I'm curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

I can hear my phone charging.

Not after I stopped buying cheap power supplies.

My friends and I used to drive out to an area of the desert, away from people and the general noise of civilization. However, there were large power transmission lines going through the area and we could listen to them crackle in the night as we watched the stars. Just a nice way to relax and get away from it all.

  • 5-port USB hub
  • wireless charger

Thankfully none else!

I hear some of them. There's a real cheap one my parents got with a security camera thats real loud to me, but they don't hear it.

Yes, but a bit less as I've aged probably because the higher frequency hearing we have starts to diminish the older we get.

I did when I was younger but I don't hear it since I hit around 30

Since I got older this got better. One benefit I guess?
