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 used to hear this...back when I was in my 20s 😭
Same I used to be able to tell when my boss shorted his board by the sound of the power supply going into overregulation. Now it's just eeeeee all the time.
