A structure for attenuating explosive shock waves to prevent propogation of accidental explosions by sympathetic detonation of adjacent explosives comprising bidirectionally symmetric layers of material of consecutively increasing or decreasing acoustic impedance laminated about a center layer. The structure may be made by combining several materials, as in consecutive layers of aluminum, plastic, and a rigid foam surrounding on both sides a layer of steel; or, two material, as in a center layer of KevlarTMsurrounded on both faces with layers of plastic. The plies comprising the layer of KevlarTMare canted with respect to the plastic layers.
