声波波动特性的实验研究

Study on Characteristics of Acoustic Wave by the Oscillation

基于声速测试实验仪,从实验的角度研究了声波的干涉、衍射和反射特性,同时又借助于声波的干涉、衍射及反射原理测量了声波在空气中的传播速度。一方面加深了对声波波动特性的理解,另一方面提供了多种测量声速的实验方法,丰富了实验内容,同时也拓展了声速测试实验仪的使用。

This thesis is based on the speed of sound testing experimental instrument to measure the propagation ve- locity of sound in the air, as well as by means of acoustic interference, diffraction and reflection principle. The ex- perimental research on the one hand deepens the understanding of the acoustic wave characteristics, on the other hand provides a variety of measuring the speed of sound experimental methods, enriches the experiment content, but also to expand the use of the speed of sound testing experimental instrument.
