Managing Road Transport Noise through Control of Tire-Road Noise: An Indian Scenario

Tyagi, D. / Abhishek, Kumar / Mondal, P. / Vijay, P. / Bhangale, U. D.

The traffic noise has been a major source of discomfort to people for decades. Traffic noise is by far the most pervasive of all noises and over 80 million people are exposed to traffic noises of unacceptably high levels in the European Union alone. A major source of traffic noise is the noise generated due to interaction of rolling tire with pavement/road. In order to control this noise within the limits of comfort or regulatory requirements, improvement and engineering is required at both tire and pavement levels. Coast-by noise standards ISO 13325 (UNECE R117) was adopted for tire-road noise measurement purpose. With the introduction of more stringent rolling sound emission limits for new tire from 2012 in international market, a review of current state of sound emission levels emitted from new tire (C1 Category) available to Indian consumer for passenger car has been discussed in this paper.
