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?

Not anymore.Age.

When I was a kid I hated going to the city art museum because all the humidity and temperature control devices emitted this awful high frequency noise that made me nauseated.

I can't hear the "mosquito" pitch noise emitters used to deter teenage loitering in some cities anymore. I kept that longer than I thought I would.

I had to throw out my carbon monoxide detectors. The constant beeping was giving me a head ache and making me nauseous.
