Provisions on dust and noise in occupational disease prevention:

One, Noise: The sources of noise are various. The noise generated in industrial production can be roughly divided into three categories: (1) Aerodynamic noise: such as air blowers, air compressors, steam turbines, pneumatic tools, Noise generated by whistle, etc. (2) Mechanical noise: noise generated by punching machines, ball mills, lathes, chainsaws, rollers, shears, looms, etc. (3) Electromagnetic noise: noise generated when electrical equipment such as generators, transformers, and power relays are operated. The harm of noise to the human body is multi-faceted. In general, it can be summarized as follows: (1) Noise can damage human auditory organs; the degree of noise damage hearing is related to the time and intensity of human contact noise. (2) Noise can cause a variety of diseases: such as the nervous system, cardiovascular system, digestive system and affecting people's normal life. The degree of influence is related to the strength of noise and the length of contact time. Controlling and preventing the hazard of noise should begin with the elimination or control of noise sources and the reduction of noise intensity in the path of noise propagation. For noise that cannot be eliminated or controlled from the source and propagation path, individual protection at the noise receiving point is required. Commonly used personal protection measures are: let the workers put anti-sound cotton or wear anti-noise earplugs, helmets and other anti-noise protective gear in the ear hole, and protect the noise from the human ear.
