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 just remembered that the Dell docking station I’m using makes a sound when it processes data. I can literally hear my mouse move.

Don’t buy Dell.
