Ok, I've had this problem a few times using this Acer Generic brand computer. But I've yet to put it to the test.

I hear a light humming noise when I'm using the computer, I have fairly sensitive ears. I just figured I was picking up some kind of electronic feedback.

So just now I said, damn that noise really ticks me off. So I closed my ears, hands over them. Continued hearing it, not as high of a level but heard it very clearly. Then I plugged my ears, and could still hear it.

Is it just because it's a high frequency noise? I am going to see if any of my accomplices can testify to hearing the noise as I do.

OK, maybe I am missing something here, your computer makes noise and...?

If your surroundings calm without any noise at all?

If so, then you might hear a humming sound due to the air moving inside the ear, this is similar to how, you hear a wind like sound when you hold a sea shell near your ears.

No no no no no no. It's only in the room with my computer.

It occurs as soon as the computer as turned on.

And I can hear it with my ears plugged, like it's in my head.

Ok, if you are sure that it is from your computer, then touch the CPU and see if it is vibrating with very high frequency.

I'd check out whats inside make sure everything is in proper order fans, wires nothing touching the motherboard that isn't supposed to or ask an expert to look at it but chances are that's the sound it will always make, unless it's just a noisy fan, or noisy cd/dvd player? my computer has 2 fans, well 3 fans and it's as loud as a car from 100ft away at all times, it's common.

Wait until you start making out talking....you are in for a ride, buckle up.

Do you live under power lines?
Do you have any hearing damage?
Do you trim your ear hair (inside canal)?

Fans are the worst....be careful. You start making out words or music...anything that isn't normal. Put ear plugs in immediately and do not listen any more for the sounds. That is my advice...best of luck.

Really it just depends on the wave pattern of the sound extreme wave patterns one way or the other can easily pass through solid objects.

Take a bass speaker for example if you have the right equipment and you produce a low frequency well I'll give you an example might be easier to understand.

I had a car with a huge speaker in it to produce bass. The speaker took up the entire hatch back portion of my car and used the back portion of the hatch back as a box built around the sub woofer.

Had crazy bass and one day I pull up to the gas station and left the car running and ran in.

When I left the car barely any noticeable bass only thing I noticed was the car frame was vibrating.

However when going into the gas station I could hear my bass as if I was still in my car. The waves were leaving the car and hitting the gas stations windows and after passing through the windows the sound became hear-able again.

It has a lot to do with waves length, strength, reverberation, etc.

So basically what is happening is quite normal but it can be very annoying depending on the waves intensity and the length or lack of. If it is caused by something mechanical you can't change it without changing the mechanic causing it. Therefor if you can narrow it down to 1 thing you should just be able to replace it for relatively cheap. If it's actually coming from something electronic like a circuit board, although I've never personally seen that happen, that could potentially be a bad sign.

Argh!!!

New problem has arose.

Last night after being on the computer for a substantial amount of time, and turning the computer off, the sound persisted?

And when I woke up it was gone... Now it's back.

I think they're sending cancerous waves into my brain....

I hear a similar sound as the one in the link and I thought it was cuz I'm pregnant and the baby was bumping some nerve in my back. But if other people are hearing it too then maybe there's something wrong. How do I get rid of it? And is it harmful?
It's giving me a headache and I hear it all throughout my apartment even with ear plugs. Only in one ear though.
