I remember seeing a news spot a few years ago about some company designing
ear protection devices which used destructive interference to cancel out
loud noises.
Although it would be near impossibly complex problem to solve. It'd be
pretty damn cool if you could build a device which would use destructive
interference to completely negate the sound output from a nearby
automobile stereo system.
It would of course be controlled using a 6502 based 8-bit micro to be on
topic for the list.
