Abstract
An acoustic barrier for mounting to a barrier wall, such as a barrier wall between an engine compartment and a passenger compartment of a vehicle. The barrier wall has multiple indentations forming an uneven surface. The acoustic barrier comprises a decoupling layer and a mass layer. The mass layer has a series of projections formed on a rear surface, which coincide with the indentations of the barrier. When the decoupling layer is mounted to the rear wall of the mass layer, the projections alter the shape of the decoupling layer to conform with the shape of the barrier layer.
