Abstract

The creation of sound zones has been an active research topic for approximately two decades. Many sound zone control methods have been proposed, and the best approaches result in a target to interferer ratio (TIR) of about 15 dB in a practical set-up. Unfortunately, this is far from a TIR of about 25 dB which is currently believed necessary to make sound zones commercially viable. However, state-of-the-art sound zone control methods take neither the input signal characteristics nor human auditory perception into account. In this paper, we show how a recently proposed sound zone control framework called VAST can be extended into perceptual VAST (P-VAST) which takes input signal characteristics and human auditory perception into account. We also make a proof-of-concept simulation and an AB preference test which both show that P-VAST outperforms traditional sound zone control methods in terms of perceptually meaningful metrics such as STOI and PESQ in a fairly simple set-up.
