Sound Intensity Test Analysis of the Acoustic Enclosure for the Refrigeration Compressor

Abstract:

According to the international standard ISO 9614-1:1993 " Determination of sound power levels of noise sources by the sound intensity method - Part1: Measurement at discrete points, the sound intensity test was conducted on the acoustic enclosure for the refrigeration compressor with the PULSE software. The sound insulation performance of the acoustic enclosure was analyzed by comparing the compressors noise with and without the enclosure. The result shows that the noise of the compressor with the acoustic enclosure is less than 60dB (A), and the high-frequency noise can be greatly reduced, which meets the design requirements of noise control. Therefore, it is easy to conclude that the sound insulation of the acoustic enclosure reaches the design standards and the acoustic enclosure design is feasible. The paper provides a valuable reference for the further study on the designing and optimizing of the acoustic enclosure.
