Thesis irfan BY Muhammad Fahad Ansari 12IEEM14fahadansari131
This document summarizes a thesis written by Muhammad Irfan on road traffic noise pollution and remedial measures in Multan City, Pakistan. The thesis measures noise levels and traffic flows at 12 busy intersections in Multan. It finds that average noise levels exceed national standards. Major noise sources are rickshaws, pressure horns, and improper silencers. A public opinion survey finds most residents and traffic police are annoyed by high noise. The thesis concludes standards are insufficient and recommends banning pressure horns and enforcing vehicle emission standards, while designating hospitals and schools as silent zones.
Traffic Noise – A Health Stressor for MankindIJSRED
This document summarizes a research paper about the health effects of traffic noise pollution. Some key points:
- Traffic noise pollution has increased significantly with rising vehicle numbers and congested roads in cities.
- Prolonged exposure to noise levels over 55dB can cause health effects like hypertension, increased stress, and potential hearing loss.
- Noise pollution is linked to cardiovascular diseases as well as mental health impacts like disturbed sleep and changes in mood.
- Studies estimate thousands of premature deaths per year in Europe are caused by noise pollution from traffic and other sources. It is a major contributor to the disease burden in cities.
- More research is still needed on the long term health impacts of early life exposure to noise pollution
Pollution Due To Noise from Selected PlacesIOSR Journals
Noise pollution degrades environment and also causes health hazard to human beings. In urban areas major sources of noise pollution are traffic and construction activities. Available guide lines for noise pollution have been reviewed in the paper. Measurement of noise levels at selected locations reported in the paper, for example, railway stations, use of machinery at construction sites, etc., was made and compared with the guide line values. It has been observed that the noise level at all locations exceeds the value prescribed by the competent authorities. At the pedestrian locations the noise level is 60 dB to 110 dB. At the railway crossing the noise level is 45 dB to 110 dB. The above inference shows that the noise pollution is paramount at all sources. Due to the various adverse impacts of noise on humans and environment, noise should be controlled. The conclusion drawn from this study is that the technique or the combination of techniques to be employed for noise control depends upon the extent of the noise reduction required, nature of the equipment used and the economy aspects of the available techniques
This document discusses noise pollution from various sources such as road traffic, construction activities, and aircraft. It provides examples of how noise pollution affects communities and individuals. It also presents two case studies, one analyzing traffic noise levels in Kolkata, India that were found to exceed standards, and another describing how military sonar caused the death of beached whales by disrupting their communication. Noise pollution is shown to impact human health and behavior as well as wildlife.
The document discusses noise pollution, including its sources, effects, and regulation. It defines noise pollution as unwanted sound that disrupts normal activities. Major sources include airplanes, road traffic, construction equipment, and industrial machinery. Noise pollution can cause hearing loss and disturb sleep. Indian law regulates maximum noise levels in different zones and restricts use of loud speakers and vehicles. Individual actions like observing car-free days and using barriers can help mitigate noise pollution.
IRJET- Effect of Noise on Human Psychology in Public Spaces of Dhaka CityIRJET Journal
The document discusses the effects of noise pollution on human psychology in public spaces in Dhaka, Bangladesh. It measures noise levels at five public locations and interviews people at each location about the psychological impacts of noise. The study finds that noise from vehicles, crowds, and hawkers causes health issues like headaches and stress responses. Extreme noise is linked to problems like irritation, anxiety, and sleep disturbances. The busiest locations of Farmgate and Mirpur 10 have the highest noise levels and most reported psychological effects.
Road traffic is a major source of noise pollution, especially near busy roads. Factors that influence traffic noise include vehicle type and speed, road surface conditions, and tire-road interactions. Exposure to high levels of traffic noise can cause annoyance and disrupt sleep and activities, and long-term exposure is linked to physiological health effects. Recommendations to reduce traffic noise pollution include constructing sound barriers, limiting vehicle speeds, altering road surfaces, restricting heavy vehicles and smooth traffic flow. Computer models can help identify cost-effective strategies to mitigate noise when planning or expanding road projects.
Noise pollution is the introduction of unwanted or disturbing sound that disrupts normal human or animal activity. It comes from sources like transportation, construction, industrial machinery, and loud music. Noise pollution can negatively impact human health by causing hearing loss, cardiovascular issues, and impaired mental health. It affects animals by damaging their nervous systems, interfering with communication and navigation, and reducing usable habitat. Solutions include controlling noise at its source, reducing transmission through barriers and insulation, and protecting receivers with equipment or planning.

