When I was about 17, I could hear the high voltage flyback transformer
whine in a televison set. If I remember correctly that is about 18khz,
and the technical book I was reading at the time said it was inaudible
to most people, but some with very good hearing would be able to hear
it. That was back in the 50's, I haven't listened for the sound
lately, and I am not sure if the transistorized ones are as loud as the
old tube type sets they had back then.
