A Review on Noise Pollution due to Traffic

[2] Wats and Godfry (1999) studied that there is considerable interest in the use of sound absorptive materials for reducing noise reflected from noise barriers although there is little reliable information on their effectiveness in practice. The primary object was to determine, under carefully controlled measurement conditions, the effects on roadside noise levels of applying sound absorptive materials to the traffic face of noise barriers. Measurement of traffic noise were made close to the roads both behind and opposite the barriers with the panels in the normal position and then measurements were repeated after the panels had been reversed such that the reflective side faced the traffic. It was found that at both sites there was an increase of noise of generally less than 1 dB when the barrier face was changed from sound absorptive to reflective.

Evaluation of Road Traffic Noise Pollution in Quetta (Pakistan)

Evaluation of Road Traffic Noise Pollution in Quetta (Pakistan)

Noise pollution is the consequence of urbanization and industrialization and is considered as major problem of urban areas. The most important factors raising noise pollution in urban areas include vehicular traffic, neighborhood electrical appliances, TV and music systems, public address systems, and railway and air traffic. Increase in noise level, across the world, has motivated the researchers of the world to this study the problem and its impact on the environment. Also, researchers have reported that the road traffic noise is the leading source of noise in urban areas [1]. Noise pollution is not only the growing problem of developing countries but also of the developed countries. According to researchers, over 130 million people in Europe suffer from exposure to noise levels above 65 dB(A) [2].

IoT Based Noise Pollution Reduction in Traffic Jams

IoT Based Noise Pollution Reduction in Traffic Jams

Due to the increasing population of vehicles on road, the noise pollution levels have risen beyond limits. No longer can a person travel from one place to another without being subjected to high intensity noise coming from vehicles. This noise can have varying effects on a person,such as hearing imparity, high blood pressure, stress etc. At traffic signals or traffic jams, people tend to horn relentlessly adding nothing but noise to the environment. This paper tries to solve this problem by proposing an IoT-Based solution. With the use of an ESP-8266 microchip and a sound sensor, the noise produced in the traffic can be reduced by cutting down on the unnecessary honking by drivers. Reduction in the levels of noise pollution helps to increase productivity, reduce stress etc.

Road Traffic Noise Pollution and its Management in Tanjong Malim, Perak

The increasing number of motorized vehicles in the roads especially in the populated area are the major contributor for noise pollution. This research aimed to study the problem of traffic noise in the town of Tanjong Malim, Perak Darul Ridzuan. For this purpose, a total of nine randomly selected research stations covering the main streets, business center, school and the populated areas were randomly selected. Measurement and observation of level of noise parameters have been using the equipment called Integrating Sound Level data logger Extech Instruments Model 407780. The observations made were at least ten minutes for every observation time for the morning (between 8.00 am-10.00 am), noon time (between 12.00 noon-2.00 pm), evening (between 5.00pm-7.00pm) and night (between 10:00 pm-12.00malam) which covers weekdays and the weekends. The results showed that all value at the all stations is exceeded the standards set by the Department of Environment Malaysia; the noise level 65 dBA for the daytime and 55 dBA for the night-time. Passage area in front of North Gate UPSI recorded the existing Leq 76.6 dBA the highest existing Leq values compared to other nine stations on weekdays observation. Weekend observations recorded value almost similar to the days of the highest noise level recorded in the same way in front of the main door UPSI (74.8 dBA). Various other factors also contribute to traffic noise in the town of Tanjong Malim, such as the proximity of a close to main roads, the higher number of heavy vehicles routing, the estate of vehicle engine and so on. Various mitigation measurement should be considered to negotiate this problem including the sound management aspect, awareness campaign through education, physical construction of natural fortress such as by planting trees between the noise provenance and receiver, efficient traffic management and by law enforcement.

COMMERCIAL AREAS OFALLAHABAD CITY AND ITS IMPACT ON CONTOUR TRAFFIC NOISE POLLUTION OF THE THE ENVIRONMENT

41 | P a g e roads [5]Generally, motor vehicles, which form a significant part of urban environment, are an important source of noise emission, contributing about 55% of the total urban noise [6]The rapid growth of vehicular population gives rise to unrestrained noise pollution and other associated health problems causing both short term as well as long term psychological and physiological disorders. Traffic can be considered as the major source of noise pollution in large cities [7,8]Depending on its duration and volume of exposure noise pollution effects can be categorized into physical effects (temporary and permanent loss of hearing), physiological effects (high blood pressure, cardiac problem) and psychological effects (sleeplessness, decrease in working efficiency, stress, annoyance etc) [9] Chronic exposure to noise can cause temporary as well as permanent loss of hearing. Besides the auditory effect noise can also cause other significant non auditory health effects, such as cardiovascular problems, hypertension, changes in social behavior and induces depressive tendencies [10] Long-lasting, high- level sounds are the most damaging to hearing and generally the most annoying. Therefore, a study was planned on noise generated from the different commercial areas of Allahabad city and its impact on the people so as to bring down the pollution level through public participation and to suggest mitigation measures.

