摘要

There is a need to improve the insertion loss of a noise barrier without increasing the height of the barrier. In this paper, results of a numerical calculation study based on T-shapes of several kinds of barrier and with an acoustically soft surface are presented. By using an array of wells and adjusting the heights of the wells, improved insertion loss was achieved. Typical results for a T-shaped barrier with arrayed wells are presented.
