Ever wondered if you could cancel someones voice without the need for a physical wall or partition? In this work presented at ICASSP 2017 in New Orleans, USA, we investigate the possibilities of cancelling speech over a loudspeaker wall. The method is not limited to speech, in-fact, it works much better for periodic signals as the non-stationarity of speech degrades the performance.
A hybrid loudspeaker system consisting of dynamic point sources and parametric loudspeaker models shows great results above, generally inevitable, soundfield aliasing frequencies.
