A Mystery Explained!

I've always wondered why I can hear a TV when it's on, whether there's any volume or not--there's this high-frequency noise they emit that very few people I've talked to can hear, and it drives me nuts. So I was reading the comments for a Slashdot article and discovered this:

It's the flyback transformer in your set making that noise - a very loud 15.75 KHz tone. I'm almost 40 years old and haven't taken real good care of my hearing, and it still bugs the hell out of me. One solution to the noise problem is to get a non-CRT television set (plasma, LCD, DLP, etc.).

Interesting stuff. I have no idea what a flyback transformer is, but I guess this is just another reason to justify the eventual purchase of a ridiculous television. (yay)
