Abstract
A system and method for providing assistive listening for a plurality of listeners in an environment including a plurality of acoustic sources. A microphone array in combination with an acoustic beamforming processor configured to receive the acoustic signals within the environment and to process the acoustic signals based upon a target location of an acoustic signal selected on a listener-controlled interface device to generate a steered beam pattern. The acoustic beamforming processor further configured to transmit the steered beam pattern to the listener-controlled interface device based on the target location selected. The listener-controlled interface device configured to provide the steered beam pattern to an ear-level transducer of a hearing-impaired listener.