Environmental noise pollution from road transport and other sources in varna,...eSAT Journals
Abstract The present research has been conducted in Varna – the third biggest city in Bulgaria in order to assess the environmental noise pollution from road transport and other sources. Noise monitoring has been done during the period 2007-2014 at 45 monitoring posts situated at: areas with intensive road traffic; areas with railroad traffic; areas with aviation noise; areas with marine traffic; industrial areas; built-up areas; recreation areas; hospitals and sanatoria; scientific research sites; quiet areas in open country. The noise pollution has been assessed through the daily equivalent sound levels LeqD in the environment that determine the degree of discomfort during daytime (07.00 – 19.00). Research results have been statistically interpreted by variation analysis and the differences have been estimated by Student-Fischer t-criteria. The dominant source of environmental noise pollution in Varna is road traffic. Sound levels at monitoring posts with intensive road traffic are considerably higher than the established limit value – LeqD vary between 69.28 and 71.72 dB(A) and exceed the limit value with 10-12 dB(A). At recreation areas the average LeqD exceed the limit value during the entire monitoring period. More intensive noise pollution has been observed from 2010 onwards as the increase is statistically reliable and the differences are of strong statistical significance (0.001 ≤ Р ≤ 0.05). At built-up areas the average LeqD are close to the limit value and a statistically reliable increase has been registered from 2010 onwards (P < 0.001). Different types of measures are discussed to reduce noise pollution mostly from road transport. Key Words: daily equivalent sound level, environmental noise pollution, noise sources, road traffic

Sanchit Gupta's document discusses noise pollution. It defines noise pollution as unwanted or disruptive sound that affects human or animal life. The main sources of noise pollution are identified as household appliances, social events, commercial and industrial activities, and transportation. Effects of noise pollution on health include increased heart rate, blood pressure, and risks to respiratory and digestive systems. Reducing noise pollution requires new technologies, traffic management, public awareness, and designated noise zones.
Noise pollution disrupts human and animal life and comes from sources like construction, transportation systems, and urban planning. It can cause health issues for humans like hypertension, hearing loss, and sleep disturbances. Noise pollution also negatively impacts wildlife by interfering with communication and increasing predation risk. Prevention strategies include noise barriers, limiting vehicle speeds, and controlling heavy traffic to reduce noise.
This document discusses noise pollution, its sources, effects, and control measures. It defines noise pollution as unwanted sound that penetrates the environment. Major sources include industrial noise, transport noise, and neighborhood noise. Noise pollution can cause health issues like headaches, hearing loss, and cardiovascular problems. It also affects animal life and disturbs human communication and quality of life. The document outlines noise standards for different areas and vehicles in India. It recommends control measures like planting trees, regular vehicle maintenance, hearing protection, soundproofing buildings, and raising awareness.
Noise pollution is defined as unwanted, disturbing or harmful sound that impairs hearing or causes stress. It can be caused by transportation like vehicles and aircraft, industrial and construction machinery, and loud consumer products. Prolonged exposure to sounds over 85dB can cause permanent hearing damage. Noise pollution has negative health effects like disturbed sleep, cardiovascular issues, and hearing loss in both humans and animals. It also negatively impacts plants and animal communication. Methods to reduce noise pollution include modifying noisy sources, adding barriers, limiting vehicle speeds, and interior plants.
1) Noise pollution occurs when unwanted sound disrupts normal activities like working or sleeping. It is caused by both industrial sources like machines as well as transportation sources like vehicles.
2) Common sources of noise pollution include industrial noise from factories, transport noise from vehicles, and neighborhood noise from household items and community events.
3) The health impacts of noise pollution include high blood pressure, stress, sleep disruption, and hearing loss. It can also negatively impact wildlife that rely more on sound.
Noise pollution comes from both natural and human-made sources. Natural noise sources include insects, birds, animals, thunderstorms, waves and winds. Human-made or anthropogenic noise sources are classified as either mobile sources like transportation, vehicles and aircraft, or stationary sources such as industrial operations, construction activities, and gas stations. Noise pollution is measured in decibels and can cause health issues for humans and other living creatures when sound levels are too high.
Noise pollution is caused by traffic, airports, trains, children playing, phones, televisions, and ships. It is a problem everywhere due to activities like coal mining and airport operations. Solutions include restricting vehicle horns, educating the public, imposing fines, and properly managing urban development to reduce noise pollution and protect human and animal hearing.
Noise pollution is excessive noise that harms humans and animals. Outdoor noise is mainly caused by transportation systems like vehicles, aircraft and trains. Indoor noise comes from machines, construction and music. Noise pollution can cause hearing loss, cardiovascular issues, stress illnesses and disrupted sleep in humans. It raises risks of death for animals by interfering with communication, navigation and reproduction. Reducing noise pollution involves soundproofing noisy machines, restricting horn use and loud vehicles/areas near homes, and planting trees to absorb sound.
The document discusses various aspects of noise pollution in India including sources, effects, regulations, and legislation. It provides an overview of ambient noise levels from road traffic and air traffic in Delhi, noise standards specified under environmental laws, and sections of various acts that govern noise pollution control such as the Environmental Protection Act, Air Act, Motor Vehicles Act, and Factories Act. It also outlines issues related to noise from traffic, generator sets, industries, loudspeakers, and construction activities.

