Electrical Wiring in the Home/High pitch electrical squeel
Hi. I hope you can help me with this as it is driving me crazy. In my laundry room in my basement I can hear a high pitch squeal in the one corner of the laundry room. It sounds like a hearing aid that is running out of batteries. It's not a consistent pitch it goes up and down louder and softer. I can't hear it outside, and as soon as you leave the room you can't hear it. The only thing electrical in the area is the drier and the AC unit outside, and where I hear the sound there technically isn't even anything plugged in there. What could be causing the feedback sound?
Turn off all of your breakers. If the sound is still there, then it is non-electrical. Perhaps a plumbing noise. If the sound goes away, turn the breakers on one a time to figure out what is causing it. Perhaps it is a duct pipe, which will make the noise when the furnace has power. Maybe it is a light ballast or a transformer.
