Abstract

We have developed the active control system for low frequency road noise in automobiles combined with an audio system. It is the first commercial application in the world. This system adopts feedback control in the front seats and feedforward control in the rear seat, furthermore a music compensation circuit is applied. So it reduces only the noise in the front seats about 10 dB without canceling out the music. As the result, it is comfortable to the passengers to listen to the music.
