摘　　要：本文以惠威中国消音室为案例,研究了三维长方体空间内驻波方程及对应空间的频率条件,用Matlab模拟驻波图样并计算出人的听觉范围内所有能产生驻波的频率值,为室内声学和虚拟声学研究提供了参考指标.Based on a case of HiVi＇s sound-testing room, the equation for standing wave and the condition of frequency in a three dimensional space have been studied. The simulation of standing wave with Matlab and all the frequencies within human＇s hearing range have been presented which provide an index for room and virtual acoustics.
