Parallel Barrier Effectiveness: Dulles Noise Barrier Project

G. G. Fleming / E. J. Rickley

A test barrier was constructed in 1984 at a site at Dulles International Airport in Chantilly, Virginia. The study focused on the use of absorptive treatment and tilting as a means of improving the insertion loss of two parallel highway noise barriers. Results show: (1) the addition of absorptive treatment to the roadside face of two vertical, parallel, highway noise barriers eliminated multiple reflections and was found to improve the insertion loss (2 dB to 6 dB); (2) tilting proved to be an effective alternative to absorptive treatment in eliminating the multiple reflections and subsequent degradation in performance of two vertical reflective barriers.
