Acoustics for people, International year of sound 2020-2021

CV:

Dr Linus Ang is currently a Research Scientist at the Institute of High Performance Computing (IHPC) under the Agency for Science, Technology and Research (A*STAR). In this role, his work focuses on developing aircraft noise map prediction capability for an in-house environmental modelling tool. Before his present role at IHPC, he was an Assistant Principal Engineer and Deputy System Head at ST Engineering. As a certified vibration analyst with more than 7 years of industrial experience, he worked on noise and vibration control in military platforms, leading various initiatives and product development through scientific research.

In 2013, he graduated from the Nanyang Technological University with a BEng degree in mechanical engineering. During the study, he was first exposed to acoustics through internship and final year project, focusing on acoustic testing and aeroacoustics, respectively. In 2019, he graduated from the National University of Singapore with a PhD degree in mechanical engineering. His research focused on acoustic metamaterials for low-frequency noise control, which was featured by the mass media and received recognition by the Acoustical Society of America (ASA) and the Society of Acoustics Singapore (SAS).

He has more than 10 publications in peer-reviewed journals including Applied Physics Letters and Applied Acoustics. He has also presented papers at 4 conferences including the International Congress for Sound and Vibration (ICSV) and the International Congress and Exposition on Noise Control Engineering (INTER-NOISE). He is currently the Guest Editor for a special issue on practical solutions for transportation noise mitigation in the built environment.

Title:

Remote work: Aircraft noise in the built environment amid COVID-19 pandemic

Abstract:

The COVID-19 pandemic has greatly changed workplace management with the adoption of remote work to minimize the risk of community spread. As such, housing estates remain largely occupied during office hours. Since some housing estates are situated in the vicinity of an aerodrome, noise pollution resulted from the takeoff and landing of aircraft is now noticed by residents, causing annoyance. Before the pandemic, such aircraft operations had minimal effect on the residents because most of them were not at home but at workplaces. Evidently, it is timely to place more emphasis during urban planning on the prediction and mitigation of aircraft noise in the built environment. In line with the theme of the International Year of Sound 2020–2021, this talk shares an overview of aircraft noise in the built environment amid the pandemic, how it can be predicted, and how it can potentially be mitigated to improve the quality of life.
