基于由单双泡动力学方程和Lighthill 方程创建起来的单双泡空化噪声模型，通过Matlab 语言编程计算，分析了水中空化泡的初始半径、双泡间距、声压幅值、超声频率、双频超声等因素对空化噪声的影响．计算及分析结果表明: 在相同的初始条件下，单双泡的空化噪声曲线有不同的形态，双泡产生的空化噪声远大于单泡; 对于单泡，空化泡的初始半径、声压幅值、超声频率、双频超声对空化噪声均有影响，其中空化泡初始半径和声压幅值的影响最为显著，在双频条件下，两声压分量幅值相等时单泡空化噪声达到最大．对于双泡，初始半径和声压幅值对空化噪声影响很大，而超声频率和双频超声对空化噪声的影响几乎可以忽略．

Based on the single-bubble and double-bubble ultrasonic cavitation noise models derived respectivelyfrom the single-bubble and double-bubble dynamic equation and from the Lighthill equation,the effects of the initialbubble radius,the double-bubble distance,the sound pressure amplitude,the sound frequency and the bifrequencyultrasound on the cavitation noise are analyzed via Matlab programming.Calculated and analytical resultsshow that ( 1) under the same initial conditions,the peak of the double-bubble cavitation noise is much higher thanthat of the single-bubble one,which means that the single-bubble and double-bubble cavitation noise curves are differentform each other; ( 2) the initial radius,the sound pressure amplitude,the sound frequency and the bifrequencyultrasound all affect the single-bubble cavitation noise,especially the former two; ( 3) the cavitation noisereaches the maximum when the pressure amplitudes in the two components of the bifrequency ultrasound are equal;and ( 4) the initial radius and the sound pressure amplitude influence the double-bubble cavitation noise significantlywhile the effects of the sound frequency and the bifrequency ultrasound are almost ignorable.
