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?

Yeah I don't even hear the big 40A power supplies at work, usually 3 or 4 of them in a row on din rail.
The variable frequency drives are a different story, sometimes those sound like the worst high frequency you've ever heard in your life. But I don't even hear those all the time anymore, depending on the drive.
I take steps to make sure my tinnitus isn't getting worse. But about all you can do is try and protect your ears as best as you can. Once it's there, it's there to stay
