Acoustic/shock wave attenuating assembly

An assembly for attenuating acoustic level pressure conditions, comprising

• a flowable attenuating medium exhibiting aqueous foam characteristics, namely the ability of acting in the nature of a liquid mass to resist relative displacement by surface tension and viscous forces and the ability to substantially scatter and disperse pressure conditions transmitting therethrough by virtue of multitudinous curved surfaces dividing different phases, and enabling the generation of turbulent flow fields by transmitting pressure conditions, and
• confinement means for containing and supporting the flowable attenuating medium, the combination of the confinement means and flowable attenuating medium being arranged for intercepting the pressure conditions to be attenuated, the confinement means being porous with respect to the pressure conditions for allowing the pressure conditions to penetrate the flowable attenuating medium, the porous confinement means also causing substantial pressure decrease of pressure conditions penetrating the porous confinement means,
• the attenuating medium being arranged in a honeycomb structure.

An attenuating panel for attenuating acoustic level pressure conditions, comprising

• multitudinous solid particulates having a dimension of at least about 1 millimeter, and
• filamentary material forming a matrix for the solid particulates,
• the filamentary material having mechanical integrity for providing confinement of the solid particulates in the matrix of filamentary material while allowing the solid particulates to be relatively displaced by interaction with the pressure conditions whereby the panel is capable of scattering and dispersing pressure conditions passing therethrough and further enabling formation of turbulent flow fields within the attenuating panel from the pressure conditions.
