| 摘 要： | 介绍了基于麦克风阵列进行噪声源识别的基本原理,采用相位延迟对噪声源空间进行扫描,确定声源的波达方向,进而识别声源的位置。利用计算机仿真技术模拟了空间两点声源产生的噪声,并利用该算法进行了声源位置识别。理论与仿真研究表明采用相控阵列能够识别噪声源的位置,同时能够获得不同噪声源的噪声大小和噪声贡献量,利用该方法可以对列车的运行噪声源进行分析。

| Abstract: | The principle of noise sources identification is introduced on the basis of the microphone array.DOA(direction of arrive) and noise sources locations can be identified by scanning noise spaces through phase delay.It is proved through computer simulation.Noise sources can be located through the Phased-microphone array,magnitudes and contribution of noises from different sources can also be obtained.Noise sources in train operation can be analyzed by this method. |
