Noise Pollution Essay 1 (100 words)

Noise pollution is considered as the environmental pollution caused in the environment by the excess level of noise through many sources. Noise pollution is also known as the noise disturbance. Excessive noise is harmful to the health and cause imbalance to the human or animal life. It has been a massive environmental issue in India which needs a proper attention to be solved however it is less dangerous than the water, air and soil pollution. Outdoor noise is hugely caused by the sources like machines, transportation systems, poor urban planning (construction of side-by-side industrial and residential buildings), etc. Indoor noise sources are household machines, building activities, loud music, etc. The most common impairment caused by the noise pollution is the permanent hearing loss due to ear drum damage.

Noise Pollution Essay 2 (150 words)

Normal level of the sound is necessary to maintain the daily lives however undesired sound or noise which is not tolerated by the people, animals or plants causes noise pollution in the environment. Noise is commonly called as the unwanted sound created by many industrial or non-industrial sources used in the daily life in our surrounding. High level sound creates unpleasant effects and discomfort to the health especially to the ears.

Unwanted sound generally interferes with the daily routine activities like sleep in night, conversation, hearing ability, feeling of well being, etc. Water animals are also affected by the noise pollution created by the noise of submarines and big ships in the ocean. Forest animals have been affected to a great extent due to the chain-saw operations (create extreme noise) by timber companies. Common sources of the noise pollution are household gadgets, transport vehicles, jet planes, helicopters, industrial machines, etc. According to the World Health Organization, industries must limit their sound production by 75 dB.

Noise Pollution Essay 3 (200 words)

Noise pollution is the pollution caused by the high and unsafe level of noise in the environment causes lots of health disorders to the human beings, animals and plants. Common problems caused by the noise pollution are stress related illnesses, anxiety, communication problems, speech interference, hearing loss, lost productivity, sleep disruption, fatigue, headache, irritability, nervousness, weakness, reduce sensitivity to sound which our ear receive to maintain body rhythm, etc. It causes gradual impairment to the hearing ability over a long period of time. Continuous exposure to high level sound causes permanent damage to the eardrum.

High level of the noise causes huge nuisance, injuries, physical trauma, bleeding around brain, large bubbles in organs and even death to the marine animals specially whales and dolphins as they use their hearing ability to communicate, find food, defend and survive in water. Source of noise in the water is navy submarine’s sonar which can be felt around 300 miles away. The consequences of the noise pollution are more dangerous and worrying in the near future.

There are many preventive measures of the noise pollution, some are like promoting soundproof rooms construction in the industries, industries and factories should be away from the residential building, repairing of motorbikes having damaged exhaust pipes, ban of noisy vehicles, airports, bus, railway stations and other transport terminals should be far from the living places, declaring silence zones near educational institutes and hospitals, allowing more vegetation along with roads and residential areas in order to reduce noise pollution by absorbing sound.

Noise Pollution Essay 4 (250 words)

Noise pollution is caused by the high level of unwanted sound in the environment which causes pain. Some of the main sources of the noise pollution are like noise generated by the road traffic, air craft noise, railroads noise, noise generated by the construction (of buildings, highways, city streets, flyovers, etc), industrial noise, noise created in home on daily basis (due to electrical home appliances, plumbing, generators, air conditioners, boilers, fans, etc), and noise from consumer products (like household equipments, kitchen appliances, vacuum cleaners, washing machine, mixer, juicer, pressure cooker, TV, mobile, dryer, cooler, etc).

In some countries (highly populated countries like India, etc) poor urban planning also plays vital role in the noise pollution as this planning includes the construction of congested houses having large families in small space (causing fight for parking, fights for basic requirements, etc) lead to the noise pollution. New generation people play music in full volume and dance for late night causing lots of physical and mental disturbances to the neighbors. High level of noise causes loss of normal person’s ability to hear properly. High level of noise slowly affects the health and acts as slow poison.

