2.5D Multizone Reproduction with Active Control of Scattered Sound Fields

Zhang, Junqing; Zhang, Wen; Abhayapala, Thushara; Xie, Jingli; Zhang, Lijun


Multizone reproduction has been focused on reproducing sounds in an empty listening space. However, there are always scatterers such as human heads in sound zones, generating scattered sound fields and causing degraded system performance. In this work, we develop a modal-domain method for 2.5D multizone reproduction with a solid object in the bright zone. Analytical expressions of the incident and scattered fields are developed. We then propose an active control strategy to correct the...[Show more]
