摘要
基于传声器阵列的产品噪声源定位技术有两个主要方法:STSF和Beamforming,但两者的实现方法各不相同。通过对STSF和Beamforming声源定位技术的推导,给出了两种测量技术适用的频率范围和空间范围,从理论上对其应用范围的差异进行了说明,并提出了在实际测量中如何选择合适的声源定位方法。结合两种测量技术的特点,还提出了声源定位技术下一阶段的研究课题。
The two methods of noise source identification technology based on microphone array- STSF and Beamforming-are different in implementation. The differences in using ranges of these two methods are explained by the derivation of STSF and Beamforming technology, and the correct frequency range and space range of these two methods are given. The way to choose the better method in practical measurement is proposed. The future research direction on this topic are presented in this paper.
