Monitoring and modelling of noise pollution in commercial and industrial areas of Prayagraj Allahabad

Abstract

Noise pollution is recognized as a major cause of deteriorating quality of life in urban newlinearea because of rapid growth and development in terms of industrialization, urbanization and newlinecommercialization. The trend towards the use of more automated equipment s, high wattage newlinestereo, large construction machinery, increasing number of vehicles, trains and aircrafts and newlineother communication and transport systems has created a gradual acceptance of noise as newlinenatural by-product of the developments. In developing countries like India, noise is becoming newlinean increasingly omnipresent, yet unnoticed form of pollution even in developed countries. newlineAutomobile revolution in urban centres has proved to be a big source of noise pollution. newlineIncreasing traffic has given rise to traffic jams in congested areas of towns/ cities where the newlinerepeated hooting of horns by impatient drivers pierces the ears of all road users. Heavy newlinetrucks, buses trains, jet-planes, motor-cycles, scooters, mopeds, and jeeps etc have put newlinetremendous pressure on residents in congested cities with regard to increasing noise level. newlineNoise pollution is increasing as a result of increasing commercial and industrial newlineactivities worldwide, population growth, expansion of highways and increasing number of newlineautomobiles Noise is generally dependent mostly on the vehicles running conditions such as newlinethe quality of the engine and exhaust system, traffic flow, interaction with road surface and newlinetire and honking of horns. Other noise sources may be due to construction machine and newlinepublic address systems. Industrial noise is a noise associated with industrial processes that newlinemay cause hearing damage as a result of the high decibel level of noise, particularly among newlineemployees who experience consistent and prolonged exposures to noise. Measures for newlinecontrolling industrial noise are necessary in order to protect workers. Prolonged exposure to newlineunpleasant noises or even a pleasant sound which is too loud can lead to hearing impairment, newlinesevere mental disorientation and in s
