Comment Hearing TV Whine (Score 2, Informative) 333
Being able to hear the TV is just a matter of having good (not alien, just good) hearing.
The scanline transducer operates 525 times per refresh, 30 times a second: 15.750khz. This is within the range of human hearing, so if a transducer is of poor quality, you can hear it.
My guess is that many people just don't pay attention to it, even though they can hear it.
However lots of people who grew up listening to Walkmans and other devices can't hear it, because they've destroyed their high-range hearing.
