Determination of the velocity of sound based on the ultrasonic wave interference by a fitting method and the analysis of corresponding error

ZHOU Tian-ci,CHEN Shui-qiao(Department of Physics,Zhejiang University,Hangzhou 310027,China)  
By the analysis of ultrasonic wave interference pattern,a fitting method was designed through mathematical derivation to determine the velocity of sound.With the help of a software called Cassy Lab and other devices to record the intensity of ultrasonic wave interference in a horizontal plane(i.e.the interference pattern),the velocity of sound was obtained by the specialized software packet of Matlab.The calculated pattern perfectly matched with the original one,and the standard deviation was also very small.Errors of this method were analyzed and were presented with the corresponding way to reduce them in the end.
