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

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

Method of Treatment: By adopting appropriate noise insulation, noise reduction, and sound absorption measures towards the noise source
