In this paper, a speaker array system based on equalization method is proposed to form a sound spot under room reverberant environment. It is well known that the conventional beamforming methods provide poor sound quality to users in reverberant environment. The proposed method reproduces sound as close as possible to the original source at target point and makes the nulls at the desired point located in the quiet zone. Simulation results with 16-channel speaker array system in the reverberant environment confirm that the sound pressure level in quiet zone depends on the number and the area of quiet points.
