It is well known that the major noise source of a refrigerator is the compressor, and due to the tendency of higher quality and more lighter weighty of manufactured goods, the importance of prevention and reduction of noise is increasing. In this paper, in order to prevent and reduce such noise, sound pressure level and acoustic intensity are measured for the compressor, and the results of these measurements, the noise radiation characteristics of the compressor are identified. Also the experimental modal analysis is applied to the compressor to identify the noise source.
