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 19):
The system as claimed in  claim 18 , wherein the filter controller is configured to execute at least one update procedure from the group consisting of:\n a stability condition based on the magnitude of the noise control filter transfer function, the stability condition being configured to prevent the loudspeaker from overdrive; and update the transfer characteristics of the finite impulse response filters, the update procedure being normalized to at least one reference noise signal representative of noise from at least one noise source.
