Abstract

Vehicular noise is one of the most serious concerns regarding environmental noise pollution in residential areas; it is also one of the most prevalent sources of environmental noise. The noise produced by the tyre-road interaction has been singled out as one of the main contributors to bulk vehicular noise, it also the most difficult to control by conventional methods. This report covers all the progress made to date in identifying and modelling the discrete noise generation and amplification/reduction mechanisms responsible for bulk tyre noise. Preliminary research into the horn effect, a geometric noise amplification mechanism, aims to relate the amplification effect with tyre features. Initial simulations studying the effect of tyre shoulder and tread width on the sound pressure levels within the tyre-road horn region show a correlation between these factors. Also outlined is the future research plan and overall objectives of the research project.

About the Speaker

Mr Yasir Alam graduated from Monash University Sunway Campus with a Bachelor of Engineering (Mechanical) degree with First Class Honours in 2010. He joined the Master of Engineering Science (Research) program in October 2010. His research interest is in tyre noise with emphasis on numerical simulations of noise generating mechanisms. This seminar is arranged as part of the fulfillment of the Faculty’s requirements for candidature conversion from Masters to PhD.
