| Abstract: | The Spatial Transformation of Sound Field(STSF) is applied to noise source separation and identification in this paper. The numerical simulation for the NAH(Near Field Acoustic Holography) and BAHIM (Broadband Acoustic Holography based on Intensity Measurement) has been taken. The result show that when the proper location and discernment of noise sources can't be given by pressure or intensity distribution at the measurement surface, the STSF can solve the problem well. The experiment of the NAH and BAHIM for underwater noise source demonstrate that the STSF is particularly suitable for the study of noise source. |
