AB  - In this paper a novel approach for sound field reproduction and multi-zone sound field control in a reverberant room is proposed. Sound field reproduction and multi-zone sound field control are jointly formulated as an optimization problem. The optimization problem relies on a physical model of the room acoustics which is computed numerically using the finite difference time domain (FDTD) method. Furthermore a novel regularization of the optimization problem is proposed. A non-convex sparsity-inducing term is used to obtain convenient control source positions and control source signals simultaneously. Finally, simulation results are presented: the proposed method is used to recreate an anechoic sound in a highly reverberant room while keeping part of the room silent.
