Summary

Based on the theory and characteristics of the near-field acoustical holography (NAH), the scroll compressor acoustic holography measurement is achieved in this paper. The sound field color image is reconstructed by using the measurement data, and then the noise positions of various frequency bands are identified and located. Moreover, the effect of mechanical structure on the noise is analyzed. Then, by optimization and designing of the relevant structural, the noise of the scroll compressor has been effectively reduced. This technology applied successfully to the noise test of the scroll compressor, not only to make up the problem of insufficient information of the traditional measurement method, but also greatly improve work efficiency and shorten the product development cycle.
