Developing the algorithm for aircraft noise prediction on building façade

Abstract

Although the COVID-19 pandemic has now become an endemic, working remotely for certain days of the week remains adopted in many companies as the norm. As the air traffic is heavier during office hours, residents staying near to an airport may suffer the adverse effects of aircraft noise exposure relating to productivity and health. As this problem is present in many cities, aircraft noise prediction is important in aiding urban planning processes to identify and manage the problem accordingly. This paper presents our recent work on adding a new feature-important for interior acoustic comfort evaluation-to predict aircraft noise on building façade. The computational procedure involves processing the façade geometry from the 3D model, determining the line of sight between the façade and the aircraft, and generating the noise map. Eventually, this new feature will be integrated to a unified urban environmental modelling tool for the design of highly liveable and sustainable residential towns.
