“…The noise barrier designed for Delhi Metro Rail Corporation (DMRC), New Delhi, India consisting of half Y shaped structure that includes a 2 mm thick aluminium alloy as the back plate, 1 mm thick aluminium alloy sheet (30% open) as facing surface, 50 mm thick glasswool of density 40 kg/m 3 wrapped in tissue bags and polythene cover, and the whole assembly fixed in a GI framework serves as an illustration of specific source noise mitigation (Mohanan et al, 2001). The use of the TOPSIS approach can thus be very helpful for the town planners and development authorities for selecting the best practicable option, considering all the pros and cons, as the long term stability of the barrier and compatibility with the local environment are equally important as the acoustical considerations are, especially for the road traffic noise abatement and control (Garg et al, 2015a;2015b). …”

The paper presents a retrospective study for selection of noise barrier for road traffic noise abatement. The work proposes the application of Fuzzy TOPSIS (Technique for order preference by similarity to an ideal solution) approach is selection of optimal road traffic noise barrier. The present work utilizes the fuzzy TOPSIS model proposed by Mahdavi et al. (2008) in determination of ranking order of various types of noise barriers with respect to the various criteria considered. It is suggested that application of this approach can be very helpful in selection and application of optimal noise barrier for road traffic noise abatement.

“…Table 1 shows the proposed ambient noise standards 13 . The modified adjustments to ISO 1996ISO -1:2003) recommendations are to be added to the measured or predicted L Aeq,24h depending upon the type of sound source and the character of sound as explicitly mentioned in Garg et al 13 . The detailed explanation and basis for selecting a cumulative noise exposure metrics such as L Aeq,24h and modified adjustments proposed can be found in Garg et al 13 .…”

“…The Panel for Acoustics, Sound Insulation and Noise Control, CED 46:P20, constituted by the Bureau of Indian Standards is responsible for amendments and revisions in National Building Codes of India 12 . Although the proposed revisions in the ambient noise standards and sound regulation requirements have been explicitly discussed earlier 13,14 , the objective of the present study is to consider the overall noise pollution control policies, ordinances and measures for all types of noise sources in totality in the Indian scenario and suggesting a road map for developing a 'noise-free community' in Indian cities in the next decades.…”

We describe the diversified National Ambient Noise Monitoring Network (NANMN) set up across 7 major cities of India and covering 70 stations for continuous noise monitoring throughout the year. The annual average L day (06-22 h) and L night (22-06 h) values observed in 2015 for these 70 locations are described. Of these, 25 locations are in commercial zones, 12 in industrial, 16 in residential and 17 in silence zones. Each city has 10 noise monitoring stations installed for analysing environmental noise pollution levels round the clock (24  365 h). The long-term noise monitoring shows that ambient noise levels are very high compared to the recommended standards for some sites and thus noise abatement measures are essentially required for controlling these levels. The present study is focused on evaluation, analysis and reporting of environmental noise pollution in seven major cities of India and is instrumental in planning for the noise abatement measures for controlling noise pollution in these cities. Such a noise monitoring network established in India is unique and one of the largest noise monitoring networks of its kind across the globe. Keywords: Day equivalent level, day-night average sound level, National Ambient Noise Monitoring Network, night equivalent level.NOISE pollution has become a serious concern over the past several years in India. With growing vehicular population and urbanization, it is imperative to monitor the ambient noise levels and devise suitable measures for control to avoid health hazards and annoyance faced by the community. The evidence for effects of environmental noise on health is strongest for annoyance, sleep and cognitive performance in adults and children. The occupational noise exposure also shows some association with high blood pressure 1 . There have been many such studies conducted so far on the noise exposure and correlation with human blood pressure 2-5 . Meta-analyses have been carried out to derive the exposure-response relationships that can be used for quantitative health impact assessments 6 . The meta analysis of 24 cross-sectional studies on the relationship between road traffic noise and prevalence of hypertension reported an odds ratio (OR) of 1.07 (95% confidence interval (CI) = 1.02-1.12, P < 0.05) per 10 dB increase of 16 h day-time average road traffic noise level (L Aeq,16 h ) in the range of <50 to >75 dB (refs 7, 8). In India, there have been limited studies carried out on correlating the effect of noise on human health. A recent study provides evidence that road traffic noise is a serious cause of concern 9 . The study infers that association between transportation noise exposure and cardiovascular disease is evident, but not at significant level. A similar study suggests epidemiological evidence that exposure to road traffic noise of