Elliptic Fourier Descriptors in the Study of Cyclone Cloud Intensity PatternsCSCJournals
Cyclone cloud intensity analysis is conducted to study the evolution of a cyclone storm mainly using two approaches, namely: wind field analysis and pattern recognition. Of the pattern recognition based approaches , the Dvorak technique has been a pioneering effort which is widely used today. However, the Dvorak technique is subjective, as it relies on human judgment and is, therefore, error prone. Efforts have been described in the literature to automate the classification process. In this paper, we describe our efforts to perform a semi-automatic computer analysis of the cyclone cloud intensity evolution pattern which compares preprocessed visible (VIS) and enhanced infra-red (EIR) satellite images with the corresponding prototype Dvorak patterns using Elliptic Fourier Descriptors (EFD) and Principal Component Analysis (PCA) techniques. This novel approach is simple and intuitive and is robust to noise, and at the same time provides classification in cases where the cyclone exhibits fluctuations during its evolutionary cycle.

Bangladesh is a densely populated country located in South Asia that gained independence from Pakistan in 1971. It has a population of over 141 million people within a small land area, making it one of the most densely populated countries. Bangladesh is also cyclone prone and has experienced devastating cyclones in the past, including the Bhola Cyclone in 1970 that killed over 125,000 people and Cyclone Gorky in 1991 that killed 138,000 people. The most recent major cyclone was Cyclone Sidr in 2007, which formed in the Bay of Bengal and made landfall in Bangladesh as a Category 4 storm, bringing high winds and storm surges that impacted the low-lying delta region.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Common types of pollution include water, air, noise, soil, and thermal pollution. Water pollution can come from sewage, industrial and religious waste being dumped into rivers like the Ganges and Yamuna in India. Air pollution levels are high in many major Indian cities due to vehicle emissions and industrial activities. Noise pollution is widespread in residential areas near roads and industries. Soil pollution occurs from dumping of domestic, industrial and agricultural wastes. Thermal pollution of water bodies is caused by the discharge of hot water from industries like power plants.
The Kashmir earthquake occurred on October 8, 2005 at 08:50 UTC in Pakistan-administered Kashmir with a magnitude of 7.6. It caused widespread destruction, killing over 73,000 people in Pakistan, 1,400 in India-administered Kashmir, and 4 in Afghanistan. The high death toll was due to most people being in homes and schools during the earthquake, as well as difficult terrain hampering relief efforts.

Methods for abating air pollution include removing particulate matter mechanically and absorbing or adsorbing gases. Noise pollution, its measurement, impacts, and major sources like traffic and construction are reviewed. India's noise pollution laws and standards are summarized. Vehicular pollution is a significant contributor to air pollution in cities and is
The document discusses pollution of the Ganges River in India. It provides background on the river's importance in Hinduism and as a source of life. The river is now heavily polluted due to population growth, urbanization, and industrial/agricultural waste. Studies over the decades show increasing pollution levels, with the most recent finding that Ganges water at Haridwar exceeds standards for drinking, bathing, and agriculture due to high coliform levels from human and industrial waste. The river's holiness has not prevented overuse and pollution that now threatens its ability to support life.
The document discusses the causes and effects of marine pollution. It outlines several major sources of marine pollution including land-based runoff from agriculture and development, shipping activities, disposal of plastic waste, and offshore oil drilling. These pollution sources introduce excess nutrients, sediments, toxic chemicals, and invasive species into oceans. This causes problems like algal blooms, dead zones, entanglement and ingestion of plastic by wildlife, contamination of seafood, and damage to coral reefs. Climate change is also exacerbating issues like ocean acidification that threaten marine ecosystems.

