| Abstract: | The acoustical properties of the suction and discharge chamber are calculated and analyzed, some ways to reduce the compressor noise through changing the structure of the suction or discharge chamber are presented. Based upon improving structural design of the suction or discharge cavity of the compressor, the comparison measurements of compressor noise are made. Sound attenuations to some extent are obtained . |
