Abstract:
A multi-layered noise absorbing and insulating material includes a noise insulation material having opposing first and second major surfaces. The noise insulation material includes an adhesive resin including an air permeability-forming material. A first noise absorption material is adhered to the first major surface of the noise insulation material. A second noise absorption material is adhered to the second major surface of the noise insulation material. The multi-layered noise insulation absorbing and insulating material has air-permeability.
