Abstract

Multizone soundfield reproduction with various potential applications has recently drawn attentions in acoustic signal processing. In this paper, we seek to recreate two or more distinct 2D soundfields simultaneously at different spatial regions using multiple loudspeaker arrays. The basic ideas from the cross-talk cancelation systems were applied to determine the loudspeaker weights by the Least Squares method. Simulation results demonstrate favorable performance.
