Abstract:
An active noise cancellation system and method, in which an active noise controller generates an anti-noise signal based on an error signal, and a loudspeaker operatively coupled to the active noise controller converts the anti-noise signal into anti-noise sound. An acoustic error sensor operatively coupled to the active noise controller picks up sound and converts the picked-up sound into the error signal. The acoustic error sensor is disposed at a front face of the loudspeaker.

Claim (Index 17):
The system of  claim 16 , wherein the loudspeaker is mounted to an exhaust system of a vehicle, the exhaust system being mechanically connected to an engine and comprising a catalyst, a center muffler and a rear muffler, the loudspeaker being mounted to the rear muffler, the system further comprises acoustic coupling of one or more reference sensors from the group consisting of; a first one of the reference sensors is acoustically coupled to the engine, a second one of the reference sensors is acoustically coupled to the exhaust system between the catalyst and the center muffler, and a third one of the reference sensors is acoustically coupled to the exhaust system between the center muffler and the rear muffler.
