The influence of inclined buildings on road traffic noise

Abstract

Due to the scarcity of land in Singapore, it is inevitable that buildings are built close to the expressways, and buildings flanking both sides of the expressway are a common sight. Some buildings are less than 50 m from the kerb of the expressway. Intuitively, we could reduce the road traffic noise to the occupants of these high-rise buildings by inclining the buildings. The effects of the multiple reflections and diffuse energy would be reduced by inclining them. However, field measurements as well as the prediction models derived show that inclining the buildings, even by as much as 40 °, has insignificant influence on the road traffic noise. © 1995.
