Abstract

The theoretical study of sound field formation in an acoustic interference array presented in this article is motivated by an analysis of the physical principle of operation of a highly directional interference microphone. One of the objectives of the study is to determine the sound pressure acting on the microphone membrane inside the array. The sound field inside the interference array is analyzed using a matrix method, similar to the reverberation matrix method. The solution is formally represented as a Schwarzschild series. The result calculated by this method agrees well with the experimental data.

利用混响矩阵法分析声学干涉阵列内部的振动过程
本文介绍的声学干扰阵列中声场形成的理论研究,是通过分析高指向性干扰传声器的物理工作原理而展开的。研究的目标之一是确定阵列内作用在传声器膜上的声压。干扰阵列内部声场的分析采用矩阵法,类似于混响矩阵法。解法形式上表示为 Schwarzschild 序列。该方法计算出的结果与实验数据十分吻合。
