Constant "humming" noise.............

[Zeekiebuns]

Anyone have more info on the show that just aired (11/30/01) regarding the constant humming noise (engine noise)some people are hearing? Have had this problem the past 4 years. Numerous visits to "specialists" and tests, ended with the probability that it was just a muscle contracting in the neck. I believe it was a polite way of saying "we don't know". I was really shocked and relieved to find out there are others with this same problem and I am not "crazy". Would like to hear from other with this same phenomenen and how they cope. Thanks

I am in the Navy and I was stationed in Groton, CT for a time. A theory on this is that is comes from waves set off by Navy ships and Submarines. So if you live near a military base this might be the answer.

[nohwheregirl]

I did a little internet research on this a while back and found that there are quite a few websites dedicated to the "Taos Hum" and the "Kokomo Hum." These are 2 places in the U.S. that have been identified as having a concentration of people who hear the hum. You should be able to find a lot of info, and possibly some other sufferers if you google those terms.

I'm curious, would you mind giving us some more details on when you started hearing it, when you hear it, etc?

I know this thread is four years old :eek:, but I actually rewatched this segment recently. It's kind of one of those love-it-or-hate it segments and is not typically the sort I'm usually very interested in, but I've always found "the Hum" kind of fascinating since I first saw this segment as a kid.

In 2007 and 2008, I was sent to Ft. Lewis, Washington for training, for approximately a month each block. Both times I noticed a consistent mechanical drone, but nothing that affected me physically, as a lot of hearers claim. I'm unsure if I was hearing cooling fans of some sort or aircraft, but it WAS consistent and I could always hear it, although the intensity varied. It was worse indoors and hardly perceivable in deep woods (the latter of which I spent more time in). It also didn't really sound much like the reproduction clip in the segment, which to me sounds very electronic. It sounded exactly like a diesel truck idling in the distance.

Facts:

1. The immediate area in and around Tacoma, WA is home to three military installations: Ft. Lewis, McChord AFB, and FOB Tacoma (specifically Puget Sound).

2. There's always a gross amount of mechanical, electronic, and radio activity in any area near military installations.

3. The Kokomo Hum has since been nearly positively identified as the noise emitted from two cooling fans contained in a DaimlerChrysler plant near the city of Kokomo.

4. The American Southwest (which would include Taos, NM) is full of military activity--especially that of the Air Force and Army. Both require extensive communication systems as the range between two areas can be massive. Furthermore, large amounts of weapons testing occurs there. That also requires long-range radio and electronic signals.


My ex-boyfriend was also stationed at Groton, CT when he was in the Navy and was actually an electronic communications tech/specialist (whatever the Navy calls them) on the Miami, a fast attack submarine. The Navy doesn't use ELF anymore, and he said he never heard a thing. However, the majority of "hum hearers" in the U.S. seem to be concentrated around military installations.

Never, however, have I heard this hum anywhere but Ft. Lewis. I have spent time at Ft. Jackson, SC; Ft. Campbell, KY; Ft. Knox, KY; Ft. Benning, GA; Ft. MacPherson, GA; Ft. Bragg, NC, and Arnold AFB (TN). The main differences between these installations and Ft. Lewis is that they are all in the Southeast and have no extensive naval activity that I am aware of (unlike Lewis, which is directly beside Puget Sound). Not making any inferences here, just stating what I know.


I do believe the "hum" most people hear is military in nature, but I don't believe it's necessarily regulated to any one branch of the armed forces. I DO think it's related to commo and signaling systems, however. I do believe I've heard it and lots of others do as well, but are not so sensitive that it affects their daily lives, and thus never report it.

Great post MegtheEgg86. Well thought out and interesting to hear your perspective.

I did (and still do) side on the non-military origin of the sound. Taos, while as you note in the Southwest where much military activity occurs, is not near an obvious military "source". I understood the UM thoery to be that the hum was somehow connected to the ultra low frequency communications that the Navy used to contact submarines. Therefore, I would expect that people would be more affected around Naval installations (Norfolk, Pearl, Portsmouth).

My inclination is that it is a hearing "impediment" for lack of a better word. The ear is sensitive and some people who experience trauma have been know to suffer from various forms of "timber" or oscillating tones. It may be that there groups of such people who were able to connect w/ one another and speculate that there is a source where the sound is coming from.

Another possibility is that it is some heretofore undiscovered natural phenomenon. Taos, I believe having been there, possess an inherent spiritual / mystical presence. I know it sounds New Agey, but there are certain areas that may have properties that we simply cannot (at this point) scientifically analyze. I know that Tibetan Bhuddisim believes that the Earth has certain areas that possess human characteristics. For example, Los Angeles (I believe) is the voice - center of the Earth. I may be botching this concept, but I'm pretty sure I'm right.

We will likely never know the answer, military, natural, or otherwise.

I think this could be a good explanation for this mystery:

(from the Wikipedia)

"The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks induced by pulsed/modulated microwave frequencies. The clicks are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. These induced sounds are not audible to other people nearby.

The microwave auditory effect was later discovered to be inducible with shorter-wavelength portions of the electromagnetic spectrum. During the Cold War era, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish (Journal of Applied Physiology, Vol. 17, pages 689-692, 1962) information on the nature of the microwave auditory effect; this effect is therefore also known as the Frey effect.

Dr. Don R. Justesen published "Microwaves and Behavior" in The American Psychologist (Volume 30, March 1975, Number 3).

Research by NASA in the 1970s[citation needed] showed that this effect occurs as a result of thermal expansion of parts of the human ear around the cochlea, even at low power density.
Later, signal modulation was found to produce sounds or words that appeared to originate intracranially.