It hugely affects the wildlife, lives of plants, and human beings. Normally, the ability of our ear is to accept the only certain range of sounds without making any damage to the ear. However, our ear cannot bear the regular exposure to loud levels of noise and get damage to the ear drums which results in the temporary or permanent loss of hearing. It also causes other disorders like sleeping disorders, fatigue, weakness, cardiovascular issues, stress, high blood pressure, communication problem, etc.

There are various types of pollution in the environment, soil pollution is one of them and have become more dangerous to the health. It has become so dangerous that it can be compared to the other most dangerous problems like cancer, etc in which slow death is sure. Noise pollution is the dangerous gift of modern living style and increasing level of industrialization and urbanization. If regular and effective actions are not taken to control, it can be very serious to the future generations. Noise pollution is the pollution caused by the noise due to the increased level of unwanted sound in the environment. It is a big potential hazard to the health and causes huge level of communication problems.

High level of noise brings irritation in the behavior of many people especially diseased, old people and pregnant women. Unwanted sound causes deafness problem and other chronic disorders to the ear like damage to the ear drum, ear pain, etc. Sometimes high sound music pleases the listeners however irritates other people. Any undesired sound in the environment is injurious to the health. Some of the sources participating highly in the noise pollution are industries, factories, transportation, traffic, aeroplane engines, train sounds, home appliances, construction, etc.

The noise level of 60 db is considered as the normal noise however, noise level of 80 db or above become physically painful and harmful to the health. Cities having high noise quantum are Delhi (80 db), Kolkata (87 db), Bombay (85 db), Chennai (89 db), etc. Limiting the amount of noise to a safe level has become very necessary for the life on the earth as undesired noise affects the health of human beings, plants and animals too. It is possible through the general awareness among public about the noise pollution, its main sources, it’s dangerous effects, as well as all the possible preventive measures to get prevented from the noise pollution.

Noise Pollution

Noise pollution is caused by the noise when the level of noise gets increased than the normal level in the environment. Excessive amount of noise in the environment is unsafe for the living purpose. Unpleasant sound causes various disturbances in the natural balance. High volume noises are unnatural and create difficulty in escaping those generated noises. In such a modern and technological world, where everything is possible through the electrical appliances at home or outside the home, the risk of noise has been increased to a great extent.

Increasing the demand of urbanization and industrialization in India is causing major exposure of people to the unwanted sounds. Understanding, planning and implementing strategies to get prevented from the noise pollution has been necessary to curb within time. The sounds we make in our everyday life like loud music, unnecessary use of television, phone, traffic, dog barking and etc noise creating sources have become part of the urban culture as well as most disturbing things causing headache, sleep disturbances, stress, etc. Those things causing disturbance to the natural rhythm of life are called as dangerous pollutant. Following are the causes or sources and effects of the noise pollution:

Causes of Noise Pollution

  • Industrialization is putting our health and life at risk because all the (big or small) industries are using big machines producing high pitch sound in large amount. Other equipments (compressors, generators, exhaust fans, grinding mills) used in the factories and industries also produces big noise.
  • Regular social events like marriages, parties, pub, club, disc or place of worship, temples, etc create nuisance in the residential area.
  • Increasing transportation in the cities (vehicles, aeroplanes, underground trains, etc) produces heavy noise.
  • Regular construction activities (including mining, bridges, building, dams, stations, roads, flyovers, etc) involve big equipments creating high level of noise.
  • Use of household appliances in our daily life is also the main reason noise pollution.

Effects of Noise Pollution

  • Noise pollution causes various hearing problems (damage to ear drums and loss of hearing) because of the unwanted sound.
  • It reduces ear sensitivity to the sounds required to regulate body rhythm.
  • It affects the psychological health and causes the occurrence of aggressive behavior, sleep disturbance, stress, weakness, fatigue, hypertension, cardio-vascular diseases including other severe and chronic health issues in later life.
  • It creates communication problems and lead to misunderstanding.
  • Affects wildlife and makes pets more aggressive.

Preventive Measures:

General awareness should be increased among people and all the rules should be followed seriously by everyone in order to control the unsafe sound level in the environment. Unnecessary use of things generating high pitch sound should be reduced in the home or outside the home like clubs, parties, bars, discos, etc.

