Two research projects by ME researchers have been chosen as the winners of the HKIOA (The Hong Kong Institute of Acoustics) Acoustics Awards 2023 for their outstanding performance and contribution to the acoustics industry.
Product / Material Invention Category - Bronze Award
Awardee:
Dr Randolph LEUNG Chi Kin, Associate Professor, Department of Mechanical Engineering, The Hong Kong Polytechnic University
Awarded Project Name:
Novel Technology for Quantification of Tyre/Road Noise for Urban Noise Management
Project Description:
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.
Other Excellence Category - Merits Award & Student Award
Awardee:
Dr ARIF Muhammad Irsalan, PhD Graduate, Department of Mechanical Engineering, The Hong Kong Polytechnic University
Awarded Project Name:
Design and Development of a Novel Low Noise Airfoil / Wind Turbine Blade for Environmental Noise Reduction
Project Description:
The World Health Organization recognizing noise pollution as the second largest environmental contributor to health problems. Environmental noise can originate from diverse engineering applications, including the production of green energy, the building services industry, and aviation. The objective of the project was to develop an innovative approach to designing low- noise airfoils, capable of significantly reducing flow noise power while maintaining the original aerodynamic performance during operation. The outcomes of the project present a readily implementable concept that advances quiet technology for contemporary low-speed flow- mechanical systems, such as wind and tidal turbines, wings for small-to-medium-sized aircraft, and propellers for air taxis.
It is very encouraging to see that ME researcher and young alumnus from the Department were acclaimed by the Hong Kong Institute of Acoustics to further develop scientific research in cutting-edge technologies and made remarkable contributions to the community.
