Abstract:
1. A system for dissipating sound shock waves, comprising: a tire that can be mounted to a wheel to create an internal air chamber defined by the wheel and said tire; a flow-resistant barrier disposed within the internal air chamber and defining an air cavity that is within the internal air chamber and that is between said barrier and said wheel, said barrier comprising a material that provides an acoustical resistance to sound shock waves passing therethrough, wherein said barrier comprises a plurality of layers disposed adjacent to each other, wherein each of said layers comprises a plurality of apertures, and wherein adjacent ones of said layers are disposed such that the apertures in adjacent layers are offset, and wherein the air cavity defined by said baffler has a volume such that air within the cavity allows the passage of shock waves through said barrier and into the air cavity.
