Industrial noise refers to the sounds produced during the manufacturing process due to mechanical vibrations, frictional impacts, and air flow disturbances. For example, the noise generated by air compressors, blowers, and boiler exhausts in factories is aerodynamic noise resulting from air vibrations. The noise produced by ball mills, crushers, and looms, among others, is mechanical noise caused by the vibration or frictional impacts of solid components.

General noise is categorized into: mechanical noise, aerodynamic noise, and electromagnetic noise.

Processing Method: By adopting appropriate noise insulation, noise reduction, and sound absorption measures for the noise source
