Along the topic of active suspension...
I saw a show on the Discovery channel, or The Learning Channel (or
some such cable channel) the had an "article" about Lotus's Active
sound canceling system. The system used sensors placed around the
interior of the car to "listen" to the noise, then cancel the noise
(engine sounds, air conditioner, etc.) by generating more "noise" 180
degrees out of phase. The system was designed to eliminate the buzz of
small 2, 3, or 4 cylinder econo box cars and engines; -- to make them
more acceptable.
>> I have also read about this technology being used
for "electronic mufflers" that can cancel out
the exhaust note. The environmental benefits are
obvious, but the notion of a silent supercar (or any
car really) is not only aesthetically odd, it's
downright eerie (at least to me !).
If Redcar didn't make the sound she does whilst
being rung out, she wouldn't be nearly as much fun to
fling .... ;-)