Performance analysis of cmos comparator and cntfet comparator designeSAT Publishing House
This document summarizes a study comparing the performance of CNTFET and CMOS comparator designs. CNTFET comparators were simulated using CADENCE showing faster propagation delays, lower power consumption, and improved transient response compared to CMOS comparators. Specifically, the CNTFET comparator had a rise time of 142.1ns versus 1.03ns for CMOS, and fall time of 164.18ns versus 821.476ns for CMOS. Average power was also lower at 118mW for CNTFET versus 910mW for CMOS. Due to these advantages, CNTFETs may replace silicon transistors as the performance of silicon MOSFETs reaches scaling limitations.

Noise Control Stratagies in Reinforced Concrete BuildingsIJRES Journal
This study is aimed at bringing out the salient aspects of building noise control. An analysis has been carried out with respect to the noise transmission as well as the characteristics of noise inside buildings. The key issues on building noise control have been included and discussed. A comprehensive study on building noise and on acoustically divisible spaces has been made. It has been observed that a sound insulation of the order of 30 to 35 dB is possible in a given building. Further, the noise propagation parameters in an exhibition hall have been theoretically estimated. The data so obtained has been compared with actual SPL measurements and recorded. Variations in noise levels observed have been explained. Before the partition is made, the SPL drop is faster inside the building but after the partition the drop falls at the rate of 3dB for doubling the distance. The cost of the acoustically divisible partition wall is found to be very high, but the advantage of this partition seems to be creating acoustically divisible spaces where in one can conduct two programs simultaneously, without any disturbance to each other. Prior to the selection and design of control measures, noise sources must be identified and the noise produced must be carefully evaluated.

Abstract
Noise generally is known as unwanted and unwelcome sound. It is considered as the most pervasive pollutant besides the emission
pollutants. Along with the increasing degree of air and water pollution, noise pollution is also emerging as a new threat to the
inhabitants of Chidambaram town. Noise pollution generated from vehicles with its influence on life quality and the environment may
be considered as a hot topic in scientific research and one of the main concerns of the world, especially in urban areas. Motorized
traffic is one of the major sources of noise pollution in urban areas. Ambient noise level monitoring was carried out at various
locations of the Chidambaram town during 2011(September –November).The data obtained was used to compute various noise
parameters, namely equivalent continuous level (Leq), Noise pollution level (Lnp), Noise climate (NC), Percentile noise levels (L10, L50,
L90).The comparison of the data shows that the noise levels at various locations of the Chidambaram town are more than the
permissible limits. Vehicular traffic and air horns are found to be the main reasons for these high noise levels. This study examines the
problems of reduction of individual's efficiency in his/her respective working places because of road traffic noise pollution in
Chidambaram due to rapidly growing vehicular traffic. This paper deals with monitoring of the disturbances caused due to vehicular
road traffic interrupted by traffic flow conditions on personal work performance. Traffic volume count and noise indices data were
collected simultaneously at ten selected sites of the town. The noise level values for exceeded the standards set by the central pollution
control board.
Index Terms: Ambient noise, level, Noise pollution, Noise climate, dB (A) decibel, Vehicular traffic.

