Damping Down the Decibels

This article addresses the use of sound barriers for applications in roadway noise abatement. Some salient features of such barriers include an uninterrupted surface, height of the barrier, aesthetic criteria, and a distance of no more than 61 meters from the roadway. One specific noise abatement product discussed in the article provides for materials that are resistant to corrosion, water, and rust in addition to being generally durable for most types of outdoor conditions. The barrier's outer surface is comprised of a synthetic shell that is stabilized against ultraviolet (UV) rays and integrates acoustically absorptive materials to diffuse sound waves. Another brand of sound barrier described uses laminated absorption elements that have a high decibel rating. The article concludes with a discussion on the use of ecologically-sensitive barriers that use recycled materials and attempt to blend in with surrounding landscape.
