摘要:压缩机是一种高噪音工业设备，噪音包括机械性噪音和空气动力性噪音。

Abstract: Compressor is a kind of high-noise industrial equipment. The noise includes mechanical noise and aerodynamic noise. There are two main physical noise reduction measures: one is to process the sound source to suppress the sound source generated by the sound; the other is to process the sound propagation path to reduce the sound propagation. The former is to eliminate the cause of sound, and the latter is to take a path that hinders the propagation of sound. To eliminate the cause of sound, one is to prevent direct pressure changes in the air, and the other is to reduce body vibration. Controlling noise from source is the most fundamental and effective method of noise control. Through the analysis of noise, this article proposes noise reduction measures for common noise. Noise control is one of the key technical problems of compressors. Research on this problem can help reduce compressor noise, improve working environment, improve working efficiency, and increase its reliability. <br>Keywords: compressor; noise generation, pressure change reduction, vibration reduction, sound absorption treatment

Abstract: Compressor is a kind of high noise industrial equipment, noise includes mechanical noise and aerodynamic noise. There are two main kinds of physical noise reduction measures: one is to do some kind of processing to suppress the sound source produced by sound, and the other is to process the path of sound propagation to reduce sound propagation. The former is the reason for eliminating sound generation, while the latter is the path taken to prevent the propagation of sound. Eliminate the causes of sound, one is to prevent direct pressure changes in the air, the other is to reduce body vibration. Controlling noise from raw sources is the most fundamental and effective method of noise control. Based on the analysis of noise, the noise reduction measures for common noise are proposed. Noise control is one of the key technical problems of compressor, and the study of this problem can help reduce compressor noise, improve working environment, improve work efficiency and increase its reliability.<br>Keywords: compressor, noise generation, reduce pressure changes, reduce vibration, sound absorption.

Abstract: compressor is a kind of high noise industrial equipment, the noise includes mechanical noise and aerodynamic noise. There are two kinds of physical noise reduction measures: one is to deal with the sound source to suppress the sound source; the other is to process the sound propagation path to reduce the sound transmission. The former is to eliminate the cause of sound generation, the latter is to take the path of hindering sound transmission. To eliminate the causes of sound, one is to prevent direct pressure changes in the air, the other is to reduce body vibration. Noise control from students is the most fundamental and effective method of noise control. Through the analysis of noise, this paper puts forward the noise reduction measures for common noise. Noise control is one of the key technical problems of compressor.
