Analysis of traffic noise

Sahoo, S (2014) Analysis of traffic noise. BTech thesis.



Environmental noise is an undesirable byproduct of industrialization and urbanization. Although it is not noticeable, this unwanted or excessive sound makes a significant damage to human beings and has a hazardous impact on our environment. The noise sources we interact daily, perhaps the most fast-growing and difficult to avoid noise source is the noise emanating from transportation. Highway traffic noise is the major contributor of transportation noise. To measure the impact of noise, nowadays mostly used tool is drawing contour over a map. The objective of this work is (a) to draw the noise profile of Rourkela on different hours of the day (morning, noon & evening) and (b) to perform t-test that determines whether there is a statistically significant difference between the means of equivalent sound pressure level of morning, noon and evening. Most of the sound pressure level at different site was within permissible limit. The noise level during evening time was more than morning and noon. This is because of high volume of traffic is experienced in the evening.
