Multizone 2D Soundfield Reproduction via Spatial Band Stop Filters

Wu, Yan (Jennifer); Abhayapala, Thushara


Any attempt to create multiple independent soundfields in separate zones over an extended region of open space results in unintended interference in a given zones from other zones. In this paper, we design spatial band stop filters to suppress interzone interference in the regions of interests and pass the desired soundfields with no distortion. This is achieved by using the higher order spatial harmonics of one zone to cancel the undesirable effects of the lower order harmonics of the same...[Show more]
