Essay on noise pollution

Noise pollution is the regular exposure to pre-eminent sound levels that cause hazardous effects in the living organisms. The world health organization says that any sound less than 70 decibel is not hazardous and will not cause any ill effects to the living organisms. However, sounds that are more than 70dB are considered hazardous. The excessive amount of noise out in the environment makes it unsafe to live in. The unpleasant sounds and noise can cause an imbalance in nature.

Causes of Noise Pollution:

Noise pollution is caused by various activities by the humans. The urbanization and modern civilization, and the impact of higher degree of industrialization are the sources of noise pollution. The blowout of noise is because of two different sources – industrial and non-industrial. The former one includes noise from big machines, high-speed technologies, etc., whereas, the latter is the noise from electric gadgets at home, transport, traffic etc.

Effects of Noise Pollution:

The increase in the noise leads to a decline in the quality of work done by humans. This brings a reduction in the concentration levels of humans. Temporary deafness, psychological issues, and coronary defects are the effects in humans and other living organisms. The old building and historical monuments are also affected by the noise. Plants are also affected by the increase in noise.

Conclusion:

Higher levels of noise are hazardous and it is also difficult to make them escape in a closed environment. The increased levels of noise pollution in the environment have made it an urgent need to create awareness about the causes, effects, and prevention of noise pollution. The higher level of noise should be reduced at home and also at a workplace. People should be educated about the hazards of noise pollution. Let’s all make it our responsibility to prevent the environment from further noise pollution and make the earth a better place to live in.

Answer 2

Answer:

Explanation: Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction, electrical generators, explosions, and people.

Prevention and Control of Noise Pollution

Fundamental steps should be taken to curb the increasing noise pollution

In factories the noise pollution machines should be replaced with some latest improved techniques machinery.

To minimize the noise produced by machines an insulating material should be used.

Plantation of trees should be encouraged along highways, streets and indus­trial areas because the vegetation covers absorbs the sound energy acting as a safeguard zone.

The use of ear plugs by the industrial workers can acts as a cushion from the perilous effects of noise pollu­tion.

The air traffic noise can be reduced either by suitable technique or by zoning the area around the airport and not allowing for the construction of houses or indus­tries within 10 meters of the airport.

Blowing of horns should be banned and speed limits should be prescribed for the vehicles.

Burning of crackers should be completely banned and threshold intensity should be set for  loudspeakers and music systems.
