Does anyone know why a high-pitched whining noise comes from my room when I plug in electrical items to the power socket? Random sockets, random items, but the noise is quiet and very high like a ringing in the ears; and you can't tell which direction it's coming from.
I don't know anything about these things so just thought I'd ask and see if anyone does.

And no, it's not just normal electricity noises, it's damned annoying and only been happening a week or so.

Haha thanks but I'm quite sure it's not my ears since it starts when I plug things in. I'll ask someone else if they can hear it before I visit the doctor I think :)

it comes from the transformer or power supply of the device you have plugged in. sometimes it's normal, like for monitors & TVs other times it could be a fault.

One reason you hear a high pitched sound is harmonics caused by hysteresis or eddy currents in the circuit. The other could be arcing.
Arcing is a serious problem and will cause a fire.
You have some loose connections, most likely at your switch.
Turn your breaker off, and tighten the screws on the switch.
If this doesn't work you can tighten the connections at the panel. The ground bar wires (bare copper or green wires). The neutral bar (white) wires.
The wires at the breakers.
The service entrance wires on the main lugs. You will have to pull the meter to kill the power to the main lugs.
If you do not feel comfortable doing this call a qualified electrician.
Remember arcing is a serious problem and will cause a fire.

something causing interference in something else. <---- this is correct
the question is what. What you are hearing is a high frequency sound. I hear it in TV's... asking a friend if they hear it does not mean it doesn't exist. A lot of people can't hear high frequency sounds.
Unfortunately, I don't know how you can narrow it down. you can try walking around the house with a cordless phone (not a cell) and talking on it, if it gets staticy in a room you hear the sound, note where in the room the phone sounds the worst (they are very sensitive to high frequency power... think microwave)
micro's, tv's, flourescent, neon all emit these sounds... things with motors can, but it's a sign that it will break soon.
Good luck on your quest. Remember, you'r not looking for what's making the sound, you're looking for what makes the sound when another thing is on... so trying one thing at a time may not work. Just note what is on when you start hearing the sound...

Possible causes:
Loose bulb in light fixture
Florescent bulbs
fan out of balance
Try unplugging everything, then plug them in one at a time to see if you can find it. If after unplugging everything, you still hear it, call an electrician. It could be a problem with the wiring.

I had the same problem once and found that the noise was coming from one of the bedside lamps. A couple of days later the bulb went.

Can you confirm-- Does it only happen in one room, with any item, in any socket?? i.e. when you remove the plug the noise stops immediately?? What about in other rooms?

You have what they call dogs ears ie very sensitive and probably Very big
Noddy had a friend called big ears and he had the same problem
Just kidding

I'd suggest using the elimination technique.
Turn off the switches, note changes.
Swap which socket it's in, note changes.
Unplug certain items from it or extended accessories, note changes.

Either you need an electrician or you have tinnitus.