1. INTRODUCTION
Chidambaram is an ancient famous temple town of the Lord
Nataraja (Siva) in Hindu, Religion. It is most important holy
and pilgrimage center attracting tourists, coming from all over
India and Abroad. The town is named after the temple called
“Chit Saba”. On the other hand, Chidambaram (i.e. Music
Hall or Hall of wisdom) The temple Nataraja was built during
the 6-8th
centuries after which it was historically influenced
and place of sanctity of divine Lord Siva by devoting service
of Chola, Pandya, and Vijayanagara Kings during their
regime. The Saivate Saint Thiru Manickavasagar, who visited
this place and made miracles, fascinating public in the part of
divinity, enlightened the Shine of divine Sanctity. This town
is called “Thillai as sung in Saiva Puranas. Since the place
was Thillai forest and in later stage it is called as Margali
(December) is celebrated every year, fascinating devotes from
all over India and abroad. The temples
at Kalahasti, Kanchipuram, and Chidambaram all stand on a
straight line at 79' 45" east longitude.
The Chidambaram temple houses the Akasha Lingam of Shiva
and is considered one of the greatest Shiva Temples of Tamil
Nadu. Chidambaram hosts the most ancient set of the
108Karana stone carvings, the key dance movements of
Nataraja. The temple complex is spread over 40 acres
(160,000 m2) in the heart of the city. Many thousands of
devotees come to this auspicious temple to pay homage to the
dancing Siva. The temple houses the Shiva and Vishnu in the
same complex, where a devotee can have darshan of Lord
Shiva and Lord Govindaraja (Lord Vishnu) from a single
place. The Govindaraja temple is also among the 108 dhivya
desams of Vaishnavites. The famous Natyanjali festival is held
in the Nataraja temple complex every year during Maha
Shivaratri. Bharatanatyam dancers from different parts of the
world offer their prayers to Lord Nataraja and perform in the
temple complex.
Noise is an unwanted sound experienced and it is a common
condition in Lagos metropolis. An important factor for the life
quality in urban centres is related to the noise levels to which
the population is submitted. Several factors interfere with the
amount of noise pollution throughout the city. A major
challenge is the quantification of the noise effects on the
population. Growth in terms of economic, social development
and population increases the tendency towards increasing
noise generation. Considering the connectivity of vicinity,
transport routes could result to an increase in noise volume
generated. Noise is considered a growing health threat,
Hardoy, J.E. Mutlin D., and Satterrhwaite, D. (1992) and
if, left unchecked could result to hazardous conditions. In the

face of unplanned traffic route control, there is an increase in
density of traffic, and a resultant increase in noise level
(Sukru, 2006). Various land use activities along these routes
contribute to vehicular noise generation. Considering that a
significant number of these routes are within residential areas,
there is the possibility of people at risk of the silent killer
called noise. Noise pollution can be considered as an
environmental hazard. Noise generally is an unwanted sound
effect. The noise originates from human activities, especially
the urbanization and the development of transportation and
industries. However, the urban population is much more
affected by such pollution; however, small town/villages along
roadsides or industries are also victim of this problem. Noise
is becoming an increasingly omnipresent, yet unnoticed form
of pollution even in developed countries. According to
Birgitta and Lindvall (1995), road traffic, jet planes, garbage
trucks, construction equipment, manufacturing processes, and
lawn mowers are some of the major sources of this unwanted
sounds that are routinely broadcasted into the air. Though
noise pollution is a slow and subtle killer, yet very little efforts
have been made to reduce it. Noise, along with other types of
pollution has become a hazard to quality of life all over the
world. Kiernan (1997) finds that an even relatively low level
of noise affects human health adversely. It may cause
hypertension, disrupt sleep and hinder cognitive development
