Genesis of Road Traffic Noise on Human Health

Urbanization, monetary development and mechanized transport are a portion of the main thrusts for natural pollution presentation and wellbeing impacts. Noise pollution is a disappointing human, creature or machine-made sound that aggravates the action or adjust of human and creature life. Vadodara is the third biggest city of Gujarat after Surat and Ahmadabad having assessed populace of 18 lakhs. Because of increment populace and industrialization, the transportation in the city expanded to unimaginable statures. The expanded vehicular numbers on existing roads has significantly pushed activity to make pollution that antagonistically influences the individual and living animals. In India, the Pollution (Regulation and Control) Rules, 2000 have been encompassed under the Environment (Protection) Act, 1986. These are a course of action of tenets for direction and control of pollution. In 1999, WHO outlined the logical proof on the unsafe effects of pollution on wellbeing and made proposals on rule esteems to secure general wellbeing in its Guidelines for group noise. Constant introduction of human body with abnormal state of group noise may prompt anxious, hormonal, and vascular move that have sweeping outcomes (Singh and Davar 2004). Thinks about showing a causal pathway that straightforwardly interface noise (at biological levels) and irritated lay down with cardiovascular infection and additionally other long-haul wellbeing results are as yet missing (Hume, Mark Brink, Mathias Basner 2012). Bothered rest has additionally been related with expanded recurrence of savage goes about and in addition abusive behavior at home, work and vehicle accidents, expanded work non-attendance (Cappuccio 2010). The watched relationship between poor rest and corpulence, diabetes, despondency, forceful and reprobate practices concern youngsters and teenagers, as well (Chen X 2008). Ecological pollution, especially that caused by transportation implies, is a developing issue in our cutting edge urban areas. It is viewed as a noteworthy reason for exogenous rest aggravations, after physical professional blames and day strains (Basner M 2011).

Noise is unacceptable level of sound that creates annoyance, hampers mental and physical peace, and may induce severe damage to the health. Transportation operations are major contribution to in the modern urban environment; traffic noise is generated by the engine and exhaust systems of vehicle, by aerodynamics friction and by the interaction between vehicles and its support system rail interactions). traffic noise, thus, is a very important element in environmental impact studies, since car is one of the most used transportation mean in developing t is one of the harmful agents for citizenships; therefore many countries have n limits for vehicles and s to reduce road traffic noise E1, 9, 13, showing an alarming rise and it exceeds the prescribed levels in most of the urban cities of developing countries like Nigeria and Akure in particular. Noise in big cities is considered by the World Health Organization (WHO) to be the third most hazardous type of pollution, right after air and Investigation in several countries shown that noise has adverse effect on human health, living in close proximity to

Scenario of Traffic Noise Pollution and its impact on human health: An Empirical Case Study of Kolkata City

Scenario of Traffic Noise Pollution and its impact on human health: An Empirical Case Study of Kolkata City

The discussion has been surveyed in the various traffic intersection points in the city of Kolkata under the jurisdiction of Kolkata Municipal Corporation which is located at 22 0 30'N to 22 0 40'N latitude and 88 0 15'E to 88 0 20'E longitude and has an area of 187.33 km 2 .After the implementation of auto de-licensing policy most of the people from Kolkata wish to purchase their own personalised branded car, as a result huge congestion could be occurred followed by extreme level of traffic congestion could be observed at the busiest traffic intersection points in the city. According to the data obtained from West Bengal Pollution Control Board, ambient noise measurements have been taken by WBPCB and CPCB at 27 locations across residential, commercial, industrial and silence zones in the city of Kolkata from 1993 onwards. Road traffic noise pollution is also alarming and above the permissible standards in the city in today’s context. However vehicular noise pollution is the predominant cause of noise pollution in the Kolkata city. To understand the situation of noise pollution, eight intersection points of the city have been selected. In northern part of Kolkata four traffic nodeshave been selected because these are busiest traffic sites there followed by in southern Kolkata another four busiest traffic pointshave been selected as monitoring sites. Using the Noise Meter noise data record has been collected during peak and lean hours of a day. The selected survey sites are Ultadanga, B.B.D Bag, Shyambazar, Maniktala from north Kolkata whereas Sealdah, Jadavpur, Gariahat and Rashbehari nodes have selected from south Kolkata as survey sites.

