摘要
研究界面噪声场下矢量水听器声压与质点振速的相关特性。利用射线声学原理,给出了求解海洋环境场声压场与质点振速场空间相关特性的方法。通过简单的数值积分,可以方便地求解给定了海面、海底反射系数、介质声吸收系数的海洋环境下噪声场空间相关特性的问题,并给出了特定条件下的计算结果。
The spatial correlation of the sound pressure and the particle velocity in surface-generated noise was investigated.Method of calculating the correlation between the sound pressure and the particle velocity in ambient noise was developed based on ray treatment.The correlation of the sound pressure and the particle velocity in ambient noise model with given surface and bottom power reflection coefficients and volume absorption could easily be got by numerical integration.Results of given condition were shown.
