Noise pollution is the unwanted sound dumped into environment without regard to the adverse effect it may have. Noise pollution may be defined as any unwanted electromagnetic signal (sound) that produces a jarring or displeasing effect and which interferes with human communication, comfort and health. Noise pollution also caused when the loudness of the sound becomes irritating or unbearable.

The different machines of numerous industries, factories and mills produce a lot of high intensity sounds causing noise pollution. Some industrial processes like weaning, ship building, boiler making, pressing and blasting operations are nosier than others. The operations in pneumatic drills, milling machines, cutters, printing press with an upward, downward and sideways movement and vibrations, cause lowering of hearing capacity to a large extent.

The noise pollution is further magnified due to the installation of industries in compact places. For example, the workers near the heavy industrial blowers in steel industry are exposed to sound of 120 dB for eight hours and hence suffer from occupational pollution.