It was studied for its possible use in communications but has not been developed due to the possible hazardous biological effects of microwave radiation. Similar research conducted in the USSR studied its use in non-lethal weaponry."

I grew up about fourty miles away from Taos, NM. Still today there are some people that claim to hear the hum.

Thank you. I've wondered if I suffer from tinnitus as I've been exposed to very, very loud and sudden noise, and your post got me thinking.

Perhaps at least my personal experience at Ft. Lewis can be explained as I was repeatedly exposed to various small arms fire and artillery noise there. It traumatized my ears--causing the perceivable ringing without physical side effect--and ended soon after I returned home and away from the constant barrage of sound.

Perhaps being indoors effects the perceivability of the ringing in some way as well; maybe it's related to air pressure or something. I haven't a clue, though.

Interesting notion re: spiritual/mystical properties. I'm due to travel to the Southwest this December. I'll take note of anything I experience there.

[leafygreens]

I think it's tinnitus. Some are more susceptible than others.

:confused: I live just East of Fort Lewis/McChord AFB, and for the past several weeks I have been "hearing" an annoying low frequency/low volume "hum" or noise. Initially, I thought it was an appliance or ballast in the house that was going bad, but after shutting off power to the house, I then started emailing local Power co-op, Pierce County, and McChord Public Affairs people....I have heard back from my Power Co., and County watershed representatives, they cannot explain source of hum. McChord AFB Public Affairs rep is looking into it for me (I am retired Air Force).

That is when I started looking towards the internet for answers... and found this thread/forum. I too believe the hum is coming from the Military bases, but outside the house, direction/pinpointing source is very difficult. And, it seems strange, but wearing earplugs at night eliminates/reduces the "noise" for me:confused:

So, I will continue to research and look for source on this annoyance. I now stay at home (retired from 2nd career in Sep2012) and have the time and patience to search. I will travel away from this area (late at night) to see if noise follows me... More to come.

Thank you for your service, Artacoma, and thanks for posting. I'm interested to hear what you find out. The Hum has always fascinated me, but I don't like to watch the segment. I have this weird fear that I will start hearing it myself. :lol:

[Artacoma]

Thanks for your interest in this "phenomenon/mystery"...by the way, I have never seen the Unexplained Mysteries show about this "hum"...I found this forum through my internet search for answers. I am still hoping (and will search for) others who live in the area who also have experieced this "hum". "It" is not a big disruption or problem to me, but Now I am very curious as to what, where its from, and why it happens to only some (my wife and neighbor say they don't "hear" it)... Soo, after my initial investigations/tests, I am convinced that the "noise" IS real and not a form of Tinnitus because what I “hear” isn’t a ringing or steady tone, but it appears to be more “mechanical” as a slightly fluctuating/modulating motor sound, like a slightly out-of-tune engine. At night, the volume is about the same regardless if upstairs in the bedroom (where I initially experienced it at night) or in the storage closet in the center of downstairs basement of the house WITH all electrical circuit breakers shut-off.) Like I said before, with very good ear plugs (above an NRR rating of 33dB) I can almost block out "sound". Although, as one post above stated, the "Frey effect" could be an explanation (Microwave/Radiowave detection by certain individuals) I am not convinced because, like MegtheEgg86 posted, we haven't "heard" this "noise" at any other of the dozens of Military bases/posts that we have been stationed at??
I will start mapping/plotting a "volume/detection" distance grid as I travel east from McChord AFB (our home is only about a mile from main runway) to see how far out I can still detect this "noise". Sitting in my car while parked at McChord BX parking lot, I can detect it, but lower in volume and appears to more broken/modulated .....more to come.

Yes..me too. :lol:

I still think that guy in the segment had a weird shaped head,and that had something to do with it. :D

[Nickolas086]

interesting case

[danmanx]

I watched this case tonight. I think the wiki says it best. There is definitely something going on, but most people might be concentrating too much on listening more so than an average person.

I myself, tonight, was listening to background noise and I swore I heard the hum for about one hour and then it went away. Still though, I feel bad for anybody losing sleep or being uncomfortable over it.

And yes, it does sound like a diesel engine.

Here's my problem: There's diesel engines constantly filling up with gas across my street!

Strange I know!

[TheCars1986]

I agree with MegtheEgg86. I think it's something military related. I can't fathom how people have managed to live with it for years without going insane.

[Artacoma]

Here is an update on the HUM here at Ft Lewis/McChord...

I did drive up to the Canadian border last month and stopped along the way to see if this HUM followed. At the first few stops - still could detect the HUM. But at a rest stop in Arlington, just north of Seattle, NO HUM. And when I arrived at my destination in Blaine, Washington, just south of Canada, I couldn't 'hear' the HUM....but in the Morning the next day (still at Blaine, WA) I detected the HUM. So I scheduled an appointment for audiologist who tested my hearing (which was good), and set me up for an MRI. I have an appointment with the Neurologist in two weeks to go over the MRI results, but do NOT believe it will show anything...because, I recently returned from a week of sailing in the British Virgin Islands, where I NEVER detected/heard the HUM!?! But, as MEGTHEGG experienced, only when I returned to this area (McChord AFB/Ft. Lewis) do I again 'detect' the HUM - constantly, 24/7.

I am going to ask the physicians at Madigan Army Hospital next month (my neurologist appointment) if / how many others are 'hearing' the HUM......

[wiseguy182]

ho hum.

sorry, couldn't resist.

[Necco]

ho hum.

sorry, couldn't resist.

I guess you could call the hum a ho. It did get around. :happyface
