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?

The TV thing, from what I've gathered, is normal in kids and lasts up until your 30s or somewhere around there. After that your ears just can't pick up that pitch anymore.

CRT TV's stopped being common at the same time I was aging into the range that would be unable to hear their distinctive whine.

I'm 40s and can pick it up sometimes. Depends on the TV.
