02/12/2012 00:33:39At nightA low level but persistent hum at around 37 Hz [from memory of tests].
Sometimes it has a beat to it of about 1 sec, much like a diesel engine in the distance.
This is classic hum to hum to me.
I do get tinnitus, but this is completely different and preceded the hum as factor in my hearing..
Occasionally, sometimes for a few days or when changing location but ti always comes back.
Weather fronts can also alter the pattern somewhat so an atmospheric component is suspected.

I think there are many types of hum- some incidental, and some intentional, and not meant to be detected.
Sensitive hearers are put down by authorities too readily. Why?

Unable to record it using laptop, WM-61 mic (no preamp), Spectrum Analyzer software.Very seldom at home, but sometimes for a few days after a long trip (airplane or car).

02/12/2012 12:40:50At nightThe "droning engine" descriptions fits it pretty well. It sounds like a very distant idling vehicle, but there is also a vibratory aspect to it....akin to hearing the bass from loud music that's been muffled by distance and walls. Also like when you can hear/feel the bass from stereo systems in other people's cars.Yes, I don't always hear it.

02/12/2012 13:46:25Same day and nightI have heard this sound for almost three days. At first I thought it was a car or home stereo with a lot of bass power but, it has persisted for about 60 hours now. I live in a rural area without many close residences so, I took a couple of walks in an attempt to locate the source of the sound. No matter what direction I go or how far, the noise does not change. The sound is not a smooth or constant sound.

02/12/2012 20:06:51At nightVery low frequency Diesel engine like throbbing sound. Sometimes it drones on for long stretches before it has a short pause / throb, then picks up again, repeating the rhythm. Sometimes the droning / throb rhythm speeds up slightly and other times it has irregular quick throbs, similar to irregular heart beats.
Can't block it out even when plugging ears; therefore it appears to be sensed by the body, which interprets it as sound. Only hear it / sense it inside enclosures; in house, parked car in driveway and partially outdoors when under carport, which has ceiling but open on 2 sides.
Worse between 10 pm and 7am when all other external noises (e.g. traffic) are not or less present. Wakes me up middle of night when loudest between 2am and 3:30am and it's difficult to get back to sleep, if at all. Have heard it at other places I have visited. Within my very close group of family / acquaintances, which are about 13 people, only 3 can hear / sense it and 1 can only sense it.
During full moon phases it seems to be quieter in the early hours of the evening, but still loud in the middle of the night. When it rains it seems to be less intense or not present.
Just started hearing it in late August 2012, shortly after a drought and very hot temperatures in my area, so not sure if it is more prevalent during colder months until I get through a full year's cycle.

03/12/2012 06:57:16At nightIt is a low pitched rumbling tone around 80Hz. It does vary slightly in volume and pitch, much like a large diesel truck or locomotive idling off in the distance. The source of the hum is non-directional, it seems to come from everywhere. No, it never stops. Even during a recent region-wide power outage that lasted more than 24 hrs, the hum could still be heard.Around once per second on averageIn house upstairsWith great effort2011equally in both ears3-10 mileswithin 25 milesYesMore than 50 miles awayTerrain is predominantly wooded areas intermixed with open farmland, rolling hills and valleys, ~15 miles east of the the Hudson RiverRightMale52West Taghkanic, NYNoMy wife does not hear it 71-90 Hz

03/12/2012 13:58:04At nightVery subtle low frequency hum like a generator or diesel engine running in the distance. Seems to grow and wane in intensity over time (weeks / months). For example it sounds loud for several weeks or even months but then inexplicably reduces intensity for a few days or even a week or more beofre getting loud again.Over a period of 12 months I notice it seems to disappear or substantially reduce in intensity for a few days, or even up to a week a few times in the years for the last couple of years.

04/12/2012 08:21:05At nightA low reasonance hum that is not explainable. I thought was the extractor fan or tv/computer vibrating against the wall in the flat downstairs (I'm top floor in a block of 6). It's not constant - the description of a distant diesel lorry with engine problems is exactly right.