Evaluation of Road Traffic Noise Pollution in Quetta (Pakistan)

Evaluation of Road Traffic Noise Pollution in Quetta (Pakistan)

background noise level is 50 dB (A), noise can also cause annoyance and can decrease work performance [6]. According to the World Health Organization, noise pollution is nowadays the third most hazardous environmental type of pollution, preceded only by air and water pollution [7]. Noise pollution has notable adverse impacts on the health of human beings. There is an increasing probability to heart disease among the peoples who are constantly living in the areas where the out door noise level is greater than 65-70 dB[8]. Another survey reveals the fact that traffic noise is not only the main cause of headache, high BP, dizziness and fatigue at working place but is also badly interfering in daily life activities such as resting, reading, and communications [9]. A study among the workers exposed to road traffic noise disclosed a deep relationship between the exposure of traffic noise and the noise-induced hearing loss (NIHL)[10].

Evaluation and Analysis of Road Traffic Noise on a National Highway

Evaluation and Analysis of Road Traffic Noise on a National Highway

Noise is a common environmental pollutant in nearly all urban communities. Noise can be emitted from various sources such as aircraft, road traffic, railways, construction, factories, etc. Among these, road traffic is a major source of noise in the urban areas contributing to 55% of the total noise. Social surveys conducted in various cities throughout the world indicated that traffic noise is the major source of nuisance and annoyance [1,2].Social survey conducted in various cities throughout the world indicated that traffic noise is the main source of nuisance and annoyance [3,4].The effect of noise depends on various factors such as time duration, noise sound level, distance from the source, etc. The health impact associate with the noise pollution on human well-being is done by various researchers [5, 6, 7, 8]. The CBCB of India in its notification for noise has laid down the ambient noise standards [9]. FHWA model was found to be suitable for the prediction of noise in India within a fair degree of accuracy.

Environmental noise exposure, early biological risk and mental health in nine to ten year old children: a cross-sectional field study

Environmental noise exposure, early biological risk and mental health in nine to ten year old children: a cross-sectional field study

In comparison with Stansfeld et al. [12] we found similar main effects of aircraft and road traffic noise on mental health after adjustment for early biological risk; hyperactivity increased with aircraft noise and conduct problems decreased with road traffic noise. The excep- tion was that after the addition of early biological risk, hyperactivity became borderline significant, rather than significantly related to aircraft noise at school. This is likely due to lower power in the current analyses because of the smaller sample used due to missing data with the inclusion of the early biological risk variable. It is thought that noise affects hyperactivity through arou- sal. According to the arousal theory, noise exposure changes arousal level, which may lead to raised physio- logical activity levels which might become manifest as psychological difficulties [10]. Such mechanisms are also generally conceptualized as fitting the stress-diathesis model, in which noise exposure increases arousal, and chronic exposure leads to chronic physiological changes and subsequent health effects. However, the finding of reduced conduct problems with increased road traffic noise was unexpected and is not consistent with this theory. Stansfeld et al. [12] suggest that this finding may be due to chance, or due to the difficulties in accurately measuring road traffic noise.

Benefit measures for noise abatement: calculations for road and rail traffic noise

Benefit measures for noise abatement: calculations for road and rail traffic noise

Monetary values act as this common metric and in this paper we estimate monetary values for road- and rail-traffic noise abatement. These two noise sources are of differ- ent character and it is well established that the annoyance from noise individuals report differs between the two modes of transport [41]. The origin of this paper was a recent revision of the official monetary benefit measures of noise abatement, from now on the “ASEK values”, 1 carried out in Sweden [65]. The original values were revised to take into account general price increases and an increase in real growth. It was also decided that the original values should be adjusted upwards since it was assumed they they did not reflect the total social cost, but were missing the social cost of health effects from noise exposure [65]. This revision drew to the attention the potential need for a more com- prehensive revision due to the fact that the values for all transport modes were based (after also other sources had been taken into consideration) on estimates from a study in which the effect on property prices from road noise was examined [63, 71].

