Advice on finding the cause of unknown (electrical?) buzzing sound? « on: December 07, 2020, 01:13:25 PM » Author: HPS_250
I am not sure if this sound is electrical, or if it is caused by something else such as vibration. Today is very windy, so it could possibly be caused by some kind of vibration. Coming from the wall between my laundry room and living room, there is a slight buzzing sound. The only electrical items nearby are an outlet and a switch box. There are some electronics on the table/cabinet next to the wall, including a TV (turned off), subwoofer, and WiFi router. I will check later if the sound goes away upon unplugging anything. Does anyone have advice on finding the cause of this sound?

I’ve always been interested in all kinds of lighting, mainly incandescent and HID, and especially all kinds of sodium lamps (HPS/LPS). I’ll tolerate LED but I’m not a fan of it.
I’m not proud to say that my city has Devolved to LED.

You're going about it in the correct way.  Unplug everything and plug them back in one by one until the humming starts up again. If it's still there after unplugging everything a more in-depth investigation will be needed.

I’ll report back if I find out the cause of it.

No problem, I like to help when I can, in between introducing some levity onto the site.

Does this buzzing produce a mains hum such as a 60hz hum in your case?

It sounds like a mains hum or 60Hz hum as far as I can tell, because it is not loud or high-pitched. There was another high-pitched hum in the same area, which turned out to be the TV power supply.

I have a switch (used in kitchen to disconnect power to the stove), which tends to make noise even when the stove is off. It is no sparking, just probably something like piezoelectricity in the bakelite (base material for holding tge contacts). So if unplugging things wont lead to anything conclusive, you may try to shut down the breakers of all the circuits around, one by one.
