Gupta Journal on Future Engineering and Technology 2230 – 7184 10 4 15 21 Traffic, Equivalent Noise Level, Noise Pollution Level, Traffic Noise Index The major contribution of traffic noise, towards overall noise pollution scenario, is a well known and established fact. Traffic noise from highways creates problem for surrounding areas, especially when there are high traffic volumes and high speeds. Vehicular traffic noise problem is contributed by various kinds of vehicles like heavy, medium trucks/buses, automobiles and two wheelers. Many western countries have developed prediction models based on L10, Leq and other characteristics. In India, the transportation sector is growing rapidly at more than 7.50% per annum and no. of vehicles on Indian roads is increasing at a very fast rate. These lead to overcrowded roads and cause various types of pollutions. Amongst these, Noise pollution is an important type which causes annoyance and health problems to human beings. This paper analyzes the measurement of traffic noise using the Noise Pollution Level, Traffic Noise Index and Equivalent sound levels by the application of noise level meter SL-4023- SD (with a Real Time Data Logger) for a period of 24 hours for up and down streams on a patch of NH-06. The major conclusions obtained are: higher the volume of traffic noise and speed of stream, the value of L10 varies directly. May - July 2015 Copyright © 2015 i-manager publications.