A study on ambient and traffic noise pollution in Vijayawada, Andhra Pradesh, India

A study on ambient and traffic noise pollution in Vijayawada, Andhra Pradesh, India

Noise is unwanted sound that is harmful, annoying, causes disturbance and may adversely impact the work efficiency and hearing. Increased activities and needs in modern urban life are causing severe noise pollution. Noise pollution due to major source of pollution in urban areas. Fast growing vehicle population in urban regions in the recent years, has resulted in tremendous increase in traffic on roads causing alarming noise pollution, besides air pollution. Traffic noise is ctors like traffic volume, vehicle mix, pavement type and vehicle condition (Marathe, 2012). Noise level increases with traffic volume in an exponential manner and depends on several parameters such as source, medium, vehicle ce from source etc. (Vilas and Nagarale, 2013, Suhas and Adavi, 2015). Hence, the overall noise is dependent on the characteristics of the vehicle and the relative proportions of the vehicle types included in the flow. the “threshold of hearing” and the “threshold of pain”. In terms of pressure, this 20 kPa (Garg, 2014). Noise level is measured in terms of decibels (dB). The Noise levels are measured using a sound level meter and calculated values such as L10, L50, L90, are used to estimate equivalent value of sound level (Leq) while Traffic Noise Index (TNI), Noise Climate (NC), Noise

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

The noise originates from human activities, especially the urbanization and the development of transport and industry. Though, 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. 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 ameliorate the same. It is, along with other types of pollution has become a hazard to quality of life. Kiernan (1997) finds that even relatively low levels of noise affects human health adversely. It may cause hypertension, disrupt sleep and/or hinder cognitive development in children. The effects of excessive noise could be so severe that either there is a permanent loss of memory or a psychiatric disorder (Bond, 1996). Thus, there are many an adverse effects of excessive noise or sudden exposure to noise. In India, the problem of noise pollution is wide spread. Several studies report that noise level in metropolitan cities exceeds specified 60dB. Murli and Murthy (1983) also found that traffic noise in Vishakhapatnam exceeds 90dB even in morning hours that acts as a source of nuisance. The noise pollution is not a unique problem for developing countries like India only. In China, till third century B.C., instead of hanging men for dangerous crimes, noise was used for their torturing. The worrisome effects of noise are dangerous enough that noise problem is considered next to crime by certain countries (Kapoor

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

Abstract: Molecules vibration creates sound and it can pass through any substance whether it is a solid, liquid or gas but vacuum has no molecules, and that’s the reason, the sound cannot travel through. Noise pollution is displeasing human being, animal or machine created sound that disturbs the activity or balance of human and animal life. Due to increasing population and industrialization, the transportation in the city has increased to un-imaginary highs and causes want of efficient mass transfer system. The increased vehicular numbers on existing roads has considerably pushed traffic to create noise that adversely affects the human beings and living creatures. In the present study efforts were made to study the noise levels at different locations by using sound level meter so that the negative aspects of harsh sound can be mitigated. The collected data will be analysed to know the traffic behaviour and characteristics of different roads and location of the Gandhinagar city like hospitals, school, office's and residences etc. and then the maximum noise level will be estimated.

ROAD TRAFFIC AS A SOURCE OF NOISE POLLUTION (CASE STUDY: TRSTENIK MUNICIPALITY)

Further research should inspect deeper connections between noise and health problems of the population. In the meantime, in order to improve managing noise levels, it is necessary to: identify the so-called black, gray and white acoustic zones; carry out a sharper control of redirecting heavy vehicles to the roads around the city, increase control of the noise emitted by motor vehicles during the technical inspection and daily traffic; continue with extending the network of streets with automatic traffic regulation and synchronization of traffic lights in certain directions; introduce time pieces on traffic lights that last more than 1 minute, especially at intersections with magistral significance; plan the installation of green and protective belts and arrange multi-storey plantations of various woody along traffic roads in order to reduce the level of municipal noise.

Noise Mapping In Mumbai City, India.

Noise Mapping In Mumbai City, India.

Noise levels at different places were recorded using basic Sound Level Meter (Model no. SL-4010) on 15 th March2012 . The route followed was from Churchgate, Mumbai, India upto Andheri, Mumbai India. A road parallel to the western railway line was studied(Table 1.1). This was maintained to avoid any interferences of rail noise. When the instrument was switched on, a range was selected which was ideal for the surrounding. (The instrument has 3 ranges 35-80dBs, 50-100dBs and 80-130dBs). After the selection of the range the microphone was pointed or faced towards the traffic, which was the noise source. Since the instrument showed fluctuating values depending on the changing noise levels, a method was devised to maintain uniformity. Readings were recorded after every 10 secs. After 10 secs whatever value was displayed on the SLM screen was noted down. Three such readings were noted to calculate the average value. The data was further used to calculate Leq (Eq.1), Noise climate (NC) (Eq. 2) and Noise pollution level (Eq. 3) (Ehrampoush M., 2011). A city noise map was prepared. This Data was used for making Isopleth maps. Different symbols were used to indicate the different range of noise pollution levels and a noise map is constructed (Fig. 1.0).

