The influence of inclined roads on the acoustical performance of building facades with balconies close to roadways has been investigated. Various inclined angles and a building facades with lm balconies have been modeled on a 8 floors building. Pyramid ray-tracing simulations and scale model measurements have been carried out. The predicted and measured A-weighted sound pressure level reductions over the balcony back wall and in free field conditions have been compared. The results have been used to predict the protection obtained by various inclined roads. The protection obtained ranges between 0.5 and 4 dB(A).
