Barrier Fundamentals. A sound barrier is a solid structure that intercepts the direct sound path from a sound source to a receiver. It reduces the sound pressure level within its shadow zone.
IAC Acoustics Noishield outdoor sound barrier systems protect communities and workers from noisy equipment by blocking line-of-sight sound transmission and absorbing sound energy radiating from the source.
Apply to new or existing wood, concrete or steel barriers to reduce reflected noise levels in the community. Retrofit existing barriers to eliminate or mitigate noise complaints. Low weight, rugged construction ― ideal for retrofit applications. Laboratory-rated sound absorption coeficients.
This document discusses outdoor noise barriers, including their fundamentals, attenuation calculations, design considerations, and structural issues. It provides information on how barriers work to reduce sound levels, how to calculate their effectiveness, and practical limitations.
ABSTRACT. This study explores the use of concrete masonry walls employed as sound barriers for highway noise reduction. Concrete masonry is a widely used material in construction but its ability to effectively work as a sound barrier is understated.
Precast concrete sound wall systems, when manufactured and installed properly, will outperform and outlast systems consisting of competing materials. With the increasing regulatory demands for structurally sound precast sound wall systems, it is critical for precast manufacturers to continually raise the bar on quality.
architect or contractor select the acoustical wall design that is best for a specific situation, a wall design that includes Owens Corning FIBERGLAS PINK ® Insulation.
