Abstract
An audio system controls feedback when beamforming an output for production by transducers by generating a beamforming output signal based on audio from a first set and a second set of acoustic sensors. The first set may include acoustic sensors that may experience feedback from the transducers. The second set may exclude the acoustic sensors that cause feedback. The beamforming output from each set are combined as a weighted combination based on a beamforming coefficient that may be dynamically set to increase contribution of the first set until the combined output causes feedback, enabling the total beamforming output to benefit from a larger set of acoustic sensors while avoiding detrimental feedback. The interaural characteristics of the external environment may also be analyzed and the beamforming output modified to increase a difference in the interaural characteristic and thereby increase perception of the beamforming output.
