Abstract

In this paper, we propose a novel approach to multizone sound
reproduction, which is motivated by the Kirchhoff-Helmholtz integral
equation and aims at the simultaneous optimization of the sound pressure
and particle velocity vector on contours around multiple local
listening areas. The benefit of this approach is that the control points
do not need to be distributed within the local listening areas, as is
typically the case for previous multipoint approaches, but on
surrounding contours only. This is especially desirable when it comes to
practical realizations using real microphones as control points. A
closed-form solution is presented for determining the loudspeaker
weights in the frequency domain, and the effectiveness of the proposed
method, which we refer to as Joint Pressure and Velocity Matching
(JPVM), is validated by simulation results.
