Title: SYSTEM AND METHOD FOR NOISE CANCELLATION
Abstract:
Embodiments of the present invention provide a system (100) for a vehicle, the system comprising noise input means (110) for generating a noise signal (112, 114) indicative of noise, error sensing means (120) for generating an error signal (122, 124) indicative of a noise cancellation error at a location in the vehicle, proximity sensing means (130) for generating a signal indicative of an obstruction proximal to the error sensing means (120) and outputting a proximity signal (132, 134) in dependence thereon, and noise cancellation means (140) arranged to determine a noise cancellation signal (141) in dependence on the noise signal (112, 114), the error signal (122, 124) and the proximity signal, and to output the noise cancellation signal (141) to an audio output means for reducing noise in the vehicle.
