Ran across this--
From issue 2533 of New Scientist magazine, 07 January 2006, page 19
Buzzing buttons cancel car noise
"DOZENS of vibrating buttons dotted around cars could give passengers a quieter ride. Attached to components around the vehicle, the coin-sized buttons will cancel out the vibrations that cause much of the noise inside a typical car.
Each button contains an accelerometer that detects the vibration frequency of the component it is attached to, plus a controller unit and a piezoelectric actuator. Software algorithms built into the controller calculate the frequency necessary to dampen the vibration. The controller then applies a voltage of this frequency to the actuator.
A research team, led by Arthur Berkhoff at the Dutch research organisation TNO, has already built the sensor and actuator. The next step is to miniaturise the circuitry without it overheating..."
Now I can think of some places to use these guys! Since it uses technology that was pioneered in the noise cancelling headsets, I can imagine a quieter world in the very near future.

Better still, can it be connected to the tv's audio output and configured to
eliminate a specific voice in the same room? Call it selective mute?
OOOPS!
