Abstract: Wave field synthesis is a spatial sound field reproduction technique aiming at authentic reproduction of auditory scenes within the entire listening area. However, the reflection in the listening room interferes with the auralized wave field and may impair the spatial reproduction. This paper proposes an active compensation approach based on plane wave decomposition and multichannel inverse filtering with the sound pressure and pressure gradient measured on the closed curve surrounding the listening area. The experiment results have shown that the algorithm is effective on the entire listening area. In contrast to other conventional compensation algorithms, this boundary element method requires fewer measurement channels and the plane wave decomposition has sufficient ability to analyze the reproduced sound field.
