Abstract

A joint optimization of sound pressure and particle velocity method has been recently proposed for personal sound zone control, which demonstrates promising performance in terms of reproducing perceptually relevant sound field intensity in the bright zone and reducing the sound pressure in the dark zone. However, this joint optimization method requires a long control filter for the fullband control in reverberant room environments. To make the method suitable for real-time applications, we present in this paper a subband approach to the generation of personal sound zones by joint control of the sound pressure and particle velocity. We show that with the subband filtering strategy, the control filter is shortened so that the computational complexity is reduced. Numerical results demonstrate the superiority and effectiveness of the proposed subband method in comparison with the traditional fullband approach.