Noise Pollution

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.

Conclusion

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.

Essay on Noise Pollution: Sources, Effects, Prevention and Control of Noise Pollution!

The word ‘Noise’ is derived from the Latin word ‘nausea’ which means feeling of sickness at the stomach with an urge to vomit. The term noise may be defined in a number of ways.

For example:

(i) In acoustic, noise is defined as unwanted, unpleasant and annoying sound.

(ii) Noise is defined as unwanted, unpleasant, disagreeable sound that causes discomfort.

(iii) Noise is defined as the wrong sound, in the wrong place at the wrong time.

(iv) Noise is the sound incidental to our civilization and is without agreeable musical quality.

It is seen that a particular sound which is musical to some­one, may be noise to another. However, if the sound is loud and it prolongs for a longer period of time, it becomes noise for all. (The technological advancements such steam engines, diesel en­gines, jet engines, industrial machinery, traffic noise of moving trucks, buses, cars, and automobiles with blow horns, etc. are polluting the atmosphere with their continuous noise.

So, now a day’s noise is considered as a component of environmental pol­lution having a potential to cause hazards to human health and communication.) It may be noted that sound is a pure tone, harmonically related, occurring at regular intervals and producing meaning full communication whereas noise is a complex mixture of a number of pure tones of varying frequencies and amplitudes.

Noise pollution may be defined in a number of ways:

(i) According to Odum, noise pollution is the unwanted sound dumped into environment without regard to the adverse effect it may have.

(ii) Noise pollution may be defined as any unwanted elec­tromagnetic signal (sound) that produces a jarring or dis­pleasing effect and which interferes with human com­munication, comfort and health.

(iii) According to Ambast (1988), noise pollution is caused when the loudness of the sound becomes irritating or unbearable.

(iv) Noise pollution also refers to perturbations which inter­fere in the communication systems.

The unit of sound intensity is decibel (dB). The sound inten­sity from 0 to 100 dB is pleasant but when the sound intensity exceeds 120 dB, it causes noise. Sound intensity of 130 dB is the upper limit of the threshold of hearing and beyond this, is the threshold of pain which may cause damage to car and leading to hearing impairment. So, sound of more than 130 dB causes noise pollution.

1. Sources of Noise Pollution:

Noise may originate either from natural sources or from anthropogenic activities. The natural sources of noise include thunder, cyclone, roaring of sea, etc. The manmade noise are mechanized automobiles, industries, trains, aero planes, social functions etc. It may be noted that the manmade noise is now doubling after every decade.

Broadly speaking, the noise may be classified into:

(1) Transport noise;

(2) Industrial noise; and

(3) Neighborhood noise.

1. Transport noise:

The main threat of noise comes from transport sector. The transport noise includes road traffic noise, rail traffic noise and aircraft noise.

(a) Road traffic noise:

The chief causes of road traffic noise are the number of road vehicles and their high traffic speed. Faster moving vehicles produce high noise from their gear box, exhaust system, vibrations from their body, etc.

(b) Rail traffic noise:

The noise from rail traffic is compara­tively lower than that from road traffic. Introduction of diesel engines or electrical engines has reduced the in­tensity of rail traffic noise which was previously shown by steam engine. Besides use of welded tracks and im­proved coach suspension have contributed to the reduc­tion in railways noise,

(c) Aircraft noise:

Larger and faster aircrafts produce high noise intermittently during takeoff, landing and during flight. Noise generates from compressor and turbine and near jet exhaust. Jet engines create most noise around a radius of 16 km. Sonic boom is an important aspect of aircraft noise. Sonic boom occurs when an aircraft flies supersonically overhead.

(2) Industrial noise:

The different machines of numerous industries, factories and mills produce a lot of high intensity sounds causing noise pollution. Some industrial processes like weaning, ship building, boiler making, pressing and blasting op­erations are more nosier than others.

The operations in pneu­matic drills, milling machines, cutters, printing press with an up­ward, downward and sideways movement and vibrations, cause lowering of hearing capacity to a large extent.

