摘要
在一般测定声速的实验中，利用听觉很难辨别声波干涉形成的振动加强和减弱的变化。文章采用传感器和数据采集接口，利用计算机采集数据，配以专用DataStudio软件，用共振驻波法测量声波的波速，不仅可以听到声音强弱的变化，而且可通过计算机演示波形的变化。
It is hard to discern the change of sound oscillation with our hearing in general experiment for mensurating velocity of sound. The article adopts sensor, ScienceWorkshop to measure velocity of sound with syntony stationary wave method. Not only the change of sound wave can be heard, but also the change of sound wave with computer can be demonstrated.