My whole bed seems to resonate with the noise and earplugs do nothing to help. Nobody else can hear it. It's not audible when I go to bed around 11pm, but by 2am every night I'm awake and being driven mad by it.
I only hear it from around 2am to 7am. I live near Heathrow airport so when the planes start flying around 5.30am it's a blessed relief. Most people complain about the plane noise, but not me!!

I've tried unplugging every electrical item in the flat - but to no avail. The sound doesn't seem audible outside.

NOT an electrical noise because the "power" company AND an electrical company have come to check the noise - which they could not hear. Sometimes it has the same sound you would get if you blew across a wide mouth bottle (do not misread that as a jar, but a bottle)NO! Sometimes it isn't as loud.

Some days its not so bad other times so loud I wonder why people aren't out on the streets shouting "what is that ?" !!I'm not sure ..there are times when its barely noticeable or even not there , though I try to minimise the quest for absolute silence as its one of my coping strategies.

06/12/2012 07:22:00At nightidling diesel engine would be the closest comparison. Sounds as if two frequencies are undulation. When it is very loud it feels as if there is pressure on my eardrums - similar to when you are driving in a car with one window cracked open but not as bad as that.We do not notice it in the summer months. Have turned off electric main to test that theory.
Outside ambient noise drowns it out I believe during the day which is why it is loudest at night.

06/12/2012 20:24:16Not surethis sound is felt as well as heard, and can change from sounding like a transformer attached to your house, a diesel train just sitting and idling right under your bedroom window, a combination of a ring along with sound of very loud bees swarming, or just the bee sound alone, or ring at all different levels alone. The diesel sound is very low and is felt so strongly that ice packs are needed on my head area. All these sounds carry a vibration, especially felt if in bed. Sometimes these different sounds can start up abruptly, go on for days at intolerable sound levels, and stop abruptly, only to start up again within a very short time period.
Weather definitely plays a part, and different phases of the moon or tides.
Aproximately 4 days before a full or new moon, the sounds and vibrations become louder, during it and about 2 days after.
These sounds can feel and sound like it fills the entire house.
Sometimes the buzzing sounds are so loud while driving, they actually override the highway sounds of trucks etc. going by.

Also have an eardrum that will not close up anymore;
(note, I have tried different noise cancellations including the latest Bose Headset, and cannot tell if they are turned on or off because this noise is so all permeating)
had auditory training twice, and finally purchased an Auditory Training set to have in my own home.....very little to no improvement.

ice packs around my head/temples and wearing my hearing aids on the 1st setting or phone setting works somewhat, along with several purifiers and fans going...my room sounds like a factory, and still at times when the sound is at its loudest, they cannot cover the extreme frequencies, whether high or low.

I seem to sleep better when the morning rush hours starts, as there is an all over white noise effect....up most nights, and cannot drive long without having to deal with the vibrations going through my whole body which is very tiring and drains me. I also feel blocked in the chest if drive is past 1/2 hour. This is partly due to other traffic noise, as driving back at night seems to work when there is little traffic on the road.
I have been constantly told I have Tinnitus, but this is much worse.

07/12/2012 11:01:58Same day and nightHas been constant low pitched humming sound since March/April 2012Not really although it does sometime dissipate during the day and over the last week (ie the first week in Dec 2012) the sound was very moderated for the first time since Mar/Apr 2012. Sometimes there are several momentary lulls (only seconds) during the early hours of the morning and then it starts again. Toady 8 December it is back with a vengeance. This sound can be heard by others and reports have been made by people over 50 kms away.

11/12/2012 14:08:48Same day and nightUsually a multiple low pitched sound that is an irregular throbbing hum that sounds like an idling engine or generator. Rarely a very loud vibrating hum, as if it were being generated by a large fleet of propeller aircraft, at high altitude, which doesn't move - I.E. no Doppler.The hum is becoming louder. I have not heard the hum turn off this year.Varies a lotIn house main floorWith great effort19991992equally in both earsNot sureNot sureNot sureless than 1 mileThe loudest that I've ever heard the hum was in 2005, on the mountains behind where I live in Marbella in Spain. It was so loud and clear that the non hearers that I was with could easily detect the sound. When I asked them to describe the noise they all responded in agreement, "It sounds like a large diesel engine idling in the distance". Also in 2007 on the North Shore in Auckland New Zealand, where I was sat at a large table which vibrated at the same frequency as the hum. I was able to feel the table vibrate through my fingers while simultaneously hearing the noise.
RightMale51I live with it.Since 1992 I have detected the hum in the following countries; Spain (Resident), United Kingdom, France, Germany, Switzerland, Italy, Czech Republic, Poland, Turkey, Morocco, Tunisia, Malta, Mallorca, Canary Islands, Singapore, Malaysia, Indonesia, Hong Kong, USA, New Zealand, Ireland.Tinnitus in my left ear since 1995, high pitched ringing whistle.Over the years I have kept notes on where I hear the hum, its different intensities, some facts that I have discovered, and what I think the possible cause is.

