Abstract
An acoustical barrier for blocking the transfer of sound through a barrier wall. The acoustical barrier comprises a sound absorbing layer and a decoupling layer mounted to the sound absorbing layer and spacing the sound absorbing layer from the barrier wall. The decoupling layer has a constructoin defining multiple voids to reduce the quantity of material used to construct the decoupling layer and to reduce the surface area of the decoupling layer contracting the barrier wall. Preferably, the decoupling layer has multiple protrusions such as ribs between which are interstitial spaces defining the voids.
