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

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

Treatment Method: By implementing appropriate noise insulation, noise reduction, and sound absorption measures for the noise source
