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 just remembered that the Dell docking station I’m using makes a sound when it processes data. I can literally hear my mouse move.

    Don’t buy Dell.

      My Dell does that! If I load a large image, ‘squeal’! Bought it used though, and anytime someone sells something, there’s a reason they’re selling it.
