本文分析了空气锤噪声的基本组成及其基本特性，指出空气锤在工作时不但存在排气噪声也存在进气噪声，并且进排气噪声对操作工人及其周围环境的危害最为严重。深入分析了空气锤４种不同工作循环中的进排气特性，应用声学理论，分析了进排气噪声产生的机理及其特性。指出了空气锤４种不同工作循环进排气噪声特性的差异。明确指出空气锤轻打时产生的排气噪声值最大，并对理论分析的结果进行了实验验证
This paper analyzes the basic composition of hammer air noise and its basic characteristics. It is pointed out that air hammer not only has exhaust noise but also intake noise during operation, and intake and exhaust noise is the most harmful to workers and their surroundings. In-depth analysis of the air hammer inlet and exhaust characteristics of four different working cycles, the application of acoustic theory, analysis of the intake and exhaust noise generation mechanism and its characteristics. The difference of the noise characteristics of air intake and exhaust of four different working cycles of air hammer is pointed out. Clearly pointed out that when the air hammer light hit the maximum value of exhaust noise, and the theoretical analysis of the results of an experimental verification
