Sound barriers are custom acoustic insulation that blocks sounds instead of absorbing or damping them. They’re made of dense materials and are used at the source of a sound and along its path. To choose the right noise control product, engineers need to understand how sound barriers work, how they’re made, and the different types that are available.

Elasto 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. Continue reading Sound Barriers for Acoustic Insulation