in children. The effects of excessive noise could be so severe
that, there is either a permanent loss of memory or a
psychiatric disorder (Bond, 1996). Thus, there are many
adverse effects of excessive noise or sudden exposure to noise.
The generation of noise is from various sources especially in
an urban environment. From industrial to occupational,
generation can be at a peak at proximity to airports and
national or local authorities to provide an acceptable noise
environment for their specific conditions normally devise
transport routes especially at T-junctions and bus stops along
major transport routes (Chigboh, 2006) .Environmental noise
exposure standards and legislation. The standard guideline for
the control of noise states that residential institutional and
educational institutions should not be over 55dBA between
7am and 11pm and 45dBA between 11pm till 7am, while
industrial and commercial exposure should not be over 70dBA
all time (IFC,2007). In some places, these standards are
usually not complied with, especially in major urban centre’s,
exposing people to the risk of noise discomfort. A report
published by Stockholm University for the World Health
Organization in 1995 has concluded that noise levels outside
dwellings should not exceed 55dB(A) to protect the majority
of people from being seriously annoyed, and that 50dB(A)
should be considered the maximum desirable. In 1999, the
World Health Organization concluded that the available
evidence showed that noise has been associated with
cardiovascular health problems, and there is a relationship
between long-term noise exposure above 67-70 dB (A) and
hypertension. (Berglund B. Lindvall, T. Schwell, D. (1999).
Noise is derived from the Latin word "nausea" implying
'unwanted sound' or 'sound that is loud, unpleasant, or
unexpected'. The noise originates from human activities,
especially the urbanization and the development of transport
and industry. However, the urban population is much more
affected by such pollution; however, small town/villages along
side roads or industries are also victim of this problem. Noise
is becoming an increasingly omnipresent, yet unnoticed form
of pollution even in developed countries.
1.1. SOURCES OF NOISE POLLUTION
Noise disrupts the tranquility of the environment and can
affect climate and human health negatively. Amongst the
common sources of noise pollution that contributed directly to
climate change are:
(a) Electricity Generating Plant
Electric energy occupies the top grade in energy hierarchy as
it finds innumerable uses in homes, industry, agriculture, and
defense and of course in some nations, transportation.
Nigeria's electricity power situation is very poor because of
erratic power supply. As a result, there is an upsurge in the use
of electricity generating plant with its attendant noise pollution
on the environment and human health. Most workplaces and
homes use generating plants 24 hours in alternative to power
supply (Akinbulire et. al 2007). The noise from generating
plants in Nigeria couples with its accompanying smoke
emission to the sky has greatly contributed to the breaking of
the ozone layer in the sky (Olokooba, S.M et al 2005).
(b)Vehicular Traffic
Increase in vehicular traffic is also a source of noise pollution
around the globe especially in most urban cities around the
world. The situation is getting seriously alarming with
increase in traffic density on city roads (ibid). The emissions
of smoke from cars are of great concern to the changes we are
currently experiencing in the climate of this country and that
of the world in general.
(c) Construction /Industrial Noise
To meet the demands of the necessity of living, the
construction of buildings, highways, and city streets causes a
lot of noise. Pneumatic hammers, air compressors, bulldozers,
loaders, dump trucks, and pavement breakers are the major
sources of noise pollution in construction sites all emitted one
classes of smoke or another, which are all contributing to the
current changes in climate (ibid).
(d)Household Noise:
Household equipments such as vacuum cleaners, mixers and
some kitchen appliances are noisemakers of the house.
Though they do not cause too much of problem, their effect of
noise emitted on human health cannot be neglected.

