Well, Sony (and I'm sure others) makes a set of noise-cancelling headphones
that work remarkably well. They can't filter out background noises like a TV
in the distance, but they do a hell of a job on hums and engine noise. I
tried a friend's, and the refrigerator fell dead silent when I flipped them
on. He says he can't use them when he drives, because his car is
cantankerous, and he can't hear the engine to know if something is wrong
with it.

PS. I just realized that the friend in question, Jay, is on this list now.
So if there is interest, he can say more about them than I can.