Analysis Of Motorized Vehicle Sound Pollutionin Front Of Mall Yogya Plaza Bogor

Analysis Of Motorized Vehicle Sound Pollutionin Front Of Mall Yogya Plaza Bogor

The level of noise pollution in a road section is usually reflected 10% (18 hours) meaning that the average material noise level in the place is exceeded by 10% in an interval of 18 hours (6:00 to 24:00 BBWI). Noise is measured by carrying out local measurements on the side of the road in normal traffic conditions with a dBA measurement unit. Noise pollution due to traffic ranges from 60 - 80 dBA. Control of noise due to traffic on the environment can be done in two ways, namely at the source and by diffraction. Noise can occur due to communication, hearing loss and the influence of health and behavior. Sometimes loud noise is mixed with other sounds that reach the ear and will be recorded by the brain, so that those who receive noise will permanently lose hearing [8]. The sound generated by the mode of transportation is always unpopular, because it disrupts the community and activities around it. Even in certain cases can cause people to have an accident. The sound of vehicles passing through a single point is very uncomfortable (such as trains that will pass at a flat crossing and vehicles that will enter an intersection). This sound causes more noise and can be used as a warning to other vehicles. The effects of noise pollution and some examples of noise levels are summarized in the table below [13], [14],[15], [21].

and loud neighbours and that from other urban sources due to lack of theoretical reason. On the other hand, insufficient evidence is the main reason for national noise regulation to put more attention towards airport, construction, traffic and work-related exposure to noise (Hammer et al., 2014; Nelson et al., 2005). Instead of surveillance under environment health authorities, enforcement of neighbour noise law, where they exist, normally falls within the purview of local nuisance laws. The enforcement is also mostly left to local governments with varying degree of effectiveness as well as the prioritization. (Hammer et al., 2014). Nevertheless, there are good theoretical reasons to claim that neighbour noise could be an additional effect to health through channels which are not captured in studies of traffic and airports. There are three ways that distinguish loud neighbours from street noise that it is less predictable and often occur with higher informational content, even if the decibel level is similar or even lower (Niemann et al., 2006).

THE LEGAL IMPERATIVES FOR REGULATING NOISE POLLUTION IN NIGERIA IN THE QUEST FOR SUSTAINABLE DEVELOPMENT: LESSONS FROM INDIA

THE LEGAL IMPERATIVES FOR REGULATING NOISE POLLUTION IN NIGERIA IN THE QUEST FOR SUSTAINABLE DEVELOPMENT: LESSONS FROM INDIA

This paper examined the correlation between noise pollution and SD and the effect of noise pollution in the attainment of SD. It also reviewed the regulations for the management of noise pollution in Nigeria and compared same with the position in India. While noting that average peak time noise level in most major cities in Nigeria is higher than the permissible limits, the paper finds that noise has the potential to adversely affect the quality of life of persons and the attainment of SD. It also found that like India, our laws and regulations need review and harmonization. However, the paper noted that the government should encourage research and development to acquire data bank to be used in policies and laws. The Indian judiciary unlike Nigeria’s is equally disposed to a liberal interpretation of the right to a healthy environment as essential ingredient of the right to life. Clearly, because laws can change behaviours in ways that benefit society as a whole, the paper concludes that effective management of noise pollution in Nigeria using legal imperatives is indispensable to the attainment of good standard of living and SD in Nigeria. It therefore, made some salient recommendations to that effect.

The evaluation of Noise Pollution at Samen district in Mashhad by means of Geographic Information System (GIS)

The evaluation of Noise Pollution at Samen district in Mashhad by means of Geographic Information System (GIS)

Mashhad, with a population of over five million people due to its religious, economic, and industrial structure is considered the second biggest and most populated city after Tehran in Iran. Because of the existence of the shrine of Imam Reza (peace be upon him), Mashhad annually welcomes over 32 million pilgrims from inside and outside the country. Cars and transportation vehicles are the most important sources of noise pollution in Mashhad that also affect other areas nearby and since the question of noise pollution in Mashhad particularly in the district of Samen has been neglected, compared to other forms of pollution. Despite studies conducted in high traffic areas of Tehran [8] and other large cities in the field of noise pollution, until now, no comprehensive study has been conducted in this area, therefore the survey of this question in this district is necessary.
