Abstract:
1. A wearable air blast wave energy protection device, the device comprising: (a) a layer of a first material shaped and configured to reflect a substantial portion of incident air blast wave energy comprising a shock front originating from a high-order explosive, the first material having an acoustic impedance substantially mismatched to the acoustic impedance of air; and (b) a layer of a second material shaped and configured for wearing proximate to an exterior portion of a human body, the second material including at least two attenuating-regions, the at least two attenuating-regions including wherein the layer of the first material includes a front surface and a back surface, the layer of the second material includes a front surface and a back surface, and at least a portion of the back surface of the layer of the first material is proximate to at least a portion of the front surface of the layer of the second material.
