Abstract: A system for dissipating sound shock waves within a vehicle tire includes a wheel upon which a tire is mounted to create an internal air chamber defined by the wheel and the tire. A flow-resistant barrier is coupled to the wheel or the tire and defines an air cavity within the internal air chamber. A porous spacer can support the barrier with respect to the tire and also can provide a flexible energy damper. The barrier comprises a material that provides an acoustical resistance to sound shock waves passing therethrough. The air cavity defined by the barrier has a volume such that air within the cavity offers relatively small impedance to the passage of shock waves through the barrier and into the air cavity. The barrier also can produce frictional heat when displaced by a shock wave, thereby converting energy of the shock wave to heat to reduce noise associated therewith.
