Contribution of diffuser surfaces to efficiency of tilted T shape parallel highway noise barriers

Background and aimsThe paper presents the results of an investigation on the acoustic  performance of tilted profile parallel barriers with quadratic residue diffuser tops and faces.MethodsA2D boundary element method (BEM) is used to predict the barrier insertion loss. The results of rigid and with...