Street-level noise in an urban setting: assessment and contribution to personal exposure

Street-level noise in an urban setting: assessment and contribution to personal exposure

Perhaps the most important contributor to the urban soundscape is street-level sound. Given the ubiquitous exposure to street-level sounds among urban dwellers, and the potential for annoyance and health effects from this noise, strict urban noise control measures for street- level sources of noise are increasingly being imple- mented. However, even in cities such as New York City (NYC), which has rigorous regulations on, and enforce- ment of, nuisance noise sources (e.g., loud radios and car alarms) and construction–related noise, there is little focus on street-level noise (e.g., noise from roadway traf- fic, commercial activities, etc.,), though some studies have evaluated noise from mass transit in NYC [19,20]. The extent and magnitude of levels of street noise and air pollutants in NYC has recently been assessed [21], but the methodology used did not measure personal ex- posures, but rather levels at 10 ft above street level, well above the elevation of the heads of pedestrians. Variation in street-level noise with regards to vehicle traffic and road proximity has been explored, [18] but most studies on traffic noise have relied on modeling of noise levels from a network of roads, land use regression, or extrapo- lation of models based on a small number of noise sam- ples [22-24]. While these are cost-effective approaches to estimate traffic noise levels, they can neglect factors in the urban built and natural environment that may mitigate or exacerbate exposure to street noise levels, in- cluding temporal changes in noise, built environment factors, and vulnerable areas and individuals. These other factors have particular relevance for understanding exposure to street-level noise in the urban environment.

High Road Traffic Noise in Residential Buildings, High Annoyance and Self perceived Health Problems in a Sample from Santiago, Chile

High Road Traffic Noise in Residential Buildings, High Annoyance and Self perceived Health Problems in a Sample from Santiago, Chile

Five-point scale responses about road traffic noise annoyance and self-perceived health were dichotomized, grouping the lowest three categories and the highest two. Thus, the analyzed response variables correspond to indicators of high annoyance from road traffic noise, bad overall health state, high difficulty with concentrating, high degree of problems with sleeping, high degree of problems due to not feeling rested, presence of head or neck ache, and feelings of depression, anguish or neurosis. Only these response variables were selected from all items of the questionnaire, because they were theoretically and more plausibly related to environmental noise.

The transport sector as a source of air pollution

The transport sector as a source of air pollution

In the final decade of the century, the European and North American air pollution agenda has come back full circle and the issue of urban air quality that had last been at the top of the European agenda in the late 1950s rose again to the fore world wide. Diesel engines rather rapidly ceased to be cited as the environmentally friendly option as epidemiologists (Pope et al. 1992; Dockery et al. 1992), laboratory-based scientists (Diaz-Sanchez, 1997) and expert groups (Quality of Urban Air Group, 1993) found evidence that the particles emitted might be responsible for measurable increases in the manifestations of cardiovascular and respiratory disease even at the comparatively low levels of air pollution in modern Western cities. These had not been seen before because older statistical methods were not powerful enough to detect the very low signal-to-noise ratio of the effect of air pollution against other causes of health inequality and variability, and because computers to handle the large amounts of data required were not widely available. A large number of epidemiological studies followed on the effect of various road traffic emissions on a range of health end-points. Public concern over air quality is enhanced by its effects on children (Brunekreef et al. 1997) and has focussed in lay minds on associations with asthma, the incidence and prevalence of which have increased dramatically during the second half of the 20 th century (Holgate et al. 1995), Jarvis and Burney (1998)) in many countries (Miyamoto, 1997), (Ninan and Russell, 1992)). Current evidence suggests that air pollution exacerbates or provokes symptoms in those with pre-existing asthma (Krishna and Chauhan, 1996) but there is no good evidence that asthma is caused by air pollution (Holgate et al. 1995). There are also fears of cancer, as specific

Study The Impact Of Traffic Noise On The Health Of Road Side Shop Owners And Traders In Kolhapur City

