Short Description

 
Prof. Choy obtained her BEng degree with first class honour at the Department of Building Services Engineering, The Hong Kong Polytechnic University. After her graduation, she worked as an assistant engineer and engineer for nearly three years in Associated Consulting Engineers Limited which was one of the top three leading building services provider in Hong Kong. She then received her Doctor of Philosophy at the Department of Mechanical Engineering, The Hong Kong Polytechnic University in 2003. Thereafter, she was employed as a research assistant and research associate at the Department of Mechanical Engineering in 2003 and 2004 respectively and conducted the research of aeroacoustics. She then worked as a Lecturer in the Hong Kong Institution of Vocational Education, Tsing Yi in 2006. Prof. Choy joined The Hong Kong Polytechnic University again in 2007 as an Assistant Professor and was later promoted to Associate Professor in 2014. She has conducted various research and consultancy projects in noise and vibration control, flow and acoustics interaction, building acoustics, environmental noise control, Psychoacoustics and aural perception intervention, soundscape and headset design. Currently, she is Committee member of Women in Engineering (WIE) of The Hong Kong Institution of Engineers (HKIE). She is also serving as Associate Editor of The Journal of the Acoustical Society of America. Associate Editor of Noise & Vibration Worldwide, Guest Editor of Acoustics (MDPI), Editorial Broad member and Guest Editor of Applied Science, Lead Guest Editor of Journal of Low Frequency Noise, Vibration & Active Control and Guest Editor of Aerospace.
