today I'm going to discuss another
important topic from environment that is
noise pollution sources impact and
mitigation myself Dr indrajit ruri
assistant professor Department of
geography and applied geography
University of North Bengal now what is
noise
pollution now the word noise is
basically derived from the Latin word
nosia which means sickness in which one
feel the need to vomit that means when
there is a situation is been coming up
in your health that something is not
being good or something not being
happening to you which is which is
impacted on your health that is
basically the disbalanced situation in
your health now regarding the noise
pollution when a obviously we have a
capacity to hear the sound with with our
ear okay so the main important thing
regarding the noise pollution that means
the sound which we are trying to able to
get through our ear obviously when the
level of the noise is too high then it
talks about the pollution so noise is
the unpleasant and undesirable sound
which leads to discomfort in the human
beings now intensity of sound is
measured by in the noise pollu noise
basically it is measured by the decibel
which is being denoted by small D and
capital B decibel so the fous sound that
are human ear can hear only up to 1 deel
1 dcel up to 1 dcel we able to hear the
sound but more than 1 dcel definitely
that can be the pollution and as well as
the civilization is being increasing the
urbanization is been increasing so that
is basically responsible for the noise
pollution so if I'm talking about the
more number of vehicles on the road the
honking the horn aircraft industrial
machineries then the firecrackers
everything are being responsible for the
noise pollution okay so this is the main
concept or the definition of the noise
pollution coming to what are the
different types of noise pollution first
is the transport noise so it mainly
consist of traffic noise which has
increase in recent years with the
increase in the number of vehicles so
more number of vehicles more honky the
more honking situation is going on so
more noise is been coming up so the
increasing noise pollution leads to the
defining of the older people the old age
people as well as it is responsible for
the headache and hypertension second
type of noise pollution that is called
the neighborhood noise so the noise from
gradates household utensils Etc that is
also been the sources for the noise
pollution even if we are using using the
musical instrument we are using the
sound box we are using the transistor we
are using the loudspeaker that is also
responsible for the noise pollution
another type of sources that is called
the industrial noise obviously high
intensity sound which are been coming
from the industries
machinaries that is also responsible for
the noise pollution so according to many
research a lot of work have already been
done on the noise pollution so
industrial noise pollution are mainly
the responsible fact or the facets for
the uh particular industry is the main
sources for the noise pollution and it
is almost 20% of the issues are been
coming from the industrial noise
pollution now what are the causes and
sources of noise pollution first of all
obviously there are several causes and
sources of noise pollution number one
the industrialization it has led to an
increase in noise pollution as the use
of heavy machineries such as generator
meals huge exhaust fan are being used
resulting in the production of unwanted
noise even the vehicles the vehicles
which have been flying on the city roads
that is also responsible for the noise
pollution so this is the second reason
for noise pollution even the events like
the election is going on so rallies
events or meeting all this situation is
going on the road so even the wedding
ceremony or the social or even kind of
cultural program any kind of gathering
public use a loudspeaker so that
loudspeaker also playing the music and
the sound so that is also responsible
for the noise pollution next is the
construction sites mining construction
of building that is also adding the
noise pollution if I'm talking about the
noise pollution example obviously there
are some of the examples of noise
pollution first of all the unnecessary
usage of horns in the roads next is the
using louds speaker either for the
religious functions or for the political
purposes unnecessary uses of the
fireworks even during Festival time
whenever we are using the firecrackers
that is also responsible for the noise
pollution those people we are living in
the city area we we are experiencing
this kind of noise pollution next is the
industrial noise construction noise even
the noise from the Transportation such
as a railway and the aircraft now what
are the effects of noise pollution on
human health noise pollution can be a
hazardous on the human health in the
following ways first of all the
hypertension hearing loss sleeping
disorder cardiovascular diseases these
are the issues encompasses with the
noise pollution so H if I'm talking
about the hypertension now it is a
direct result of noise pollution which
is caused due to elevated blood levels
for a longer duration hearing loss that
is also responsible due to the noise
pollution the constant constant exposure
of human ears to loud noise that are
beyond the range of sound that human
ears can with withstand damages the a
drums resulting in loss of hearing so
that is the issue when we are talking
about a children like 0 to 5 years of
age they are mostly affected by this
kind of hearing loss because they have a
problem of this noise because those
people are living in the urban areas
most of the time they are experiencing
