Lecture: Effects of building geometry and materialization to reduce aircraft noise exposure in urban areas

Author(s): Lugten Martijn

Summary:
Air traffic emits noise and exhaust gasses causing nuisance and health stress for local residents around airports. In traditional noise computation used in noise mapping, the role of the built environment is neglected in order to keep the computational overhead acceptable. However, measurements around Amsterdam Airport show that building geometry has an effect on sound shielding. This study presents follow-up research in which it was studied how various design parameters can decrease noise levels in areas without a direct line of sight towards a flight path. The study included building height and façade porosity and varied these factors for different angles of incidence. The results show that increasing height and porosity levels increase the shielding properties of buildings. These effects become weaker with a larger distance between receiver and source. The results can be used to set guidelines for designers, planners and policy makers operating in airport regions.
