Answer:
Noise pollution or sound pollution refers to the dangerous and unwanted level of disturbance caused by noise. Noise is measured in decibels or dB. A sound more than 85db is said to be a damaging level of sound that, over time, can causing hearing loss. Noise pollution is a problem faced all over the world.
There are numerous sources of noise pollution. One of the primary causes is industrialization, especially in urban areas. Industries use heavy equipment such as generators, compressors, mills, etc. that make high pitched sounds that are very unpleasant and cause a disturbance. Road traffic is another major contributor to noise pollution. Increased transport of cars, motorcycles, trucks, etc. have to lead to increased noise disturbance on the road.
Construction of roads, buildings, apartments, highways, etc. uses heavy equipment such as excavators, compressors, hammers, etc. These create a lot of noise, causing disturbance to its surroundings. Poor urban planning such as congested living spaces, large families living in a small area, parking spaces, etc. causes many fights as they are competing for the same resources. The use of firecrackers during festivals is also a source of noise pollution. These crackers generate very high pitched and sudden sounds. They are contributing to noise as well as air pollution. Another source of noise pollution includes playing loud music, especially during social events like marriages. Low flying aircraft of the military also cause noise pollution. Ocean sound pollution is caused due to submarines. Other sources of noise pollution include household equipment, air conditioners, kitchen appliances, etc.
Noise pollution primarily affects a person’s hearing, leading to hearing impairment to even permanent loss of hearing. It causes an increase in blood pressure, hypertension, fatigue, and cardiovascular diseases. Noise pollution also disturbs a person’s state of mind causing disturbed sleep patterns, stress, aggressive behavior, decreased concentration, and poor quality of life. Noise disturbance is extremely dangerous to elderly people and pregnant women.
Noise pollution also affects wildlife and marine life. Animals have a more advanced hearing. Noise pollution can impact their listening skills and cause changes in their behavior, starting with a pet at home. It leads to changes in their hearing due to which their communication also becomes affected. They are unable to hear properly during migration as they require sound to find their way. Noise pollution also affects crop production. Ocean sound pollution causes internal damage such as cardiovascular problems and physical problems such as hearing impairment in marine life. They are forced to leave viable habitats.
There are noise pollution preventive measures available. Soundproof walls and windows are one way to prevent noise pollution from entering the premise. Faulty equipment must be checked and repaired regularly. Needless honking must be discouraged. Many hospitals and schools are silent zones to ensure that disturbance does not occur. Rules to prevent noise at certain hours are in place, which many governments have implemented. Using earplugs and switching off appliances when not required, can also help. Planting trees can also help as they absorb noises. International Noise Awareness Day is witnessed every year, usually on the last Wednesday of April. This day was marked on April 29 in 2020.
