Abstract

Road Traffic Noise is causing huge socio-economic losses to the nations all around the world by lowering the quality of life and property values. India, poised with the annual projected automotive industry growth of 12% to 15% for 2011-12 and ever increasing traffic on its roads draws serious concern related to traffic noise pollution. The noise associated with tyre-pavement interaction is known to be a major component of traffic noise. The paper addresses the influence of dimensional characteristics of tyres i.e. tyre section width and overall tyre diameter on the noise emission associated with tyre-pavement interaction. The principle focus of the study was to identify a conceivable trend showing not only the effect of tyre dimensions on tyre-pavement noise but also the extent of the influence. The tyres used for the study belong to C1 Class of tyres as per United Nations Economic Commission for Europe Regulation 30 (UNECE R30). For each set of tyres, the dimensional characteristics were first recorded and then the Coast-By Noise Measurement method in accordance with ISO-13325(2003) was employed to evaluate the tyre-to-road sound pressure emission level [SPL in dB (A)] on two different test sites. Based on the data obtained, a detailed analysis was carried out and the relation between tyre-pavement noise emission and said dimensional characteristics was established. The results were found to indicate that the on both test surfaces (rough), the tyre-pavement noise increases with increase in tyre section width and decreases with increase in overall tyre diameter. Plausible reasons in support of the results obtained were then identified and discussed.

Keywords: Sound Pressure Level (SPL), coast by, tyre section width, tyre overall diameter, aerodynamic noise, mechanical noise.
