| Abstract(in English) | In this paper, we propose an improving method of the convergence speed in the sound reproduction system using the simultaneous perturbation method. In sound reproduction using loudspeakers, the preprocessing filters must be constituted to remove the influence of transfer functions between loudspeakers and control points and crosstalk paths. In the conventional sound reproduction system, however, the reproduced sound is degraded by movements of control points. Although the problem is solved by using the simultaneous perturbation method, this system suffers from the disadvantage of slow convergence. Therefore, we propose an improving method of the convergence speed with the delay control filters which compensate only the delay of the preprocessing filters before and after the movements. We also propose a method which considers distance decay of sound pressure due to the movements. Simulation results demonstrate that the proposed methods can realize reasonable convergence speed. |