The noise pollution is further magnified due to the installation of industries in com­pact places. For example, the workers near the heavy industrial blowers in steel industry are exposed to sound of 112dB for eight hours and hence suffer from occupational pollution. Some typi­cal industrial noise levels are given in table 10.1.

Table 10.1: Some Typical Industrial Noise Levels

Industrial Source

1. Steel plant riveting

130

2. Oxygen torch

8. Bench lathe

95

9. Milling machine

90

10. High speed drill

85

11. Key Press machine

82

12. Super market

3. Neighborhood noise:

This type of noise includes antisocial activities of neighbors like using of loud TV, stereo, radio sets, jazz music, fireworks parties, playing of children, bark­ing of dogs, neighborhood brawls out of intoxication and indus­trial neighborhood noise etc. The machines used in house con­struction like concrete mixes, vibrators, bulldozers, heavy diesel lorry, building demolition activities also add to the noise pollu­tion.

The central pollution board (India) has prescribed permissible sound levels for cities, divided into four zones as given in table 10.2.

Table 10.2: Permissible Sound Levels As Prescribed By Cen­tral Pollution Control Board.

 

Areas

3.

Residential area

50 dB

45 dB

4.

Sensitive areas upto 100 meter around hospitals educational institutions, courts etc.

50 dB

40 dB

2. Effects of Noise Pollution:

Noise is air-borne mechanical energy striking the human eardrum. A sound of 65dB is the noise level for con­versation heart at a distance of one meter. A sound of 125dB (A) gives the sensation of pain in the ear and 150dB (A) might kill a human being. If a noise of 90dB in the mid-frequency range reaches the ear for more than few minutes, then the sensitivity of the ear is reduced.

The various effects of noise pollution on human beings may be classified in to two categories:

(1) Auditory effects; and

(2) Non-auditory effects.

1. Auditory effects:

The impairing of hearing which may cause immediate auditory fatigue finally leading to deafness is known as auditory effects.

2. Non-auditory effects:

These effects include interference with speech communication, annoyance leading to ill-temper, bick­ering, mental disorientation, violent behavior and a series of health hazards.

In addition to serious loss of hearing, noise also causes patho­logical (or psychological), non-pathological (or physiological) and vibrational disorders.

(a) Pathological disorder:

(i) Exposure to high frequencies or ultrasonic sound above the audible range damages inner ear and induces nau­sea and dizziness in man.

(ii) Exposure to mid-audible frequency affects brain and nerv­ous system having significant impact on thinking and coordination of limbs.

(iii) Moderate vibration can lead to pain, numbness and cyanosis (blue coloration) of Fingers.

(iv) Severe vibration results in damage to bones and joints in the hands with swelling and stiffness.

(v) Exposure to low frequency noise can reduce heart beat, variation in blood pressure and breathing difficulties.

(b) Non-pathological disorders:

These disorders are mainly seen in industries and other establishments which result in lower efficiency, reduced work rate, increased absenteeism and a higher potential for accidents and injuries. Noise also disturbs sound sleep of old people. Children exposed to excessive noise show signs of behavioral disorder which in later age manifest them­selves in destructive nature.

(c) Vibration (physical vibration) disorder and Reynaud’s phenomenon:

(i) Noise from constant vibrations of hand tools like the hammer or drilling instrument creates ‘dead hands’ or ‘white fingers’ which is known as Reynaud’s pheno­menon.

(ii) Noise from moderate vibrations causes pain, numbness, and cyanosis.

(iii) Noise from severe vibrations causes damage to bones, joints with swelling and stiffness.

Some of the important effects of noise pollution are outlined as given below:

1. It causes contraction of blood vessels, makes the skin pale leads to excessive secretion of adrenaline hormone into blood thereby inducing high blood pressure.

2. It may cause damage to heart, brain, kidney and liver.

3. It induces contraction of muscles which ultimately leads to nervous breakdown, tension and even insanity.

4. It induces anxiety, stress and fright which in turn causes increased heart beat, constriction of blood vessels, dilation of pupil of eye etc. by modulating the hormone content in blood.

