Essay on Noise Pollution
Meaning of
Sound or Noise Pollution:
The sound or sound
through which humans interact, animals and birds make a variety of sounds
naturally, what does not make the sound of running water bliss or whose heart
roars in the forest.
Whether clouds are
roaring or storm surge, volcanic eruptions or sea waves hitting the coast - all
these are sound. The reality is that sound originates from natural actions as
well as a means of human expression.
By this, communication
and exchange of ideas are possible and from this, sweet waves of music also
arise. But when this sound starts to sound unpleasant and undesirable and put
extra pressure on the ears, it causes pollution.
In fact, when sound
takes the form of noise, it falls under the category of pollution because it
has an adverse effect on the human brain and the senses. As Maxwell described -
"Noise is sound that is undesirable. It is a major factor in atmospheric
pollution. "
In modern
mechanical era, the ever-growing venues, industries, trains, motors and other
automatic vehicles, the sound of jets and airplanes are the cause of the noise,
today loud music, religious and social ceremonies, processions, public
meetings, etc. All are due to noise pollution.
Human beings do all
these activities for themselves, for society, for the production of
miscellaneous goods, so it does not mean that they should end all these works
and go back to the primitive systems. But many types of noise are redundant and
some can be reduced and balanced.
Therefore, proper
discussion of this problem is required so that we can become familiar with the
situation. This is a problem that is the result of urban culture, which is why
noise pollution was accepted as a problem in the Environment Seminar organized
by the United Nations in 1972, which needs to be controlled.
Measurement of
Noise and Noise Intensity:
Noise is a relative fact that is difficult to categorize on the basis of experience because some
people find 'pope' music to be loud noise while others are melodious.
Similarly, people from rural areas find the atmosphere of the city very noisy.
Therefore, it
cannot be distinguished from experience. For this reason, scientists have
developed a method for measuring sound or noise in which the predominance of
sound is measured through the reciprocal relation of energy.
The unit which is
used for measurement is called 'decibel' and the instrument with which it is
measured is called 'noise measuring device'. In decibels, the sound of the conversation is 610 decibels and the sound of 100 decibels falls in the
category of very intense.
The loudness in
loud decibels is as follows:
I. decibel 150 -
unbearable pain,
II. Decibel 140 -
suffering begins,
III. Decibel 130 -
sensation start,
IV. Decibel 110 -
Motor Horn.
In most countries,
the maximum noise range is 75 to 85 decibels. According to scientists, the
person becomes deaf after a prolonged stay under the influence of sound above
90 decibels.
The loudness of
sounds originating from various sources in decibels are as follows:
The speed of sound
or noise is relatively more in cities and less in rural areas. The rate of
noise pollution in different cities in India is 75 to 90 decibels which are not
very high, but it is relatively high in airports, railway stations, industrial
areas.
Sources of
Noise Pollution:
Sources of noise
pollution can be divided into two categories:
(i) Natural and
(ii) Human or
artificial.
(i) Natural Source:
Certain natural
activities also cause noise pollution, such as thunder clouds, lightning
strikes, stormy winds, volcanic eruptions, earthquakes, waves hitting the
seashore, water falling at high speed,
etc. These factors are regional and some have effect only in seconds or
minutes.
Also, their effect
is sometimes greater but usually not more. The sounds of wildlife also cause
noise in the quiet forest. But the effect of all-natural factors is not more
harmful than transient.
The continuous
development of industrial and transportation means, the expansion of sound by
electrical equipment, the development of various types of audio equipment and
the noise pollution caused by many human actions cause.
Human sources of
noise pollution can be divided into the following parts:
(I) by industrial
institutions,
(II) by means of
transport,
(III) by means of
entertainment,
(IV) Others.
(I) By industrial
institutions:
A major cause of
noise pollution is the noise or noise of the industry and the machines moving
in them. Today, the number of industries is increasing continuously, as well as
the size of the machines used in them is also getting bigger and larger. Noise
pollution is also becoming more due to friction of various machines used in
industries.
The noise from the
industries have the highest impact on the workers and other employees working
there as they have to continuously listen to the same while their limited noise
also affects the residents of the neighboring areas.
Not only is there
noise from large industries, but there is noise from small industries too,
especially where the work of breaking, cutting, cutting, etc. is done. The
noise pollution of the workers in the factories increases more with age. For
example, noise is not harmful up to 95 decibels for laborers below 30 years,
while for 40 to 50 years old, this limit is 84 decibels and for 50 to 60 years
of age is 80 decibels.
(II) By means of
transport:
In the current
urban civilization, modes of transport are the noisiest pollution factor.
Various modes of terrestrial transport such as trucks, buses, motorcycles,
scooters, firefighting vehicles, police vehicles, ambulance rail, etc. all
become the factors of noise pollution.
Horns, sirens, etc.
used in them cause noise. Not only this, but the noise caused by the noise of
the engine and friction of the rail due to the running of the vehicle is the
cause of the noise. On the railway platform, when the engine gives the horn,
hardly anyone avoids this pollution because it is the ear-piercing sound.
It is also known
from the experiments conducted in America that if there are no noisy sirens or
horns, then there is no difference in their services. Not only terrestrial
transport but also air transport is the major cause of noise pollution.
