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?

I have tennis and can still hear the noise. It’s weird. I have that background noise but I can still separate it from the other sounds around me. I actually went to do an audio test recently and had perfect hearing except I that I also hear extra things. Annoying as hell.
