Patent ID: 8077873

Claim:
An active noise control system comprising: a memory in communication with a processor; where the processor is configured to select a first speaker group from a plurality of speakers, where the first speaker group is selected to receive a corresponding anti-noise signal configured to drive the first speaker group to produce sound waves to destructively interfere with an undesired sound present in at least one quiet zone; the processor further configured to receive a first error signal, where the first error signal is representative of a combination of sound waves produced by the first speaker group and the undesired sound detected in the at least one quiet zone; the processor further configured to determine when a second speaker group different than the first speaker group is configured to produce a second error signal less than the first error signal, where the second error signal is representative of a combination of sound waves produced by the second speaker group and the undesired sound detected in the at least one quiet zone; and the processor further configured to replace the first speaker group with the second speaker group.