Furthermore, noise can be generated from neighborhood noise
consisting of neighboring apartments and noise within one's
own apartment (Niemann H et al 2009).
2. PREVIOUS WORK
Thangadurai N, etc.al (2005) discussed the results obtained
in a study on environmental noise pollution in the city of
Salem. Road traffic noise has been a major contributor to the
annoyance, which is substantiated by the result of continuous
monitoring of noise equivalent levels (Leq) at a number of
silence, residential, commercial, industrial zones and road
intersections.Tiwari Divya et.al (2005) Paper assesses the
intensity of noise in different zones of the Kanpur city. A
critical perusal of the data obtained with the mandatory values
revealed that most of the zones surveyed are under the threat
of noise menace. Paper also refers the legal options available
to counteract this menace.
Jeba Rajasekhar RV, etc.al (2005) estimated either noise
levels exceed or are about to cross the permissible standards at
most of the sampling sites of current concern in the city. In
addition, a simple noise model in the current assessment
predicts the ambient noise level Leq and the predicted values
are compared with the experimental noise levels. As the
predicted values are in reasonable agreement with the
estimated values of noise levels, it can be concluded that the
modeling equations of present study can be used to predict the
noise levels all over the city.
Pachpande BG, et.al (2005) reported that the hearing status
and audiometric analysis of school teachers and students was
collected from the schools located in the near vicinity of NH-6
passing through Jalgaon city. About 84% teachers and 92%
students have reported hearing difficulty in the questionnaire.
In the audiometric testing mild hearing loss (25 to 35 dBHL)
was observed in both the subject groups. The strategies need
to adopt for protection of the teachers/students from the noise
exposure are suggested.
Banerjee D, etc.al (2006) revealed that nighttime noise levels
(10.00 pm - 6.00 am) in all the locations exceeded the limit
prescribed by Central Pollution Control Board. The daytime
noise level was much higher at all locations in respect to the
nighttime noise level. The Day-Night equivalent noise level
(Ldn) was determined and ranged between 67.16 dB (A) and
89.44 dB (A).Kisku GC, etc.al (2006) Studied 12 locations
with sound level meter to assess day time and night time noise
levels of Lucknow city. In residential areas, noise ranged
between 67.7 to 78.9 and 52.9 to 56.4; in commercial cum
traffic areas 74.8 to 84.2 and 68.2 to 74.9 and in industrial
areas 76.9-77.2 and 72.2-73.1 dB (A) during day and night
time respectively, Values were higher than their prescribed
standards, which may pose a significant impact on quality of
life.
Thakur Gulab Singh, etc.al (2006) discussed the results of a
study undertaken to assess the noise levels at the major traffic
junctions and community area near an educational institution
of an urban city. Noise equivalent level Leq and the statistical
levels L10, L50, L90 were measured in the neighborhood
community areas as well as at the traffic junctions. The study
indicates a need for proper land-use planning when traffic
corridors are built in the silence zone areas.
3. MATERIALS AND METHODS
Noise measurements was carried out in eight locations of
Chidambaram town representing silent, commercial and
residential zones using YF-20 sound level meter. Noise levels
were measured at Chidambaram bus stand, Pachaiyappa
School, South Car Street (National shopping complex), West
car street (Kanchi thotti corner), Sirkazhi main road,
Omakulam, O.P.Road (Near Medical College),Government
Hospital, Government Higher secondary school and
Annamalai university campus. Pachaiyappa School,
Government Hospital, Government Higher secondary school,
and O.P.Road (Near Medical College) represented the silence
zone. Chidambaram bus stand and South Car Street (National
shopping complex) and West Car Street (Kanchi thotti corner)
were selected for the present study to assess the noise level of
commercial zone. Commercial zone is fully occupied with
several types of business establishments. Sirkazhi main road,
Omakulam, and Annamalai university campus represented the
residential area for the study. Initial assessment was made at
all the locations by recording sound pressure levels for ten
hours (10.00AM to 08.00PM) at the interval of one hour in
each location.
The present investigation on evaluation and analysis of
environmental noise pollution was conducted in the town of
Chidambaram during the period of winter season (September
to November). Table 1 shows the data on Chidambaram town
in context to demography, geographic locations and
meteorological aspects during the course of study. Table 2 and
Figure 1 depict the ten sampling locations/zones of
Chidambaram town that were selected for noise pollution
study. The meter was held 1.3 to 1.5 m above the ground
surface and 3.0 to 3.5 m away from reflecting surface, if any.
For each sampling location, noise measurements were carried
out continuously for the period of ten days with eight hours of
monitoring per day with a gap of one hour after every hour of
reading. The schedule selected during the day time was as
follows: morning 10.00-11.00 a.m.,11.00a.m-12.00noon,
afternoon 12.00-1.00 p.m.,1.00-2.00p.m., 2.00-3.00 p.m.,3.00-
4.00p.m., evening 4.00-5.00 p.m., 5.00-6.00p.m.,6.00-7.00
p.m. and 7.00-8.00p.m. The night readings acted as a control.
For each hour, the noise levels were recorded after every two
minutes (i.e. 30 readings were recorded every hour). So
several numbers of primary raw data were obtained in one
spot itself. Obtained raw data were pooled together and
classified as morning, afternoon, and evening sound levels.

