摘要
A sound reinforcement system includes several microphones, a microphone beamformer coupled to the microphones, adaptive echo compensator (EC) coupled to the microphone beamformer for generating an echo compensated microphone signal, and several loudspeakers coupled to the adaptive EC. An adaptive loudspeaker beamformer is coupled between the adaptive EC and the loudspeakers for shaping the directional pattern of the loudspeakers. The adaptive loudspeaker beamformer creates a beam pattern which is capable of creating a “null” in the direction of speaker(s) such that howling is effectively prevented.
