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?

Just checking that you know the tinnitus trick: palm flat on ear blocking sound, fingers drumming lightly on the back of your head.

Makes it go away fairly quickly for most people. Obviously isn't a permanent fix but helps when it gets annoying.

Yup! It fades it out really quick, but it comes back within minutes. My tinnitus has gotten a lot better lately.
