室内扩散声场的Monte　Carlo模拟方法

The Monte Carlo method for simulating diffuse sound field

本文介绍了ＭｏｎｔｅＣａｒｌｏ方法模拟室内扩散声场的原理，模拟计算了混响室声场中的能量密度衰减曲线、能量脉冲响应、平均自由程及吸声系数等。该方法原理简单，占用内存少，适应于模拟室内声场分布。

This paper reviews the principles of the Monte Carlo method for simulating the diffuse sound field and presents some results of the diffuse sound field in reverberation room, such as energy density decay function, energy impulse response, mean free path and absorption coefficient. This method due to the advantage of simplicity in principle and less memory fits for computing the sound distribution in a room.
