Zonal sound distribution |
摘要 |
<p>Prior art creation of zonal reproduction systems suffer from performance and computational difficulties. A novel approach based on a cost function to optimise the cancellation and the target energy over a range of incoming plane wave directions is introduced, producing a planar sound field without explicitly specifying the propagation direction. The method produces consistent high contrast and a consistently planar target sound zone across the frequency range 80-7,000Hz.</p> |
