[QUOTE="squeak9798, post: 1444141, member: 555320"] You guys are dumb-dumbs: [B]Driving-music heaven[/B] Some people spend more money on their car stereo than their home hi-fi. Unfortunately, passengers can upset the perfect balance of a car stereo by selfishly reflecting and absorbing sound inside the vehicle. So IBM researchers have come up with a dashboard computer to automatically cancel such distortions. To calibrate the system the driver sits in an empty car and manually adjusts the volume and tone to their taste. From then on, each time the car is started, the system sends test signals through all the speakers at inaudibly high and low frequencies. The sound quality is then tested for each seat using microphones hidden in the headrests. The overall balance is automatically adjusted to give passengers a good overall sound, while still ensuring that the driver gets the best possible stereo effect.
