气动工具与由其它动力驱动的工具相比,具有单位重量输出功率大以及高度的耐用性与安全性等优点,因此在现代工业中具有重要的作用,并得到了迅速发展。但是气动工具工作时会产生强烈的噪声,一般都在100分贝(A)以上。噪声对人体危害很大,长时间受强烈噪声作用会使耳组织受损,降低听力,甚至造成职业性耳聋;噪声会使工人的工作效率降低,警觉性缓退,容易疏忽大意造成工伤事故;噪声对神经系统也有显著影响,会使血压升高,肌肉收缩
Pneumatic tools have the advantages of high output per unit weight and high durability and safety compared with other power-driven tools and therefore have an important role in modern industry and have been rapidly developed. However, pneumatic tools work will produce strong noise, usually at 100 dB (A) above. Noise is very harmful to the human body, prolonged exposure to strong noise will damage the ear tissue, reduce hearing, and even cause occupational deafness; noise will reduce the work efficiency of workers, alertness and retreat, easy to negligently cause work-related accidents; Noise also has a significant effect on the nervous system, causing high blood pressure and muscle contraction
