Disney - have you reported the "hum" you experience to the City?

The Hum sound I experience does have "harmonics" in it, metallic tones - which makes me think it's pipes that are vibrating (versus electrical current) - though I think it is something EXTERNAL to the house causing the pipes to vibrate. I can feel the vibration most intrusively from about 3pm to at least midnight, but I experience it 24/7 (so far).

At 2:53pm this afternoon (aSunday), the vibration seemed to intensify quite a bit, and just now - at 10:40pm - it seemed to kick down just one grade, maybe.

Most of our public employees - as well as private contractors, etc. - don't work evenings, nights or early mornings -- which severely hampers any real investigation of this thing. The one public works employee who came to my home very early in the morning did feel the vibration - he said it felt sort of like his foot was falling asleep. Yep - that's it.

The more residents that bring this to the attention of City Officials, the better...

Have you had word back from the city? How many neighbors are affected in your neighborhood? Since this seems to be a world wide problem each area should do its own investigation. If you get any answers let us know. Good luck, Tom

The City has told me it's not its problem - in the sense that they have ruled out the cause being from anything they are doing or working on. I was told that if this is caused by private industry or a homeowner, they can't intervene -- unless laws are being broken.

So far I only have one other neighbor who has complained, but I recently learned that another resident several block away has made some inquiries with a contractor that I know. Now yet another other person has written a thread here.

Little by little, I hope to triangulate to the source - while I am simultaneously trying to rule out any possible cause originating from my own home or property...

I live in Union City and started hearing the low frequency humming sound about a month ago. Just want you to know you aren't the only one hearing it. -Chiefy

I am in the Torrance Gardena area of California. I noticed a hum sound since November 2011 and still around today January. I am 4 stories up so I get a good window of city noise easily. Night time or low nearby traffic is when the hum is at its peak. The sound is a "hum-thump-hum-thump-hum-thump-hum" at around 2 thumps per second. Sounds very similar to a woofer from a distance of a car driving. There are a lot of cars that thump base around here so I thought it was just some idiot doing this in a nearby park all throughout the night. I walked around at night and seen no cars in the park and could not locate the sound source. Its very annoying and causes loss of sleep at night because it changes my heart rate and the sound is loud if nothing around is dampening it out. I have a fan and an air conditioner next to me on just to get some sleep. It does not help. Appliances on is the same as appliances off "hum-thump-hum-thump-hum-thump-hum".

Time to check with cities as to any construction for the past few months and underground construction. Been here for 7 years and never heard this at all. If its construction, I will live. But if its some dumb moron or some clandestine nefarious agenda, I am going to raise hell.

Here's one take on this subject. The Hum is a generic name for a series of phenomena involving a persistent and invasive low-frequency humming noise not audible to all people. Hums have been reported in various geographical locations. In some cases a source has been located. A Hum on the Big Island of Hawaii, typically related to volcanic action, is heard in locations dozens of miles apart. The Hum is most often described as sounding somewhat like a distant idling diesel engine. Typically, the Hum is difficult to detect with microphones, and its source and nature are hard to localize.

The Hum is sometimes prefixed with the name of a locality where the problem has been particularly publicized: e.g. the "Bristol Hum", the "Taos Hum", or the "Bondi Hum".[1]
So you aren't alone. Regards, Tom

I live in San Clemente and I am hearing a humming sound too... I hear it louder in my house, although I know it's not originating in my house, because I had all of the utilities companies come out and shut off service (electricity, gas, water). Has your father made any progress identifying what the source of the sound is?

First off, this sound has nothing to do with your house and it is refered to as "The Hum."

I live in San Clemente Ca and my dad hears "The Hum" every night when it's really quiet... Really strange. I've looked into it and found that it actually made be caused by the earth itself. Check out this page about this phenomenon and Google "The Hum."

It talks about what you are experiencing exactly. People seem to feel this noise. Kinda creepy actually.

Hope this helps.

You are experiencing the noise known as "The Hum". If you've read the other posts you know you aren't the only one. This is a world wide happening, (Google "The Hum")
No cause, let alone a cure has been found to date. Regards, Tom

I too have experienced a low frequency hum throughout my house. It was driving me nuts. My wife couldn't hear it, only me. I traced it down to my vent stack pipes on my roof. I put a couple of 90 degree elbows on each vent to turn the outlet toward the roof. The low droning hum went away. I'm not saying that this will fix the problem that you are having but, you might give it a try.