Kiernan finds that an even relatively low level of noise affects human health adversely. Sharp and Donovan (1979) confirm that more people are exposed to noise from motor vehicles than any other single source of noise, they are also stated that more people are exposed to noise from motor vehicles than any other single source of noise. Pal and Bhattacharya (2012) done their case study in Agartala and it is pointed out that the most prevalent problems from the traffic noise include irritation, headache, tinnitus, and sleeplessness. The problem of noise pollution is less in small towns and villages. But, those residing in villages or towns along the national or state highways or close to railway tracks do bear the burnt of excessive noise (Salave 2014). Dasarathy and Thandavamoorthy (2013) concluded that the effects of excessive noise could be so severe that either there is a permanent loss of memory or a psychiatric disorder. According to (Savale 2014), The social survey should be one way of finding out what type of sound upset people most and they appear at present to be the only method of determine the effects of noise pollution.

Efficient Road Traffic Noise Model for Generating Noise Levels in Indian Scenario

Efficient Road Traffic Noise Model for Generating Noise Levels in Indian Scenario

Noise pollution is excessive, displeasing human, animal or machine-created environmental noise that disrupts the activity or balance of human or animal life. Various problems associated with noise include hearing loss, stress, sleep loss, distraction, lost productivity, masking speeches and a general reduction in the quality of life and opportunities for Tranquillity [6][5]. In addition, there are various studies carried out on road traffic noise pollution, which results in severe health problems such as, physical and psychological, irritation, human performance and actions [2][08], hypertension, heart problems, tiredness, headache and sore throat respectively [09]. India been a developing country is under a constant threat of it.. Migration of people, expanding cities, development of infrastructure, population explosion and urbanization are the factors which played a key role in motorization and thus, increasing the levels of various pollution.

Road traffic noise and hypertension: results from a cross-sectional public health survey in southern Sweden

Road traffic noise and hypertension: results from a cross-sectional public health survey in southern Sweden

The overall association between hypertension and road traffic noise is within the span of other recent findings. (Table 4) However, there are some notable differences. The prevalence of hypertension increases dramatically with age and a common relative effect model for the entire target population (18 - 80 years old in our study), regard- less whether the (self-reported) prevalence is e.g. 4% or 40%, does therefore not seem plausible. Surprisingly few studies have used separate effect models for different age groups. Our finding, with an exposure effect limited to rel- atively young and middle-aged, is fairly consistent with the recent study from the Netherlands, although the grouping of age differs between the two studies[15] A Swedish report found that the effect of road traffic noise on hypertension was stronger among study subjects that had lived in the same residence for more than 10 years[16] However, this study only adjusted for age and not for effect modification by age and the result is there- fore hard to interpret. No effect modification by years in residence per se was detectable in our study, which could be explained by the fact that most subjects had lived in their current residence for several years, thereby limiting the misclassification of long-term exposure.

Road traffic noise and registry based use of sleep medication

Road traffic noise and registry based use of sleep medication

examine health effects from environmental exposures. In- formation bias was prevented by using modeled noise ex- posure levels and registry data on sleep medications obtained independently both of each other, and other questionnaire data. The noise exposure was thoroughly assessed, using a detailed noise model. Furthermore, the study population included participants from both urban and suburban areas of the City of Oslo. This resulted in a broad range of noise exposure levels, which strengthened the possibility to detect associa- tions. A common approach in studies on noise and health is to use a cut off level for the noise exposure in order to account for background noise. In the present study, we found it appropriate to use the full range of exposure levels in the analyses. Firstly, be- cause the only noise source included in the noise model is road traffic noise. Thus, by increasing the lowest modeled noise levels to a level of background noise, misclassification of exposure would likely occur, the mean exposure level in the study population would increase, and the association between road traffic noise and sleep medication use could poten- tially be overestimated. Furthermore, a cut off would also mean that some of the variance in the exposure is lost and the accuracy of the analytic model will consequently be reduced.

