Do you often hear the ringing of switching power supplies and devices when you are in a quiet space?

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?

They said 10 khz not 10 hz
Whoops
Only two orders of magnitude, can you really blame them?
Isn’t it 3? 10 -> 100 -> 1.000 -> 10.000
