Abstract:
An apparatus and method are presented for an active noise control system with a selector mechanism to select an appropriate reference signal for an active noise control algorithm responsive to several noise sources, some of which generate may sounds intermittently.

Claim (Index 1):
A noise cancellation apparatus comprising:\n a plurality of reference input sensors arranged around a perimeter of a spatial zone, wherein the plurality of reference input sensors generate a plurality of reference input signals in response to one or more noise sound waves generated by one or more noise sources; a selection mechanism coupled to the plurality of reference input sensors and configured to provide a reference control signal based on one or more of the plurality of reference input signals; a control unit in communication with the selection mechanism; an error input sensor proximate to the spatial zone within the perimeter, wherein the error input sensor is in communication with the control unit; and an output control transducer in communication with the control unit, wherein the control unit is configured to execute an adaptive noise control algorithm in response to the reference control signal received from the selection mechanism and the error signal received from the error input sensor, and wherein the adaptive noise control algorithm generates an output control signal for the output control transducer to generate a control sound wave configured to destructively interfere with the noise sound waves when the noise sound waves enter the spatial zone.