55
29/12/2012 08:56:21At nightA low frequency moaning with no repeating pattern for the most part. The diesel engine description fits only in the frequency, an engine would (does) have a more repeating sound. Like I stated above, it's intensity changes at times, through the 90's it was very loud at times and seemed to change intensity over weeks from very loud then less intensity each week until negligible, then reverse and gain intensity for weeks until very loud again. As stated above the hum seemed gone for a long while after 9/11/2001.....I thought something in me had changed and I couldn't hear it any longer. After hoping it be gone for years I actually sort of missed it. It's been heard by me since then (last night even) but never at the intensity of the late 1990's.

Below I will answer it's the upstairs where it's loudest but in actuality it's the same down stairs and inside a non running car but never outdoors.

It comes and goes, the intensity, at times off in the distance, others, like it's in the back yard of our house. Comes right out of the pillow at night, can't be heard outside.Very intense through the 90's, almost non existent for a few years after the 9/11 attacks.

02/01/2013 00:21:37At nightDescription of Sound: I started hearing it around 12/21/12 (ish) a Morse code like modulation of a subsonic hum. I as well can compare it to the "star wars series light sabers sound" (and I am not a Star Wars fan), except when they swung and or moved the sabers the tone changed (in the movie) / this sound or humming I perceive similar to that just without the change in tone, but instead a change or pulse like increase in volume or loudness (in my ear/head) and it sometimes feels like the air pressure is increasing and decreasing with these humming modulations. I can actually feel what seems like pressure in/on my eardrum/inner ear.
I as well for the first time this evening 1/1/13, upon arriving home heard the hum outside of my home in my driveway upon getting out of my car to enter my home. It was quite loud as well.
Prior I would go outside and hear nothing resembling the hum. Prior as well the hum was always the loudest in the upper levels of my home, like the bedrooms.

06/01/2013 02:09:03Same day and nightVery low frequency oscillating hum. It often reminds me of what a cell phone sounds like when placed near a speaker at just the ring angle. The start-stop oscillations of communicating with the cell tower is very similar. However, at times, it will be constant and steady for minutes at-a-time.

There is a fairly large high power complex about 3 miles from my home. When I stand in front of the cell towers, I can hear the hum but it is similar to in my home or standing outside of my home. So it seems inconclusive, even though the hum seems to mimic cellular activity. When I stand in front of the high power complex, the hum is deafening and feels as though it pulses against my eardrums. I can easily hear it over the sparking, crackling of the high tension power lines overhead.Villa Rica, GA, USA 30180All directions

06/01/2013 02:12:27At nightA deep throbbing rumble like an idling diesel engine. Until I heard about this phenomenon called "The Hum", I didn't realise that other people heard this too. I thought that maybe a truck driver somewhere in the valley was warming up his engine for ages. My husband doesn't hear anything, but it sometimes keeps me from sleeping. Often the sound is also a vibration sensation in my chest and stomach. It is stronger when my head is on the pillow on either side, not so strong when on my back.The sound is noticed sometimes when I try to sleep about midnight. On occasions it has stopped between half an hour and one hour later, as if an engine has been turned off. Other times it carries on until I go to sleep with some difficultyBetween once and twice per secondIn house upstairsWith some effort2006equally in both ears1-2 mileswithin 1 mileNot sure1 to 5 milesMy house is halfway up the hill in a long steep valley, in a country and city on seismic faultlines.

