Low frequency tinnitis?

[Brandon B]

Is there such a thing. In my house at night, I hear a hum, similar in frequency to an AC compressor or refrigerator hum, even sort of changes intensity. But I cannot locate any possible source for the noise. Was wondering if it's me.

Anyone know if this happens, or is it always the high test tone type noise?

Cover your ears and see if you still hear it. If you still hear it it's in your head (or ears). If you don't still hear it, it's in your house--it could be as simple as a humming transformer in your clock radio, or something like that.

I tried covering my ears, and it SEEMS to make it go away, but it is fairly faint, so it's hard to be sure. I went out my front door, and can't hear it outside, but there is a little more ambient noise out there. Seems to indicate it is not a neighbor's AC unit or anything though, cuz it would get louder when I opened the door if so.

It is not my clock radio, I can hear it in different room and my clock radio is silent. I can't think of a single thing in the house that could cause it. I have eliminated:

Refrigerators
AC equipment
audio equipment
doorbell transformer
computers

I would think it was freeway noise, but it is a perfect constant pitch.

In fact, it sounds just like the HVAC system here at work. I'm not near any power lines. No big transformers near my house.

I'm at a loss. I really don't think it's in my head, but I can't conceive of a source.

Try turning off the main breaker and see if that stops the hum...if so you know its power related.

Even if you turn off your power it could be a neighbor's AC unit or something--sometimes it'll sound quite different inside than out so you don't recognize it. Especially if you're lying in bed on your side so one ear is covered, sometimes faint noises sound different and not as recognizable.
