A Simulation-Based Method to Assess 3D Urban Noise Environment in High-Density Cities

摘要：

　　Urban noise is a major nuisance and health hazard in Hong Kong.Existing assessment methods are limited in their capacities; many do not apply to high-density cities.We developed a numerical model capable of assessing individual or household noise exposure in high-density cities.The purpose is to provide a tool for population-based health research and to inform urban planning decisions.The model is based on ray-tracing techniques.It takes into account geometric spreading,air absorption,material reflection coefficient and scattering properties of surfaces.The model is being evaluated in lab experiment and field measurement while the balance is held between accuracy and computing efficiency.Results showed that the new model allows us to assess noise exposure for individuals and households in high-density cities.
