Design of Wood Highway Sound Barriers

摘要

As new and existing U.S. residential areas and high volume highways continue tointermingle, traffic noise abatement procedures continue to be important. This study investigated the acoustic effectiveness, public acceptance, and structural requirements of various designs and types of sound barriers. In addition, the acoustic effectiveness of a prototype sound barrier is reported. Results are presented on the acoustic effectiveness from in situ measurements of one cement-bonded composite panel barrier and four precast concrete, two plywood, two glued-laminated, and three post and panel barriers.
