This report examines five special noise barrier applications that exist in addition to the conventional vertical reflective barrier. The acoustic, aesthetic, and economic feasibility of absorptive T-top, Y-top, slanted-top, single-wall absorptive, and absorptive parallel noise barriers are addressed as they compare to a conventional noise barrier.
