Dr Leung's awarded project is titled “Novel Technology for Quantification of Tyre/Road Noise for Urban Noise Management”. Road traffic noise is receiving increased attention in contemporary urbanized cities such as Hong Kong, for its wide-ranging detrimental effects on health, society, and the economy. With the rising popularity of EVs, tyre/road noise is recognized as the dominant contributor to traffic noise pollution. An advancement has been developed in enhancing the quantification capability of widely-used close-proximity (CPX) technology for measuring tyre/road noise on urban roads. This development enables real-time measurement of the sound power level of tyre/road noise, which represents an absolute metric for noise sources and is less susceptible to variations in the measurement environment in urbanized cities.
