  • Patent number: 4056161
    Abstract: The sound attenuation material disclosed in this application comprises, in its basic aspects, an outer layer, a sound absorption layer, and a sound barrier layer disposed between the sound absorption layer and outer layer and bonding them together.Over the years there have been developed a number of compositions, and laminated and coated articles, for use as vibration dampening and sound attenuation means. One such a sound and shock absorbing means is in the form of an adhesive tape and is shown in U.S. Pat. No. 3,217,832. The tape is manufactured by coating a woven webbing of plastic material such as nylon with a viscoelastic, tacky, filled composition comprising, inter alia, polybutene, petroleum oil, and barytes.
