Sound Barriers for Acoustic Insulation

Sound BarriersElasto Proxy explains what engineers need to consider when choosing sound barriers.  This article is the third in a multi-part series about acoustic insulation.

Sound barriers are soundproofing materials that reflect little or no noise. They usually contain dense but flexible mats and one or more layers of acoustical foams such as melamine. Various facing materials are also used for attenuation, protection, and decoration. Sound barriers are designed to achieve maximum attenuation over a broad frequency range, but they can impart other important properties. For example, some sound barriers offer resistance to fire and fluids. Other emit low levels of smoke while burning. (more…)
