Hum Sound in House

wrote:

If the hum has an audio frequency similar to a cheap vibration type aquarium air pump or to a mains powered vibration massager then your hum has something (equipment, waterpipes) to do with the 60 hertz mains power supply.

I have the same thing, I've lived here for 10 years now and we have it mainly upstairs but if the house is quiet, I can hear it, it sounds like a transformer for something though I can't think of what unless the smoke detectors in this house have one, that's all I can think of.In my case anyway.

Turn off the main breaker to see if it is electrical and stops. If it stops locate it by shutting down one circut at a time . Or look up Taos Hum, and go into the Twilite Zone

Had the same problem. Took six months to solve. Sounded like a 60 cycle hum, blamed something electrical. Finally gave up blaming electrical stuff after a blackout and I still had a hum that came and went with the power off. Found it to be a bad gas meter. It hummed when gas equipment was running and transmitted the sound through the gas pipes. Gas company changed the meter.

Very good point. If you shut everything down at the service entrance when you heat it, and it continues, you would rule out all the electrical things. Then I guess you could try shutting off the water.

hum,
after
and
meter.
We had a similar problem with a intermittant squeaking you could hear throughout the house. It was also a bad gas meter.

When I moved into my house my water meter made a intermittent squeaking noise when there was a draw. The meter was changed and the problem fixed.

Eric, After reading your response, I phoned the gas company. They sent a person out to the house who checked the gas meter (it was OK), and at my request, checked my fairly new furnace. Said the furnace was working fine and not causing the hum. Was told the hum sounded electrical. Haven't been able to pin point it yet. Al

So have you turned off each breaker at a time or not?

I have a hum in the hallway. It is a 60 cycle hum from an 120V transformer for the smoke detector. I haven't had time to replace it with a battery operated one. It has to be very quite before I notice it.

There are many possible sources. My problem is usually the clock on the stove.
Anything using AC power, connected to some distribution (heating, water or sewer) system is a good suspect.

Check your toilet tank. Next time you hear the hum pull up on the ball float to shut of the water valve. IF noise goes away, case closed. Otherwise I'd kill the power to the house to see if it's electrical in nature.
Seriuosly, my house used to have a hum that came and went and I could not localize it. It was a leaky flapper valve in the toilet causing the float valve to open just a smidgen and setting up standing waves in the pipes.

I also hear a hum at times. Seems to happen mostly in the cold when the house is sealed up. Dosent sound like 60HZ though. It sometimes also may have like a throbbing or rolling type of effect. I have another problem, I'm the only one that can hear it. My wife and 2 kids dont hear it. I can hear it lying in bed or sittng downstairs in the Familyroom. AT one point it sound mostly like from the left ear only.It kept we awake at nights also. I saw a hearing specialists and had all kinds of tests done. He even did a pressure tests. I thought he was gonna blow my head up. He thought cause of my age he was gonna find hearing loss but did not.Shit I could have told him that since I'm hearing shit no one else does. He then told me it could be from drinking too much coffee, yeah no shit , he really said that. He then said it may be Tinitus. Well anyway then it went away for almost a year. Now it comes back. One week I may hear it and one week I may not.

Why don't you turn every breaker in your house off and see if you can still hear it. If you can, it's doubtful it's coming from in the house! If you can't hear it anymore, turn on a breaker at a time to isolate it to a particular circuit. Could be a transformer, TV, lots of things.

says...

I'll support the two main things that have been suggested here:
1. When the noise is going on, flip the main circuit breaker. If it's electrical, that will kill it and you'll know to hunt it down.
2. In my case, it was a pipe hum ("foghorn") caused by a "bad" toilet fill valve and exacerbated by a leaking flapper (so, the toilet leaked and the fill valve got a lot more use). The noise was uncanny (loud foghorn!!) and NOT repeat NOT centered at the toilet. But, shutting down the toilet's water supply cutoff reproducibly stopped the noise.
I replaced the ballcock fill valve and the noise was exorcised.
