【Abstract】 The noise source and its characteristics of air compressor are analysed.The comprehensive noise control by use of the techniques of vibration isolation,sound insulation and noise reduction are taken for an unit of air compressor Z-0.36/7,its noise has already been reduced down from 89 dB (A),the actually measured maximum level,to 70 dB(A).The results of noise reduction and puri- fying the environment are obvious and satisfactory.The practical approach describing in this paper is more simple and effective,and the performance of operation is stable.更多还原
