    摘要:

    相位麦克风阵列技术是最近十年快速发展起来的一种声学实验技术,旨在精确地识别和定位出噪声源,反演出每个声源的频率、位置和幅值信息。该技术在国外得到了快速发展和广泛应用,而在国内仍处于起步阶段。相位麦克风阵列技术的核心是数据后处理算法,本文发展了一套数据后处理算法程序,进行了相关的数值模拟研究。结果显示,该算法程序能够比较精确地识别和定位出声源信息,为今后进一步的实验研究和工程应用打下了基础。

    Abstract:

    Phased microphone array is an acoustic measurement technique developed in the past ten years, which aims to recognize and localize the noise sources precisely, reconstruct the frequency, position and amplitude of each source. It have quickly developed and widely used at abroad, but is still in initial stage at home. A set of data post-processing algorithm procedure is developed, which is the dominant element of phased microphone array technique, and some numerical simulation studies are carried out. The results show that, this algorithm procedure can recognize and localize the source information rather accurately, which is a foundation for further experiment study and engineering application in future.
