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?
Oh no I was so looking forward to just a little bit of hearing loss to finally stop hearing all these noises around me :-(
You will lose the high pitch whine, but you might trade it for more mains hum (60/50hz)
