SOUND-ABSORBING BARRIERS: MATERIALS AND APPLICATIONS

Christopher W. Menge, Neville A. Powers

Open publisher page 4 citations

Abstract

This paper discusses the use of roadside barriers to reduce the levels of traffic noise in nearby communities. It also discusses the need for barriers on both sides of a highway, the resulting degradation of barrier performance, and the need to incorporate sound-absorbing facings into barrier designs. In addition, it includes a general overview of sound-absorbing materials and an extensive catalog of suitable materials and systems as well as some popular misconceptions for reducing highway noise.
