4. Industrial noise is caused by some high intensity decibels that is the result of industry machines and other such appliances. The noise comes from the use of mills, heavy industrial machines and even the small exhaust fans that run for a long period. Noise from mechanical saws and pneumatic drills is unbearable and the ultimate form of pollution to the public and neighborhood. This is one cause of noise pollution. Industrial  areas, the permissible limit is 75  dB  for daytime and 70  dB  at night. Industrial Noise

5. Transport noise is simply inevitable. The traffic jams cause considerable amount of vehicle noise and the honking of the many vehicles in the crowd are nothing but a pure nuisance. Whether road, rail or aircraft, their noise is a considerable contributor to noise pollution. Tractors and other heavy vehicle sounds are difficult to control for their sound. Transport Noise

6. Gadgets, electrical appliances like the grinder and mixer are the prime contributors to noise pollution. Loud loudspeakers in the name of wedding, political parties and other such events call for a significant amount of noise pollution. In the long run, they become difficult to bear posing problems to the health of humans. And no! Humans are the not the only ones to get affected. Marine animals also suffer a disturbance in their cycle. Some of these types of noise pollution cannot be really controlled for and calls for other ways for us to take care of ourselves.
