摘要

利用Comsol Multiphysics软件，采用声学有限元法计算了实际房间的脉冲响应和声学参数。介绍了室内脉冲响应和声学参数的计算过程。计算得到的500Hz倍频范围内的声学参数与现场实测结果进行了比较。结果表明，有限元法是预测室内低频声学参数的有效工具。

Calculating room acoustic parameters by finite element method

Room impulse response and the acoustical parameters of an actual room were calculated with acoustics finite element method using Comsol Multiphysics software. The procedure of calculating room impulse response and acoustic parameters were introduced. The calculated acoustics parameters up to octave bands of 500Hz were then compared with the field measured results. The FEM is proved to be a useful tool to predict the room acoustic parameters in low frequency range.
