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?

    Graphics system usually. Back in the day I used to be able to tell where on the screen the cursor was from the pitch of the coil whine.

    I buy better hardware nowadays 😂
