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?

I did not have the brain power to reply so thank you for doing it for me and all of those of us who find it too “normal” to try to answer this for the like 20th time.
