Abstract
This paper proposes an efficient speaker array system to spotlight a sound into a target position in a reverberant environment. The proposed method introduces a criterion of maximizing the energy of system response from each channel to the target position. Simulation results with a sixteen channel speaker array system prove that the performance of the proposed method improves that of the conventional method that uses a broadband beamformer in a reverberant environment.
