Abstract
A noise barrier proposed in this paper which is based on the working principle of resonance in cavity and coupled with the edge effect of noise barrier. This barrier can provide significant noise attenuation for low frequency noise. The geometry of barrier is a kind of hollow round top edge barrier with slit on its edge and a cavity is then formed inside the top edge of barrier. Numerical simulation by Finite Element Modeling Method is done to predict the performance of barrier. Experiments with scale down model are carried out to compute the performance of barrier. The results show that this resonator barrier provides a high insertion loss on a specific range of low frequency noise in shadow zone.
