Oh... no, not really. I mean, sound vibrations are really, *really* 
tiny. (Think about it; even when the sound is turned up painfully loud, 
the speaker cones move by such a tiny amount you can't even see them 
move at all!)

AFAIK, the reason we have 200 W amplifiers and speakers isn't so much 
because it takes that much electricity to move air around, but to reduce 
RF pickup in the speaker wire... (Or rather, to reduce the 
*signifigance* of such pickup.)

The mater claims 249.98 V.

Also, 49.97 Hz. (So much for "they keep it to exactly 50 Hz to help all 
those clocks that use it". The frequency waivers all over the place!)
