Sound Zones: Scattering Study with Head and Torso Simulator
One application of multichannel reproduction systems is to create personal sound zones. The key requirement of this concept is the ability for the system to generate one or more spatially confined regions of silence simultaneously with a single region optimized in some sense. In this paper, a scattering study is presented for two different sound zoning algorithms, in order to investigate the influence of a scattering object in the optimized region. The performance degradation when introducing a simple spherical scatterer is compared to a more realistic geometry resembling the listener using Finite Element Method and evaluated against measurements made under anechoic conditions. The results show that the reduction in separation between zones due to the scatterer depends on the characteristics of the wave field.
