Besides growing levels of air and water pollution, road traffic induced noise pollution has been recognized as potential threat to feasible quality of life especially in the urban areas. The accelerated pace of economic development urbanization, and increased vehicular mobility has affected remotest location of India and the Himalayan state of Uttarakhand is no exception to it. The serenity and tranquility for which it’s acknowledged globally, is growingly affected by traffic induced noise pollution caused by inflating Pilgrimage/tourism industry, rampant road constructions, encroachment, traffic mismanagement etc. The peak pilgrimage season brings with it uncontrolled traffic influx in the region. All the major pilgrimage towns located on the national Highway from Rishikesh to Badrinath are affected by the vehicular Noise pollution and traffic congestion especially during the holy pilgrimage season. The study tries to evaluate the Noise pollution problem in one of the important towns of Uttarakhand ‘Srinagar ’located 105 kms upstream from Rishikesh, on NH-58. Heavy movement of traffic and illegitimate usage of horns is considered main cause of noise pollution in the town which grows irrationally during the yatra season. The average number of vehicular flow was observed to be 890 vehicles/day during the yatra season (May) as compared to 575 vehicles/day during the non yatra season(January). The the average noise intensity levels of the town was recorded to be 70dB and noise levels have reached at an alarming stage. It was observed that in 4/5 noise monitoring location, the noise intensity was above the prescribed noisestandard level of Central Pollution Control Board (CPCB), and Bureau of Indian Standard (BIS). The vulnerability to various noise induced health hazards was also very high in the area because the valve of R was 0.78.

2013
The problem of road traffic noise pollution has become a concern for both the public and the policy makers. Noise level was assessed in 12 different squares of Rourkela city during different specified times (7-10 a.m., 11 a.m.-2 p.m., 3-6 p.m., 7-10 p.m., 10 p.m.-12 midnight and 4-6 a.m.). Noise descriptors such as L,eq, traffic noise index, noise pollution level, noise climate, Lday, Levening, Lnight and Lden were assessed to reveal the extent of noise pollution due to heavy traffic in this city. The equivalent noise levels of all the 12 squares were found to be much beyond the permissible limit (70dB during day time and 55dB during night time). Appallingly, even the minimum L eq and NPL values were more than 82 dB and 96 dB during day time and 69 dB and 91 dB during night time respectively. Lden values of investigated squares ranged from 83.4 to 86.1 dB and were even more than the day time permissible limit of traffic noise. The prediction model was used in the present study to pr...

Current World Environment
Noise pollution is a growing problem across the world and one which many people may not be aware of the impacts on their health. The environmental noise, and in particular the road traffic noise, remains a major environmental problem affecting the health and well-being of millions of people. With this background, a comprehensive ‘noise pollution assessment study’ was undertaken for a busy traffic corridor of Ahmedabad city of India. The traffic corridor which spans around 22.25 km passes through a mix of different areas like educational, commercials and residential. A two week long field survey was carried out on this corridor during 10-23 May, 2018 at 24 locations spread over the entire corridor. The assessment reveals that the average noise level always exceeded the prescribed guidelines of World Health Organization (WHO) for the daytime noise (75 dB (A) for Industrial area, 65 dB (A) for Commercial area, 55 dB (A) for Residential area and 50 dB (A) for Silence zones), which is qu...
Noise is one of the popular pollution due to the rise in the utilization of heavy duty motor vehicles, We make sounds practically every seconds of our day, but to the extend it has reached an unfavourable high intensity which had cause many disturbances and irritation to others emotionally that has adverse effects on our daily activities.
