Field Measure of Noise Through Select Means of Transport

Abstract

Mobility of people has significantly increased. Daily and occasional trips consume a significant time in our whole life span. A comfortable and safe travel is prime need of any individual. Noise is an important parameter which defines the quality of life. Vehicular noise not only affects the outer environment of the vehicle but it also causes discomfort for the occupants travelling inside the vehicle. Noise reduction during journey is an important aspect for a comfortable travel. We are constantly exposed to various types of noise generated from vibrations. These vibrations produce longitudinal waves which are intercepted by our ear. Sensitivity of our auditory system depends on various factors, and age of individual is an important parameter. Apart from this the exposure of noise during lifetime is important criteria for long term auditory functions. Exposure of noise during travel is gaining significant importance as it decides our comfort level, and sleep duration. In this paper we examine the noise pressure level (dBA) during travel through filed data collection. The trips discussed are on road, rail and air.
