Assessment of noise level in Burdwan town, West Bengal

Abstract: Cities and towns of the world are now facing enormous rise of noise pollution problem due to very high population rise, transport congestion and associated commercial and industrial activities. Burdwan, a district headquarter (100 km away from Kolkata) is one such town where noise pollution is very frequent. In order to assess noise level, noise data were collected from various places of the town by sound level meter with a duration of 30 minutes/location during specified time like 6.00 am, 10.00 am, 1.00 pm, 4.00 pm and 6.00 pm. Most of the monitoring places either belongs to silence category or commercial category areas. From the tabulated data, it was found that sound level lies within the range of 64-85 dB or above in different time at different places. The locations that belong to the silence zone have the noise level up to 90 dB. Statistically noise level in all these zones differ significantly at their peak hours. Noise pollution adversely affects our environment as well as human beings. Sound causes both pathological and psychological disorders in human beings. Implementation of rules and regulations under section 20, 21J, 41, 68(I), 70, 90, 111A of Environment Protection Act, 1986 and of course various technological methods and public awareness are very essential to check noise pollution in Burdwan town.

Effects of COVID-19 pandemic on festival celebrations and noise pollution levels

Abstract: India is a country where every religion and community celebrates their culture Festivals have an important role in Indian culture and are celebrated whole-heartedly by the citizens Most of these celebrations culminate to causing pollution especially noise pollution due to festivities and rituals One such festival is Ganesh Chaturthi or Ganeshotsav which is magnificently celebrated in Maharashtra state of India In the present study, noise pollution levels during Ganeshotsav at famous community pandals in Mumbai city were monitored in the year 2020 Noise level data was analyzed based on indices such as L-10, L-50, L-90, noise pollution level (L-NP) and noise climate (NC) Comparison of noise levels was carried out for the collected data during Ganesh Chaturthi in the previous years of 2018 and 2019 The city witnessed simple festival celebration in eco-friendly manner leading to significant decrease in noise levels due to CoVID-19 pandemic The pandemic situation is an eye-opener for the city administration with demonstration in reduction of noise pollution Many aspects of the pandemic can be carried forward in making new guidelines and policies to curtail pollution and eco-friendly celebration of festivals

Life cycle sustainability assessment of window renovations in schools against noise pollution in tropical climates

Abstract: Because of the significant increase in the number of noise complaints, reducing and limiting noise pollution have become prevalent subjects related to the retrofitting of school buildings. The present case study considers a multi-apartment school building in the city of Johor, Malaysia. The life cycle criteria evaluated in this study are carbon dioxide (CO2) emissions and the cost and social impacts of each window type. The preliminary assessment showed that the school's current noise level is 74.31 dB (A), which exceeds the acceptable threshold of 55 dB (A). In the next step, three more windows were applied and reevaluated, with the triple glazing window performing the best (48.66 dB (A)), followed by the double glazing window (51.3 dB (A)). In terms of carbon emissions and cost, the preference window had the best performance. Meanwhile, considering the social aspect, the double glazing window performed the best. Because three different windows were deemed the best choice depending on which of the four criteria was considered, multi-criteria decision making (MCDM) was applied by TOPSIS to weigh and estimate each alternative. The final decision was made by giving priority to the four criteria as follows: noise (0.322), cost (0.257), CO2 emissions (0.227), and SLCA (0.194). The MCDM process revealed that the double glazing window is the most sustainable choice for school buildings. Furthermore, two sensitivity analyses were performed to eliminate human subjectivity involved in AHP.

Acute cardiovascular health effects in a panel study of personal exposure to traffic-related air pollutants and noise in Toronto, Canada.

Abstract: Urban populations are often simultaneously exposed to air pollution and environmental noise, which are independently associated with cardiovascular disease. Few studies have examined acute physiologic responses to both air and noise pollution using personal exposure measures. We conducted a repeated measures panel study of air pollution and noise in 46 non-smoking adults in Toronto, Canada. Data were analyzed using linear mixed-effects models and weighted cumulative exposure modeling of recent exposure. We examined acute changes in cardiovascular health effects of personal (ultrafine particles, black carbon) and regional (PM2.5, NO2, O3, Ox) measurements of air pollution and the role of personal noise exposure as a confounder of these associations. We observed adverse changes in subclinical cardiovascular outcomes in response to both air pollution and noise, including changes in endothelial function and heart rate variability (HRV). Our findings show that personal noise exposures can confound associations for air pollutants, particularly with HRV, and that impacts of air pollution and noise on HRV occur soon after exposure. Thus, both noise and air pollution have a measurable impact on cardiovascular physiology. Noise should be considered alongside air pollution in future studies to elucidate the combined impacts of these exposures in urban environments.

Noise and air pollution of high-speed rail systems

Abstract: Transportation noise and air pollution problems are a nemesis to our modern society. Each transportation system, highspeed rail HSR included, has its own noise spectra, characteristic air pollutant...
