Abstract
The disclosed acoustic insulator mat includes a first absorber layer made of a non-woven fibrous material. The non-woven fibrous material comprises a mesh of intertwined fibers that defines a plurality of cavities. The first absorber layer has a first side and a second side. Peripheral cavities are arranged along the second side of the first absorber layer between peripheral fibers. A coating is disposed on the second side of the first absorber layer. The coating is adhered to the peripheral fibers and thus includes a plurality of discontinuities at the peripheral cavities such that the coating provides a partial barrier to noise at the second side of the first absorber layer. The acoustic insulator mat may optionally include a second absorber layer that is retained on the first absorber layer by the coating. A method of manufacturing the acoustic insulator mat is also disclosed.
