Do you often hear the ringing of switching power supplies and devices when you are in a quiet space? (lemmy.world)

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?

There's an app I use on my phone to turn mine off through Bluetooth as well. I noticed they will turn back on if the power ever goes out here so it's nice having the ability to turn them off without having to turn on my pc and go through steam.
