INTRODUCTION
• Noise can disturb our work,
rest, sleep and
communication. It can
damage our hearing and
evoke other psychological
physiological and possibly
pathological reactions
However, because of
complexity, variability and
the interaction of noise with
other environmental factors,
the adverse health effects of
noise do not lend themselves
to a straight forward
analysis.
SOURCES OF NOISE
INDOOR SOURCES OUTDOOR SOURCES
 Air coolers
 Air conditioner
 Television.
 Music system.
 Family conflict.
 Baby crying.
 Other office and
home appliances.
 Traffic (road, rail)
 Loudspeakers.
 Vehicles horn.
 Construction
activities.
 Fire crackers.
 Industries.
 Generators.
• Noise is typically defined as
unwanted sound. Sound
which pleases the listeners is
music and that which causes
pain and annoyance is noise.
At times, what is music for
some can be noise for others.

The study area is situated in the central
Beohari having an avg. elevation of 388m
above the sea level. It is situated in between
24o00’52.6”north latitude and 81o22’46.7”
east longitude.
The noise level has been recorded at four
different observations point covering all kinds
of land use of the site. Observation point 1 is
situated near the newly constructed
residential area of the site. Observation point
2 is situated at the meeting point of cc road
and the state highway. Observation point no.
3 is situated in front of my home (shivam
traders), observation point no.4 is situated
under the block office area.

The required data for noise
assessment has been collected at four
different observation points at four
different time periods i.e. morning
(8:45-9:00), afternoon (12:15-
12:30), evening (18:00-18:15) , night
(21:00-21:15) covering all kinds of
land use of the study area. The data
for noise assessment has been
recorded in the form of different noise
levels at different time period and
different points in decibels along with
the offsite and onsite sound sources
has also been recorded.
The data collection has
been done with the
help of a mobile
application called
noise meter by jinasys.

MORNING

The measurements of noise levels have been recorded in working day (Monday 20-10-2020) at the four different
observation points at selected site in vicinity of Beohari. The analysis has revealed the following points-
 The noise pollution levels are more than the permissible limits at the observation point 2 and 3 if we consider that as a
residential area. However the other two points 1 and 4 have noise emissions under the permissible limits.
 The maximum noise levels are especially determined by the heavy traffic, technical Status of the vehicles and quality of
the road situation.
 Evening time is the peak time of the noise level for points 2, 3 and 4.the major source of noise at this time period is
the traffic on the road.
 The variation in the noise levels at the observation points is directly related to the distance between the state highway
and the location of the point and also to the sound barriers like trees and walls coming in between the noise source
and the point.
 It is suggested that the necessary abatement measures to reduce the noise levels in these areas should be
implemented in order to improve the present status of human health and environment of the study area located in the
Beohari.
RESULT

CONCLUSION
• By analyzing the data it has been found that the sound barriers like trees and walls are actually helping in reducing the noise
intensity at observation point 1 and 4.
• As compared to the other two points i.e. observation point 2 and 3 , points 1 and 4 have recorded low noise level because of the
distance from the main road and also due to the presence of various sound barriers like trees ,buildings and walls between the
state highway and the points .
•
• Only two points (2 and 3) have recorded high noise levels therefore the following measures should be taken with the aim of
reducing the noise level produced by different sources:
•
 Banning the use of high decibel horns.
 Banning the loudspeakers.
 the rehabilitation of the infrastructure of the street networks of ways with intense traffic;
 the implementation of the technical measures for noise levels;
 Creating noise barriers alongside the road like trees and walls. Or grass walls.
 blocking the ways of noise propagation by creating protection curtains, including green spaces within inhabited areas;
 Performing special isolation for buildings against one or more types of environmental noise combined with ventilation or
conditioned air facilities, in order to maintain high values of the isolations against environmental noise.
