bed is a suffer zone as it is heard loudest there, at all times of day.

My partner reckons it's low pressure but i don't know. Does anybody have a solution to this? I fear i will lose my job due to lack of sleep. i am so irritable it is making me unwell. From galway, ireland (incidentally we had a earth rumble in this area about eight months ago -- about 5 on the richter scale).

By anon117442 — On Oct 10, 2010

I heard the Hum last night last night with my husband, at our ranch 23 miles southwest of Eugene, Oregon, when we arrived home that evening. t had low vibrations and tone. All the insects and frogs were silent.

We checked all around the house to make sure there wasn't something wrong. We couldn't find anything. It is the first time since living here for 20-plus years, that we have ever heard anything like it. It was not there when we woke up this morning. I hope someone can comment on what this deep noise is.

By anon80903 — On Apr 29, 2010

I hear a noise that sounds like a car idling.

It sounds best at night but sometimes outdoors and then the sound is louder.

I've have heard for about three years' time. my 22 year old son hears it too.

About two years ago I had coffee with the neighbor in the kitchen, when I heard a long, low distant rumble, but my neighbor heard nothing.

I have heard the rumbling two times

kicki, sweden

By anon59975 — On Jan 11, 2010

i have heard this hum for about four years.

i have tinnitus, high pitched in one ear, but

this is different.

i have heard it in various locations. i asked my partner if he could hear it in manchester and he couldn't. neither could he hear it when he was in my home in newcastle.

i notice it more at night, probably because it's quiet. it occurs at different times of the day, though.

i don't think its a UFO. In fact i don't have any theories, but it is coming from outside my head.

i used to think it was in the flat above, a generator or something.
