Noise pollution is define as exposure to elevated sound levels that may lead to severe affects in humans or other living organisms. Sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Being in contact with these elevated noise beyond 85 dB for more than 8 hours may be hazardous. Noise pollution could be caused by Industrialization: Most of the industries use big machines which are capable of producing large amount of noise. Stuff like drills, vacuums and motors also are involved in producing big noise. Workers in these factories and industries wearing ear plugs to minimize the effect of noise. Events: Noise is at its highest point in most of the events. Whether it is, parties, concerts or place of worship. People play songs on full volume and dance which makes the condition of people living nearby pretty bad. In markets, you can see people selling clothes using loud noise to attract the attention of people. Poor Planning: In most of the developing countries, poor planning also play a vital role. Large families sharing small space, over crowded places etc. leads to noise pollution which may disrupt the environment of society and there are many more to talk about.
Plant & Trees
Human noise can have a continuing effect on long-lived plants and trees that can last for decades even after the sources of noise. Many plants and trees rely on birds and other animals but many animals are adapting to the noise by changing their behavior or moving to quieter areas. As a result, noise pollution is altering the landscape of plants and trees.
By changing balance between predator and prey detection and avoiding and interfering with the use of sounds in communication, especially in reproducing and navigation, noise can have a damaging effect on animals, increasing their risk of death. In loud places, some birds have to sing at higher frequencies, bats and owls can have trouble finding prey, small mammals lose habitat by avoiding areas with roads and construction, frogs can struggle to find mates, a population’s evolution path can be altered by loving to other activities and thus lead to great genetic and evolutionary consequences, various species experiencing hearing which in the case of endangered species may be part of the path to extinction
Human made noise is disrupting life below the surface where almost every living creature depends on sound as a primary sense for mating, communicating, hunting, and survival. The rising level of underwater sound produced by industrial ocean noise, oil and gas exploration, shipping traffic, military sonar and other human made sources can cause distress in marine life with a deadly condition known as ‘the Bends’ and is a significant long-term threat to whales, dolphins, fish and other marine species.
The concern for environmental protection had its beginning in the 1960 s, when many laws regarding this were passed by several states of the USA. The “National Environmental Policy Act” and was signed by the President of the USA on January 1, 1970. Some states of the USA now provide that citizens may bring environmental violations to the attention of government authorities and receive a reward. In Japan, the “Anti-Pollution Basic Law” covers noise pollution. A National Council has been established in Japan the Prime Minister. This Council controls the quality of air, water, noise, earth vibrations caused by construction work and land transport vehicles.
In the United Kingdom, laws for pollution control are as old as their history. Even in the thirteenth century, controls were imposed on the activities which presented an immediate threat to health. The “Noise Abatement Act (I960)” of the UK makes provision in respect of the control of noise and vibration with a view to their abatement. Anti-pollution laws have been passed in many other countries. For a comprehensive examination of the legal aspects of noise pollution,
Noise pollution isn’t good. It interferes with our ability to hear sounds of higher “quality,” though quality is in the ear. Noise can wreck your sleep, a noisy environment disturbs sleep in various ways, indoor noises above 50 db affect sleep more than outdoor noises of the same level. Noise exposure during sleep has been found to trigger an increase in heart rateand body movements. Disturbed sleep could also have after-effects on mood and performance during the following day. Scientific Studies have shown that one’s ability to perform difficult mental tasks involving memory and choice of strategies for carrying out tasks becomes impaired after noise exposure. Noise has also been found to increase aggression and decrease helping behavior
