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 exhaust emissions is all due to air vibration, creating airflow noise. The noise produced by ball mills, crushers, and looms, etc., 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.

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