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?

Yes, often. It doesn't really bother me that much, plus tinnitus generally overwhelms those sounds.

My favorite is when the ringing from power resonates with the tinnitus and ends up with an oscillating tone. Drives me absolutely insane.

Great, just what I need: resonating tinnitus!

I've been trying some of the tinnitus masking videos from "Dale Snale". It's been hit and miss though, some of the frequencies closest to my own have actually made it worse! So I've been trying stuff further away from the 13KHz region.
