article on noise pollution of class 9
Noise pollution is the pollution caused by the various noise sources whether by the industrial or non-industrial affecting the human beings, plants and animals health in many aspects. Regularly increasing level of the noise pollution is keeping the lives of people of present generation and coming generations at high risk. I have discussed below the sources, effects, legal aspects control noise pollution and conclusion of the noise pollution.
Following are the sources of noise pollution
The level of noise pollution has been increased a lot in India by the urbanization, modern civilization, industrialization, etc. The spread of noise is caused by the industrial and non-industrial sources. Industrial sources of noise include the use of big machines of high technologies working at high speed and high level of noise intensity in the various industries. Non-industrial sources of noise include noise created outside the industries such as through the transport, vehicles traffic and other means by people. Non-industrial source of noise can be natural or man made. Some of the industrial and non-industrial sources of noise pollution are mentioned below:
Noise created by the low flying military aircraft has also added noise pollution to the environment to a great extent.Road traffic noise is increasing day by day in the city because of the motors and exhaust system of vehicles like trucks, buses, autos, motorcycles, personal cars, etc. Tall buildings in the cities cause noise to resound in that area for some time.Industrial noise created by the manufacturing plants because of the use of motors, compressors, fans, etc.Construction noises created by the construction of tall buildings, roads, highways, city streets, etc through the use of pneumatic hammers, bulldozers, air compressors, dump trucks, loaders, pavement breakers, etc.Rail roads noise (from locomotive engines, whistles, horns, switching or shunting operations in the rail yards) are also very effective in the creating high level of noise pollution as they create peak level of noise of around 120 dB to the 100 feet distance.Noise created in the building because of the plumbing, generators, boilers, household equipments, music, air conditioners, vacuum cleaners, kitchen appliances, fans, and other noisy activities in the neighborhood.Another source of noise pollution is the use of variety of fire crackers (high sound generating) during the festivals and other family occasions.
Following are the effects of noise pollution
Noise pollution highly affects the health of human beings, animals and properties. Some of are mentioned below:
Increasing noise pollution day by day is decreasing the efficiency and quality of work of human beings.Noise pollution reduces concentration level as high level of noise causes fatigue and tiredness.Hugely affects the pregnant women and cause irritation and abortion.Causes various diseases (high blood pressure and mental illness) to the people because it disturbs the peace of mind.High level of noise decreases quality of work and thus causes lack of concentration level.It may cause temporary or permanent deafness because noise level of 80 to 100 db is unsafe for the people.It also damage historical monuments, old buildings, bridges, etc because it weakens the structure by creating dangerous waves which struck to the walls.Animals lose control on their mind and can be more dangerous because high level noise damage their nervous system.It also affects the plants and causes poor quality crops production.
Following are legal aspects to control noise pollution
Constitution of India guarantees right to life, right to information, right to religion and noise.Section 133 empowers human being to remove a public nuisance on a conditional or permanent order.Noise Pollution Control Rule 2000 under Environment Protection Act 1996 involves controlling the growing problem of noise pollution.Factories Act Reduction of Noise and Oil of Machinery limits for noise exposure in the work zone.Motor Vehicle Act involves the use of horn and change of fault engines.Indian Penal code deals with the health and safety issues caused by the noise pollution. One can be penalized under law of torts.
Increasing level of noise pollution has created the urgent need of general awareness about the sources, effects and preventive measures of the noise pollution. High level of noise should be prohibited in the areas like working places, educational institutes, residential areas, hospitals, etc. Young children and students should be motivated to not get involved in the high sound producing acts like use of high sound generating equipments and instruments on the occasions. Use of high level sound generating fire crackers should be reduced during the occasions like festivals, parties, marriages, etc. Subjects related to the noise pollution should be added into textbooks and activities can be organized in the schools like lectures, discussion, etc so that new generations can be more aware and responsible citizens
Noise pollution can be defined as unwanted or offensive sounds that unreasonably affect our daily activities. The term noise is very subjective. Sometimes when you are concentrating on your work then even a mild conversation or whisper sound may become a noise. On the other hand if you are in light mood in a party, then even many people talking does not seem to be noise. Major Sources of Noise Pollution:
i. Road traffic:
Road traffic noise is one of the most widespread and growing environmental problems.
ii. Air and rail traffic:
In areas close to the airports and railway tracks, the sound of aeroplanes and trains are major sources of noise pollution.
iii. Neighbourhood and domestic noise:
Barking dogs, car horns, loud music, TVs, loudspeakers, construction and household noise are some of the major sources of noise pollution.
iv. Noise from industries:
At many places, industries are located in close proximity of the residential areas or within the residential areas. Sound of machines, etc. causes noise pollution.Harmful Effects of Noise Pollution:
i. Noise can affect human health and well-being in a number of ways, including annoyance reaction, sleep disturbance, interference with communication, performance effects, effects on social behaviour and hearing loss.
ii. Noise can cause annoyance and frustration as a result of interference, interruption and distraction.
iii. People experiencing high noise levels have increased number of headaches, greater susceptibility to minor accidents, increased reliance on sedatives and sleeping pills, increased mental sickness.
iv. Exposure to noise is also associated with a range of possible physical effects including cold, changes in blood pressure, other cardiovascular changes, problems with the digestive system and general fatigue.
v. Prolonged exposure to noise levels at or above 80 dB can cause deafness because of damage to the organ of Corti in the internal ear.How to Control Noise Pollution?
The unit of sound measurement is decibel (dB). Decibel is the unit for measuring the relative loudness of sounds equal approximately to the smallest degree of difference of the loudness that human ears can normally detect. Some levels of sound and their sources.
The noise pollution can be minimized in following ways:
i. Reduce the noise at its source in industries and automobiles, etc.
ii. Try not to put the TV on hi-fi speakers.
iii. When playing music, turn it down at a reasonable level. Better still use headphones if you want to play your music loud or late at night.
iv. Plant trees at roadsides, curtains on the doors and windows, glass panes at the windows etc. to interrupt the path of the noise. This will reduce the noise to some extent.
v. Do not unnecessarily blow horns. This disturbs others.
vi. If the source of noise is unavoidable cover your ears by hands or use ear plugs to avoid noise.
