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?

    I used to hear tv tubes, power supplies and all sorts of high frequency noise. These days I mostly just hear tinnitus. EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
