In this paper, we propose a novel sound field reproduction system using the simultaneous perturbation (SP) method and its fast convergence version. In the conventional sound re- production systems, the preprocessing filters are generally determined and fixed based on transfer functions from loud- speakers to control points in advance. However, movements of control points result in severe localization errors. There- fore, we propose a sound field reproduction system using the SP method which updates the filter coefficients only using er- ror signal. The SP method suffers from the disadvantage of slow convergence, although this method can track the move- ments of any controlling points. Hence, we also propose an improving method of the convergence speed, which compen- sates only the delay by using the delay control filters. Sim- ulation results demonstrate that the proposed methods can track the movements of control points and have reasonable convergence speed. |
