发展了一种由１１１个传声器组成的Ｍ维平面传声器阵列测量技术，１１１个传声器在平面阵列中的位置应用随机优化的方法确定，从而保证平面传声器阵列在感兴趣的测量频率范围内具有理想的性能，并应用数值模拟的方法检验了平面传声器阵列的频谱特性．应用此平面传声器阵列对当前流行的民用客机进场着陆过程中飞机噪声源进行了测量分析，实验结果表明应用此项技术可以辨别出在飞机表面上所有重要的噪声源，并可获得全尺寸飞机机体重要噪声源的详细的频谱特性、指向特性和声级变化．
An M-dimensional planar microphone array measuring technique consisting of 111 microphones has been developed. The position of 111 microphones in a planar array is determined by a stochastic optimization method to ensure that the planar microphone array has an ideal range of measurement frequencies of interest The performance of the planar microphone array was verified by numerical simulation. The planar microphone array is used to measure and analyze the aircraft noise sources during the landing of the currently popular commercial passenger aircraft. The experimental results show that using this technology, all the important noise sources on the surface of the aircraft can be distinguished and the full-size aircraft can be obtained The detailed spectrum characteristics, directional characteristics and sound level changes of the important noise sources of the body.
