可闻声速测定仪的设计与制作

Design and Manufacture of Audible Sound Velocity Tester

可闻声速测定仪是以可闻声音作为声源,和原有的超声波声源声速测定仪相比,实验更加形象逼真。可闻声速测定仪所选用的元件和材料都是实验室常备的,并且该测定仪的结构简单易于制作,利用该测定仪测量的声速误差较小。

Based on audible sound as acoustic source,this design and manufacturing device can create much more lifelike effect in experiment when comparing with that of ultrasonic sound velocity tester.What＇s more,what the components and materials this device applies is very common stuff which is what permanent stores in laboratory;and the third advantage of the device is its simple structure which is easy formaking;and still one and the last advantage,that is,its experimental value shows less errors.
