Abstract: Theoretical and experimental studies are presented for the acoustic performance of parallel absorbent noise barriers in the presence of one or two parallel façade surfaces. A modified ray model has been developed to calculate the sound fields in these complex urban environments. The ray model has been validated by comparing with scale-model experiments and a wave-based computationally intensive numerical scheme. The barrier insertion loss is shown to be dependent on the source/receiver geometry, the acoustical property of the absorbent materials and the configuration of parallel noise barriers.
