Parallel Noise Barrier Effectiveness
Publication No. FHWA-RD-90-105
Abstract: This report presents the results of testing on experimental parallel noise barriers constructed 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 barriers. It also evaluated the feasibility of modeling a moving point source with an artificial fixed-point source. The report is intended for highway traffic noise analysts.

Parallel Barrier Effectiveness Under Free-Flowing Traffic Conditions
Publication No. FHWA-RD-92-068
Abstract: This report presents the results of a measurement study performed at a highway noise barrier site located along I-495 in Montgomery County, Maryland. The objective of the study was to measure the degradation in acoustic performance of a highway noise barrier due to the close proximity of a parallel barrier on the opposite side of the roadway. The report is intended for highway traffic noise analysts.
