Insertion loss of parallel wide barriers

Abstract

A ray method is proposed for predicting the insertion loss of parallel wide barriers, where some neighboring ones have same height. The method is based on the geometrical theory of diffraction and extended from an exact boundary solution for a rigid wedge. The model is available for arbitrary receiver locations, even on the shadow or reflection boundaries from the barrier top edges or being very close to the edges. The results from the simulations and the boundary element method are compared to validate the ray model, which shows that the model is considerably accurate for engineering applications.
