Biography
Dr. Liangfen DU joined the Department of Building Environment and Energy Engineering, The Hong Kong Politechnic University, as an Assistant Professor in April 2024. Her research interests encompass noise reduction?enabling natural ventilation technologies, acoustic metasurfaces, sound prediction, and environmental noise control. She earned her second Master degree and a Doctorate in Acoustics from the Institut National des Sciences Appliquées de Lyon (INSA Lyon) in France in 2012 and 2016, respectively. Following her postgraduate studies, she joined JD Acoustic Pte Ltd in Singapore as an Acoustic Consultant. After gaining valuable industrial experience during her year at JD Acoustic, she returned to?academia, working as a research fellow at the College of Design and Engineering at the National University of Singapore (NUS) from 2017 to 2021. From 2021 to?2024, She continued her research fellowship at the School of Mechanical and Aerospace Engineering at the Nanyang Technological University (NTU) in Singapore.
Abstract
For residents grappling with disruptive effects of traffic noise, the immediate solution often involves closing windows or doors that face busy roads. However, this remedy simultaneously obstructs natural ventilation. In the post-COVID-19 era, there is a growing recognition of the profound significance of natural ventilation, as it offers a multitude of advantages, including the improvement of indoor air quality, the mitigation?of health-related risks, and the advancement of sustainable green building practices. In an effort to?address the dual challenge of noise reduction and natural ventilation, we have introduced three innovative technologies that enable both: acoustic friendly ventilation?window (AFVW), ventilated acoustic meta-barrier (VAMB) and ultracompact double layered acoustic grating (UDLAG). This presentation will provide an in-depth discussion on these three innovative technologies, spanning from the initial prototype design and fabrication stages to comprehensive evaluations of their noise reduction and natural ventilation capabilities.
