  • Motor vehicle acoustic insulator, methods of manufacture and use thereof
    Patent number: 8881864
    Abstract: An acoustic insulator for a motor vehicle is provided comprising a mass providing an acoustic barrier and a spring providing an acoustic absorber overlying the mass. The mass comprises a first acoustic mass layer underlying a second acoustic mass layer. The first acoustic mass layer is provided by a thermoplastic sheet having a thickness in a range of 0.5 mm to 1 mm. The second acoustic mass layer is provided at one or more localized areas formed in place on a backside surface of the first acoustic mass layer to increase an overall thickness of the mass at the one or more localized areas. The spring layer is formed in place on a backside of the second acoustic mass layer and the backside of the first acoustic mass layer.
