ABSTRACT:
An acoustic/shock wave attenuating assembly comprised of porous screens forms an enclosure filled with a suitable pressure wave attenuating medium or material having fluid characteristics. This basic configuration can be suspended or held in place by a rigid structure. When the pressure attenuating medium is a liquid, the attenuating assembly is provided with a lining for containment. Multiple attenuating assemblies can be employed, with adjacent attenuating assemblies separated by a small gap. The pressure attenuating medium may be a liquid, a gas emulsion, an aqueous foam, or a gel (with or without entrained gas). Alternatively, solid particulates having bulk mechanical properties of a fluid may be employed as the pressure wave attenuating medium and may have an adhesive or the like resisting relative movement between particulates to simulate viscous effects. Elements of the assembly may incorporate materials which absorb thermal energy through endothermic chemical reactions, such as intumescent materials, to enhance the pressure attenuating effect.
