| Abstract: | Two methods on noise source identification technology based on microphone array,STSF and Beamforming are different in theory.Differences in using ranges of these two methods can be found by proven STSF and Beamforming theory.The reasoning also shows correct frequency range and space range of these two methods.At the same time,the way that how to chose better method in use and next research direction on this topic are mentioned in this paper. |