with this noise pollution sleeping
disorder lack of sleep might result in
fatig and low energy level throughout
the day affecting everyday activities
noise pollution hampers the sleep cycle
leading to irritation as well as the
uncomfortable State of Mind even if I'm
talking about the cardiovascular issues
heart related problems such as blood
pressure level stress cardiovascular
diseases it also might come due to the
noise pollution and even if I'm talking
about the individual person who are
suffering from any kind of diseases that
is also a certain issues of the noise
pollution now what are the preventions
what are the mitigations or measure that
we are taking for controlling the noise
pollution so first of all honking in
public places like teaching institution
school college universities even the
hospitals which are called as a silence
zone so that area we should stop or
Banning the noise pollution because we
are not being honking the sound second
in commercial places even in the
hospital areas and the industrial
buildings adequate soundproof system
should be installed so that the outer
sound should not be entering into the
building as we know that most of the
hospitals is located near the main road
and this noise pollution cannot be
control because vehicles are flying on
the roads so automatically it comes huge
amount of sound so we should be able to
construct a soundproof system of a
building the wall so that the outer
sound may not be come into the inner
part of the room next is the musical
instrument sound should be controlled to
the desirable limit that means the limit
up to we
listen Den treover is very much useful
in the noise pollution prevention next
one is the explosive should not be used
in the forest even mountains and even
the mining
areas if I'm talking about the
categories of the areas where the noise
limits is being maintained by the cpcb
which is called as a central pollution
control board so these are the four
categories of areas first of all the
industries areas commercial area
residential area and the silence zone
now under the categories of the
industrial area in the daytime because
we are measuring it is in the decibel DB
so in the day time the limit of the
sound that should be 75 D but in the
night time that should be reduced
because it is a sleeping time so that
should be 70 D in the commercial area
the limit of the sound or the decel that
is in 65 D in the daytime but if I'm
talking about the night time it should
be 55 D regarding the residential area
55 D we should be maintained during
daytime 45 D we should maintain in the
night time if I'm talking about the
silence Zone in the daytime it should be
50 but in the night time it should be 40
what should the daytime is being
considered by the central Pollution
Control Board the time duration from
6:00 a.m. in the morning to 10:00 p.m.
in the night and the night time should
be considered obviously after that 10:00
p.m. to 6:00 a.m. in the morning what
would be the silence Zone silence zone
is defined as a area up to 100 m around
such premises as hospitals education
institution and courts to the silence
zone are to be declared by the competent
author
use of vehicular horns loudspeaker and
bursting of crackers shall be banned in
these journals mixed categories of area
should be declared as one of the four
above mentioned categories by the
competent Authority and the
corresponding standard shall apply
coming to the noise prevention act
obviously just like a air pollution we
should also follow some of the ACT First
Act should be that is article
51a what is that what is the main
objective of this article 51a just to
protect and improve the natural
environment including forest lakes
rivers and Wildlife and to have
composion for living creatures next St
should be incomp that is called the
article 48a what would be the main
objective of this article 48a protection
and Improvement of environment and
safeguarding and Wildlife the state
shall Endeavor to protect and improve
the environment and to safeguard the
forest and wildlife of the country
even we are also talking about the
criminal procedure code and the noise
control provision under the section 133
of the criminal procedure Court in 1973
the magistrate has the power to make the
conditional order requiring the person
causing nuisance including that of noise
to remove the nuisance even the railway
act 1880 that is also very crucial uh
particular way to control the noise it
is very surprising to that the railway
engines and the carriage as a big
sources of noise even India Railway
locomotive enjoy statutary protection
under the Indian then Railway act 19
1890 so this kind of act should be
incorporated to control the noise next
is the aircraft act
1934 that is also impact of the civil
aviation on the environment is evident
in the rising public concern regarding
noise which is most irritating and the
most responsible element for the
increasing Lo level from aircraft and
finally finally motor vehicle act and
noise control very importantly motor
vehicle act 1939 under Section 20 21
4168 68 681 70 and 91 uh that can be the
empowered in the state government not
only that that rule should be
incorporated to maintainance the motor
vehicles and the trailers so these are
the some of the noise prevention act
which can be incorporated to control the
noise so that is the overall discussion
of the noise so what we are discussed
definition of noise then the types of
noise what are the sources of noise
impact of noise and how to mitigate the
noise pollution so this topic and this
is a burning topic which are definitely
going to trust in the Environmental
Studies so thank you thank you very much