5. It damages some part of auditory system thereby causing the impairment of hearing.

6. Excessive noise causes thickening of blood and changes in breathing amplitude.

7. It is responsible for disturbing the entire biological system. For example, the internal wreckage caused by the roar of a jet engine includes gastric ulcer and thymus gland atrophy.

8. It causes irritation, dissatisfaction, disinterest and affects work efficiency.

9. Sudden and explosive sounds cause cracks in buildings and breaking of window doors and glasses.

10. It causes chronic headache and irritability thereby reducing work efficiency.

11. It brings about changes in the behavioral aptitude of birds and animals. For example, noise pollution discourages the annual visit of migratory birds to Alipore Zoo of Kolkata.

12. It interferes with communication systems. For example, sometimes it becomes necessary to raise the volume of our TV set or radio to overcome the impact of external noise.

The detrimental effects of noise with different intensity on human beings are shown in Table 10.3.

Permissible Noise Levels (Control):

We have already discussed the sources of noise of different in­tensity and their hazardous impact on living organisms particu­larly on man. Still we work and live in the environment where the noise level is not optimum. Thus it is rightly told by Robert Koch that noise pollution is a slow agent of death. The peoples work­ing in areas where the intensity of noise is comparatively higher suffer from progressive hearing loss, physiological (health) and psychological hazards including tension. The maximum permissible noise levels at different situations are summarised in Table 10.4.

3. Prevention and Control of Noise Pollution:

Noise produced from different sources has created a catastrophe to the entire living world specially to man. Hence, necessary steps should be taken to minimise the level of noise thereby protecting the living world from its detrimental effects.

Few methods of minimising noise pollution are discussed below:

(1) Industrial noise pollution control:

The level of noise pollution due to industries can be lowered down by adopting the following techniques:

(a) Use of improved technique:

The noise at source can be reduced by replacing noise producing machines with suitable improved technique. For example, the noise from exhaust fans can be decreased either by increasing the number of blades or by decreasing the rotational speed.

(b) Sound proofing:

An insulating material may be applied on the noise producing machinery and equipment’s which causes sound proofing.

(c) Transmission control:

The level of noise can be mini­mised by covering the walls of the room by sound ab­sorber (e.g. acoustic tiles), introducing gaskets around the doors and windows, sealing all the outlets and putting carpet, drapery and acoustic materials inside the room.

(d) Creation of green vegetation cover:

Plants and trees should be planted along highways, streets and indus­trial areas because the vegetation covers absorb and dis­sipate sound energy and acts as a buffer zone.

(e) Using protective devices:

The use of ear plugs or ear muffs or even cotton balls by the worker in the industry can protect them from hazardous effects of noise pollu­tion.

(f) Operations in open space:

Noisy industrial operations should be conducted at open spaces far off from resi­dential areas.

(g) Use of Building codes:

Certain codes should be en­forced which require sound proofing in the construction of industries, buildings and apartments.

2. Community noise control:

The community noise control includes minimization of noise from air traffic, transport system, building constructions etc. The noises from the above sources can be lowered by adopting the following procedures:

(a) 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.

(b) The road traffic noise includes tyre noise, engine intake noise, exhaust noise, aerodynamic noise, noise from blowing of horns etc. Such type of noise pollution can be controlled by incorporating silencers in vehicles, main­taining speed limit prescribed for the vehicle and ban­ning air horns.

(c) The loudspeakers, radio and music system should be operated at threshold intensity so that the noise level should not be hazardous to living organisms.

(d) Public awareness should be created to educate the com­mon man about the harmful effects of noise pollution, through radio, television, newspapers etc.

(e) The noise can be reduced by introduction of new regula­tions which mainly include lowering speed limits and designing for non-stop operation.

(f) Stringent laws should be implemented to control noise pollution. For example Motor Vehicle Act of India pro­vides restrictions on heavy vehicles using double sirens while passing through populated areas.

(g) The laying of ballast less tracks reduces the noise level due to railways.

(h) The noise pollution can best be controlled by promo­ting education and research.
