摘要
介绍了谱分法(SDM)驱动函数的有效简化方法。仿真在一个平面内SDM合成的声场和波场合成(WFS)的声场,具有相似的听觉场景,分析了声场幅度拟合范围在声场传播方向上的变化及幅度分布特性。
A simple method of driving function for the spectral division method (SDM) is described. The reproduced sound field by SDM and wave field synthesis (WFS) in a plane is simulated,which has simular sound field. The different antplitude fitting range and the amplitude distribution of sound field by SDM and WFS along propagating direction are analyzed.