09/01/2013 22:07:37Same day and nightThe hum is omnidirectional and definitely external as I can hear other sounds as well (ie: tv, birds, wind, people talking etc, if it was tinnitus my hearing would be blocked and I wouldn't hear other ambient sounds), it sounds like an idling diesel engine or helicopter is in the near distance and differs in intensity or 'volume'. Volume not in the sense of sound waves per se, but as in a vibrational frequency. I can cover my ears and put the pillow over my head but it makes no difference. The ELF is amplified inside the house but I can still detect it outside the house. As of today, 10 Jan 2013, I have been hearing the hum since early Feb 2011. I have been recording the times and dates of hearing the hum since March 2011. It used to come and go randomly with no pattern, either for a few days only late at night or a few weeks late at night but for the past four weeks it has been almost continuous day and night with varying levels of intensity. It isn't stopping, hence my motivation to go online yet again to research it and I found your website.Steady tone/humIn house main floorWith great effort2011Feb 2011equally in both ears11-50 milesNot sureYesless than 1 mileAuckland is sitting on an Isthmus - meaning we are a harbour city, on a narrow neck of the main North Island where it is a short distance between the west and east coasts.RightFemale41Sleep disturbances, dizziness when very intenseNo.I have racked my brains trying to figure out the source/cause of the ELF. These are my options:
1. Volcanic activity (NZ has a lot of volcanoes either active, reawakening or dormant)
2. Electromagnetic Pollution (the hum has been so random with no pattern and quiet for extended periods of time that I have more or less ruled this out)
3. Man made radar or related type technology that has not been made public. For example HAARP etc, black technology being used. I have researched this and there are many 'Research' projects which makes this the most likely scenario. Possibly the following 'AARDDVARK' project?

The Antarctic-Arctic Radiation-belt (Dynamic) Deposition - VLF Atmospheric Research Konsortium (AARDDVARK) provides continuous long-range observations of the lower-ionosphere. The Konsortia sensors detect changes in ionisation levels from ~30-85 km altitude, with the goal of increasing the understanding of energy coupling between the Earth's atmosphere, Sun, and Space. We use the upper atmosphere as a gigantic energetic particle detector to observe and understand changing energy flows; this Science area impacts our knowledge of global change, communications, and navigation. The joint NZ-UK Antarctic-Arctic Radiation-belt (Dynamic) Deposition - VLF Atmospheric Research Konsortia (AARDDVARK) is a new extension of a well-establish experimental technique, allowing long-range probing of ionisation changes at comparatively low altitudes. Most other instruments which can probe the same altitudes are limited to essentially overhead measurements. At this stage AARDDVARK is essentially unique, as similar systems are only deployed at a regional level.

No.I believe this HUM is government related. They are using Extremely Low Frequency (ELF) for experiments and communication.

ELF radio waves are generated by lightning and natural disturbances in Earth's magnetic field, so they are a subject of research by atmospheric scientists. Because of the difficulty of building transmitters that can generate such long waves, ELF frequencies have been used in only a very few manmade communication systems. ELF waves can penetrate seawater to a depth of several hundred feet, so the US and Russian military have used ELF transmission facilities to communicate with their submerged submarines. The frequency of alternating current flowing in electric power grids, 50 or 60 Hz, falls within this frequency band, and power grids are an unintentional source of ELF radiation.

HAARP is a scientific endeavor aimed at studying the properties and behavior of the ionosphere, with particular emphasis on being able to understand and use it to enhance communications and surveillance systems for both civilian and defense purposes.

21/01/2013 17:45:53Same day and nightI have been referring to this sound as a bass noise. It sounds as though the neighbors have their bass cranked up. It typically follows a mmmmmm mmm mmm mmmmmmm pattern. It can become so loud that it resonates through my ears. I first noticed it at home but have also noticed the hum at work. For instance today I had to just leave because it was just that loud, and NOBODY could hear it. It's ironic that something could be so unbelievably loud to one person and another can't even hear it. I thought I was going nuts! I usually only hear it at work after my students have left for the day (I am a teacher). During the school day I must be too busy and with the hustle and bustle of the students I do not notice it. At home I must run a fan to block out the noise.The hum is at complete random.
