Abstract

In this paper, we describe a sound reproduction method by using a linear front loudspeaker array. Sound images are reproduced by two processes separately on the basis of wave field synthesis. First, the front sound images are synthesized as plane waves. Second, the lateral or rear sound images are rendered by focused sources and reflected by side walls. To widen the listening area, a linear loudspeaker array system with steered directivity is proposed, providing the convenience of installation with a display device. Computational simulations are conducted to evaluate the proposed system.
