In this work, the mechanism of structure-borne noise resulting from vibration of a compressor for a refrigerator is experimentally analyzed and an effective method is proposed to reduce the noise. Firstly, the emission noise, when the compressor is turned on and off, is measured and analyzed to identify the generation mechanism of structure-borne noise. And the acceleration on the outer wall of the refrigerator is also analyzed to identify the distribution of vibration. Secondly, an effective design method to reduce the noise is suggested by using the finite element analysis and Taguchi method. Consequently an optimal design of the refrigerator, which has lower noise, is obtained and then its performance and validity are verified through the analysis and test.