Quantification of the exposure and effects of road traffic noise in a dense Asian city: a comparison with western cities

Quantification of the exposure and effects of road traffic noise in a dense Asian city: a comparison with western cities

noise of 60–64 dB, and a much lower proportion to the lower levels (<55 dB). We have explained this as a conse- quence of the high-rise built form of Hong Kong where there is both high population and high traffic density. The exposure-annoyance response relationship for road traffic noise in Hong Kong falls well within the tolerance limits of the Miedema and Oudshoorn [18] synthesized exposure- annoyance curve for the percentage of the population highly annoyed with road traffic noise. Fit within a toler- ance interval, rather than a confidence interval, is appropri- ate in comparing the exposure-response relationship from a single new study with the results of a prior synthesis of exposure-response relationships. The percentages of the Hong Kong population who reported they were highly sleep disturbed by road traffic noise also closely follows the exposure-response relationship for high self-reported sleep disturbance based on the pooled data used by Miedema and Vos [26]. There has been a Western bias, and a temperate-climate bias, in the studies used in prior meta- analyses of human responses to road traffic noise. How- ever, the exposure-response relationships for annoyance and self-reported sleep disturbance reported from the high-density, high-rise, sub-tropical city of Hong Kong are not inconsistent with these. This is an important finding for future urban planning and traffic noise management of many of the projected mega-cities in the world that will be located in non-temperate climatic zones in Asia and else- where and whose urban forms can be expected to reflect that of Hong Kong more than of cities in the west.

Analysis Of Road Traffic Noise At Express Highway

Analysis Of Road Traffic Noise At Express Highway

In world health organization (WHO) statements, “large city noise is considered to be the third most hazardous pollution”. Researches study noise problems in cities and try to find solution for these problems. At the time air pollution in incurs a large bill to pay when it comes to stop the escalation of global warming, urban noise pollution is in fact another complex issue for which academic community does not see possible short term plans to save the situation. It is only long term strategic planning that might realize some recovery to the current increasing levels of noise. However, transportation works is seen to a expanded and accelerated in the term of amount and variety, it is impractical to hinder traffic in main arterial for decrease traffic flow but it might be possible to detour traffic or to construct new roads, or other forms of end–of-pipe solutions. Noise will be a larger and serious social problem in the future if effective precautions are not taken accordingly.

Road traffic noise and children’s inattention

Road traffic noise and children’s inattention

Second, long-term impaired sleep causes neuronal loss, impaired brain development and failure to ad- equately develop coping skills [32, 33], making a longer noise exposure window relevant. In addition, noise ex- posure and annoyance may cause stress, and it is known that long-term stress in children is associated with sev- eral negative health effects, such as impaired brain development and impaired immune system functioning [34, 35]. Among the few studies that have looked at resi- dential noise exposure and inattention, associations have been found with both short-term and long-term noise exposure windows [8, 12]. However, we have only found one study that have investigated whether sleep is a medi- ating factor in this association: Stansfeld et al. [36] found no mediation by sleep in the association between ex- posure to aircraft noise and cognitive performance in 9 – 11 year-old children.

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

Transportation sector is one of the main contributors to noise in the urban areas. The traffic noise environment in Balasore, a city of Orissa, India in terms of standard noise offensives, community response and community health effects are worked out in the present study. A preliminary survey adopting questionnaire method amongst 212 local inhabitants also carried out to gather secondary information about the suffering of noise related physical condition problems. Noise pollution is not properly recognized despite the fact that it is steadily growing in Developing countries like India and in particular in the state Orissa. It is well conventional now that noise is a potential hazard to health, communication and pleasure of social life. Transportation sector is one of the main contributors to noise in this urban area. The present study explicitly reveals that the noise levels are greater than the permissible limit in all the six locations including 24 sites.

Modelling Of Road Traffic Noise

Modelling Of Road Traffic Noise

Vehicular noise is one of the most prevalent forms of pollution. Traffic noise annoyance has become a major issue with the advent of fossil fuels and development in vehicle technology. Vehicular noise is dramatically increasing with the increased number of vehicle population, especially due to speeding vehicles. Amongst all the sources of noise pollution, vehicular noise has been identified as the most annoying and health impairing one. Therefore, it had become important to check the traffic noise and enhance the environmental condition along the transportation corridor. This study attempts the development of road traffic noise model for Indian condition. A statistical regression model for predicting road traffic noise is developed based on A-weighted equivalent noise levels.
