摘要
阐述了在普通房间声干扰环境中观测声行波全部特性的一种设计，这种设计既能生动地看到声波的时空图象又能进行达到验证理论公式精度的测量．
A deaign is presented for observing and measuring the characteristics of travellingsound waves in common rooms with noise interference. Pictures of travelling waves can be displayedand the accuracy of theoretical formulae can be verified by using this design.
