  • Abstract
    A method to generate superdirective beamforming using a microphone array and planar reflector is proposed. In this method, the beam width is reduced by positioning a reflector near the array and fixing the position of each microphone. Experimental results confirmed that the beam width was narrowed using the proposed method to half that with the conventional method.
