Induced Noise Pollution in the Vicinity of Urban Roadways – (Delhi): A Review

Abstract

Noise can be defined as the level of sound which exceeds the tolerable limit and causes irritatibility. Uninterrupted exposure to immense limit of noise can cause intense stress on the nervous and auditory system. Prolonged exposure to enormous sound has been proved psychological and physical damage. Due of its displeasure and interference implications, noise effects the general well-being and adds up psychological stress of those disclosed to it. Noise is a big cause of irritation among the people. The major originators of noise are the noise of Industries, noise of Traffic & noise of Communities. Out of three parameters above, vehicular traffic noise is the source that affects the most. 70% of noise in traffic noise is contributed by vehicle noise. Exhaust systems and engine of vehicles, interaction between the vehicles, aerodynamic friction, road system, and vehicle interactions cause traffic noise. The
road traffic noise model development is the main concern of the study.
