Impact and airborne
Researchers at Mapei have developed Mapesonic 2: a new, patent-pending, sound-reduction membrane for use in both residential (homes, apartments and condominiums) and light-commercial (office buildings) environments. Mapesonic 2 provides reduced transmission of both impact sound (footsteps, dropped objects, etc.) and airborne sound (voice, T.V., etc.) through floors. This product is claimed to be a next-generation technology that combines sound reduction with crack isolation in a thin, flexible, lightweight, load-bearing, fabric-reinforced, peel-and-stick membrane.
