The unit of noise is decibel. Human ear can tolerate noise up to 120 decibels. There are various sources that causes noise pollution. Industrial causes. The high intensity of sound created by machines in varied industries, mills, and factories square measure the foremost causes of commercial pollution.
A person's overall noise exposure may come directly from an individual machine, but noise from other machinery or processes elsewhere in the workshop may also contribute to this. This means that as well as a machine operator people at risk include those working nearby, for example, maintenance fitters, cleaners, fork lift truck drivers and shop floor supervisors.
The presence of excessive or unwanted sounds in the environment is called noise pollution. Major causes of noise pollution are sounds of vehicles, explosions including bursting of crackers, machines, loudspeakers, television, and transistor radio at high volumes, some kitchen appliances, etc.
