A few days ago I started getting a constant high-pitched buzzing noise in my living room. It is only happening in this room, nowhere else. I checked the room directly above and below and there's no noise.

I removed all the fuses thinking it was related to the power outlets, but its still there. I also unplugged the phone line from its outlet and the cable from the tv, both to no avail.

The noise seems to be louder near the outside wall, but its difficult for me to determine an exact spot. On the other side of the wall are the phone and cable boxes as well as the gas meter. From the outside I don't hear any noises in that area.

Before calling an electrician or the phone/cable co, is there a way for me determine the what is causing the noise?

thanks.

If you removed all of the fuses then there is no electric power in the house so the noise could not be electrical.

But do you have a sub-panel? And what kind of fuse panel. Some have several pull out block plus screw in fuse.

In most of those you need to pull out all of the blocks.

And it would be very rare to have anything in the cable or telephone connections that would make noise.

Now noise, specially high pitch noises, can really be hard to trace.

Do you have a wind turbine on the roof. I have had then make a noise that is very hard to trace.

its definitely not electrical and i don't have a wine turbine.

I turned off the main power switch and sound is still there. the only items still live would be phone and cable. it seems to be coming from the ceiling of the room near the outside wall, but its very difficult to pinpoint exactly. As previously mentioned there's no sound in the room above. the point of noise seems to be where the phone and cable lines are attached to the house from the pole. from there the lines go down to the phone/cable boxes. I tried unplugging the phone from the jack and cable from the tv but it made no difference.

I have my home phone through the cable company and have called them to come and check the lines. i'm thinking there's static or some other issue with the line.

In the meantime any other suggestions would be greatly appreciated.

thanks.

I serious doubt that it has anything to do with phone or cable. But there have been cases where ice deflector (this is usually between poles, not house drops) have hummed with just the right amount of wind.

It could be bees. It is not unknow for the they form a hive in a wall.

You said the outside gas meter was also located here.....Use a screwdriver between your ear and the gas meter and listen.......

They can make noise............

I'd check the water pipes also.....a water meter is notorious for making noise........but you indicated your sound was isolated to this room.......

"...measure once.....cut twice....throw that one away and cut a new one...."

In another forum some one had problems with noise that they traced to water lines.

turns out that it was a city pressure reducing valve out in a manhole.

After five days of this constant noise, 24 hours a day, its gone! I was cleaning the window on the adjoining outer wall and suddenly the noised stopped. I didn't see any flies, bees or other insects that would explain the situation. I've had house flies caught in curtains before and the sound in the room was nothing close to that. Very odd.

Thank you all for your advice!
