Apparently, I'm one of a very small number of people who notices the high-frequency sounds emitted by dim light bulbs and box TV sets. They drive me insane. It sounds kind of like tinnitus would. I distinctly remember having to get up late at night to go ask my dad to turn the TV off (in spite of the fact that he had the volume way low) because I could hear the noise nearly 3 rooms away. So far my cousin is the only other person I've ever heard actually complain about the same problem. Currently, I am sitting in a room hoping I won't have to change the light bulbs out... they're new bulbs, but that noise... eek.