The data collected from each location was processed for
statistical analysis. All the noise monitoring experiments were
carried out under ideal meteorological conditions. Selected
sampling locations for noise pollution monitoring in
Chidambaram town is given in the table 2.

Average, maximum, and minimum values were calculated and
compared with standards prescribed by the Central Pollution
Control Board. To measure the environmental noise levels and
to assess the noise pollution in the Chidambaram town
predominantly due to traffic mobility, the standard procedure
using calibrated sound pressure level meter was used. This
instrument is primarily designed for community noise surveys.
Measurements from 30-130 dB (A) can be carried out with
this instrument. Noise measurements were taken following the
prescribed procedure stipulated in the manual of the
manufacturer of Sound Pressure Level meter. In order to
identify the magnitude of increased level of sound than the
ambient permissible sound level the percent increase was also
calculated and incorporated in the results. Table 3. Shows the

4. RESULTS AND DISCUSSION
The present study establishes that need of awareness regarding
adverse impact of noise amongst the public. During the
preliminary survey of noise level at different locations, all the
locations recorded the standard permissible limit values higher
than that of Standards. It was observed that in these locations
the noise level varies considerably due to the high volume of
traffic flow and commercial activities.
4.1. Silence Zone
None of the places in the silence zone recorded noise level
below the prescribed limit set by the CPCB (refer table 3).The
lowest values recorded was 42 dB (A) in government Higher
secondary school. The educational institutions are exposed to
very high noise levels, which might cause nuisance to the
students in addition to the adverse health effects. Government
girl’s higher secondary school is located at one of the busiest
roads in Chidambaram and is the highly affected one. The
railway station, railway track, marriage halls are also nearer to
the school.
Figure2. Average ambient noise levels in dB (A) during
September 2011(Sensitive areas)
The average Leq for the day is obtained as 64 d B (A).By
virtue of its location, the school is exposed to high noise
levels. The average noise level during September 2011,
October 2011 and November 2011 is shown in figures 2,3and4
respectively.
Figure 3.Average ambient noise levels in dB (A) during
October 2011(Sensitive areas)
Noise levels recorded in all the sites of silence zone exceeded
the prescribed standard level of 50 dB (A). All the places
selected under silence zone had noise level above the
permissible limit set by CPCB. The average noise level at
Pachaiyappa’s school ranged between 50.66 & 86.66 dB (A).
The noise level at Government hospital was recorded between
54.33 & 88.33 dB (A). The noise level at Government higher
school was recorded between 45.3 &51.63 dB (A). The noise
level at O.P.road (Medical College) was recorded
between54&82 dB (A).

4.2. Commercial Zone
All the places under commercial zone recorded fairly higher
noise level than the prescribed standard limit. The average
noise level at Bus stand ranged between 86and 101d B(A).The
average noise level at south car street ranged between 55
and 95d B(A) and it was between 62 and 88 d B(A) at west
car street. The average noise level during September 2011,
October 2011 and November 2011 is shown in figures 5,6 and
7 respectively.

Figure7. Average ambient noise levels in dB (A) during
November 2011(Commercial areas)
4.3. Residential Zones
The prescribed limit for the residential area is 55 d B (A)
during daytime and 45 d B (A) during nighttime. None of the
selected places of the residential zones in Chidambaram is
recorded less than 55 d B (A) during daytime. All the places
had values that ranged between 54.33 and 84.6 d B (A) at
sirkazhi main road, 58.6 and 82.6 d B (A) at Omakulam and
57and 75.6 d B (A) at Annamalai University campus The
average noise level during September 2011, October 2011,
and November 2011 is shown in figures 8, 9 and 10
respectively.
The various ambient noise parameter or noise indices, such as
L10, L50, L90, Leq, Lnp, TN and NC Were also computed. The
average noise level indices in silence zone during September
2011 to November 2011 are shown in figure 11. The average
noise level indices in commercial zone during September 2011
to November 2011 are shown in figure 12. The average noise
level indices in residential zone during September 2011 to
November 2011 are shown in figure 13.The average ambient
noise parameters are given in table 5.This table 5 shows the
data for noise level indices for all the selected zones of
Chidambaram town.

CONCLUSIONS
The honking of horns, flow of ill-maintained vehicles and
poor road conditions on roadsides that cause traffic congestion
were found to be the reasons for high noise level in
Chidambaram town. People in general, patients and students
in particular are highly exposed to noise level. Residential
areas are too exposed to the high noise level. The study also
concludes that:
1. Majority of the people are not wearing hearing
protective equipments Main reasons were their
negligence, feeling of un- comfortableness.
2. Almost all the people are highly exposed to high
noise levels [>60 dB (A)], without proper ear
protection.
Following measures need to be taken to tackle the situation:
a) . Ban on use of horns.
b) . Proper maintenance of roads
c) . Removal of road side encroachments
d) . Planting of recommended plant species
e) The implementation of the technical measures for
noise levels.
The following conclusions were obtained from our
study.Maxixmum noise level of 101d B (A) is observed at Bus
stand in the morning time and minimum noise level of 44d B
(A) is observed at government higher secondary school in the
afternoon.
The results of this study show that the level of noise pollution
in Chidambaram town far exceeds the acceptable limits set by
the CPCB.Even in the residential areas and vulnerable
institutions like schools and hospitals, noise is much higher
than the acceptable limit. This has serious implication on the
general health and wellbeing of the inhabitants of the
Chidambaram town. It is also observed that noise level is
closed related with the number of motor vehicles. Urgent
measures should be taken to control the level of noise
pollution in the town.