Especially at the
airports from where the aircraft takes off and takes off. The jet engine of the
airplane produces an agonizing noise while flying, which is 150 decibels. This
pollution has a great impact on the residents near these airports, especially
children and the elderly. At present, the number of air flights is continuously
increasing.
Their use is
increasing not only in developed but also in developing countries. Not only
this but the development of 'Super Sonic' airplanes, even more, advanced than
jets, is the reason for the further increase in noise pollution because
supersonic planes fly faster than sound in which the percussion waves are
produced. These waves produce a sudden pressure in the atmosphere that
manifests as a sonic boom or sound booke. It is also called sonic-bang, which
is 10 to 100 km. The area is wide.
(III) By means of
entertainment:
A major change in
the means of entertainment presently has been the movement of fast music through
electric means. It has become very prevalent not only in public places but also
in homes. Noise music entertains on religious festivals, social gatherings, and
noise pollution.
The more popular
pop music currently is, the noisier it is. Continuous listening to music or
other programs in loud sound on TV, radio, etc. eventually leads to deafness.
In this way, listening to music continuously by putting a device in the ear is
to invite deafness.
(IV) Other factors:
Apart from the
above mentioned major noise pollution factors, noise pollution occurs due to
many common and daily tasks.
As:
(i) running engines
for road construction,
(ii) promotion of
elections,
(iii) Religious
story-kirtan,
(iv) Use of band in
wedding festivals,
(v) Mineral Mining,
(vi)
Maneuvers by the army.
Effects of
Noise Pollution:
Noise pollution
highly affects the health of humans, animals, and properties. A few are
mentioned below:
·
Increasing
noise pollution day by day is reducing the ability and quality of human work.
·
Noise
pollution reduces the concentration level because high levels of noise cause
fatigue and fatigue.
·
It
extremely affects pregnant women and causes irritation and miscarriage.
·
It
causes various diseases (high blood pressure and mental illness) to people as
it disturbs the peace of mind.
·
The
high level of noise reduces the quality of work and thus it reduces the level
of concentration.
·
This
may cause temporary or permanent deafness as the noise level of 80 to 100 dB is
unsafe for people.
·
It
also damages the historical monuments, old buildings, bridges, etc. as it
weakens the structure by creating dangerous waves that hit the walls.
·
Animals
lose control of their brains and can be more dangerous because a high level of
noise damages their nervous system.
·
It
also affects plants and causes the production of poor quality crops.
Conclusion:
The increasing
level of sound pollution has created an urgent need for general awareness noise
pollution the sources, effects and preventive measures of noise pollution.
High-level noise should be prohibited in areas like workplaces, educational
institutions, residential areas, hospitals, etc. Younger children and students
should be motivated not to engage in high sound production tasks such as the
use of high-sounding instruments and equipment.
The use of
high-level sound-producing crackers should be minimized during occasions such
as festivals, parties, weddings, etc. Topics related to noise pollution should
be added to textbooks and programs such as lectures, discussions, etc. can be
organized in schools so that the new generation can be more aware and
responsible citizens.
Essay on Noise Pollution (400 Words)
Introduction:
The pollution of
the environment is called pollution. In today's time, our entire environment
has become unhealthful that negatively affects our body. Sound pollution is
noisier than high noise and higher sound. The noise on our wires is the noise
which increases the quantity of noise in the atmosphere and causes pollution.
Reasons for
Noise Pollution:
In today's modern
era, sound pollution is gaining momentum due to these following reasons-
·
Vehicles-
Vehicles on the roads make noise and the horns of vehicles also increase the
noise in the environment.
·
Entertainment - Radio, TV, DJ, etc also
increase noise.
·
Rally-
Loudspeakers used in rally etc. also promote sound pollution.
·
Industries-
Machines used in industries also produce high sound whose noise is unbearable.
·
There
is also plenty of noise at the time of the construction of homes and repairing
of roads.
Effects of
Noise Pollution:
The environment has
a great impact on the life of any human being. If the environment is pure, then
the person will be healthy and if there is pollution in the environment then
people will suffer losses. Following are the effects of noise pollution -
·
People
have high hearing problems because of high sound and constant walking causes
hearing disorder.
·
A
person might have problems like sleeplessness because of noise, due to that he
remains under stress and behavior also becomes irritable.
·
Hypertension
also arises due to noise pollution.
·
Due
to too much noise, children's education is also hindered and their complete
development is not possible.
·
Heart
attack complaints also increase.
Prevention of
Noise Pollution:
To keep the
environment clean and to keep humans healthy it is necessary to stop the noise
pollution for which these measures can be taken-
·
People
should not build houses on the roadside because of the noise of vehicles all
day and night.
·
The
government has also prohibited the use of horns so that contamination can be
controlled.
·
The
speed of the vehicles should also be determined.
·
The
limit of DJ playing at weddings has also been extended to 10 pm so that people
living nearby do not have trouble sleeping.
·
Stopping
the use of loudspeakers at rallies.
·
Machines
used in industries should be serviced periodically so that there is not much
noise.
Conclusion:
More noise is
harmful to health, so try to use only low-sounding instruments and reduce noise
pollution. We all have to reduce the noise pollution together otherwise, all
will be deaf in the coming time.
