ABSTRACT:
A laminate structure with improved acoustical absorption is provided which has a first and a third layer of foamed thermoplastic material and a second layer, intermediate the first and third layers, which is a material having acoustical properties different from the properties of the material of the first and third layers. A portion of the surface area of each layer is adhesively bonded to the adjacent layer. A sheet of paper or fabric is adhesively bonded to at least the outer surfaces of the first and third layers.
