摘要
从理想活塞声源声场的计算方法入手,引入脉冲波修正和衰减修正,推导出了适用于连续波和脉冲波声场计算的公式,并论述了超声波声场的的数值计算方法.同时编制了声场计算程序,实现了超声波声场的计算机仿真.
The calculating formula for sound field of continuous ultrasonic and impulse ultrasonic is derived in this paper, and numerical calculating method for ultrasonic field is discussed. A computer program is written with java language, which calculates and simulates an ultrasonic field with color cloud diagram and curve.
