Abstract:
1. A method of manufacturing a wearable air blast wave energy protection device, the method comprising: (a) receiving a layer of a first material selected to provide a first reflective response to a specified incident air blast wave energy, the first material selected at least partially based on a first acoustic impedance of the first material to the specified incident air blast wave energy, and on a substantial mismatch between the first acoustic impedance and the acoustic impedance of air; (b) receiving a layer of a second material selected to provide a second attenuative response to the specified incident air blast wave energy transmitted through the first material, the second material selected at least partially based on an inelastic response of the second material to the specified incident air blast wave energy transmitted through the layer of the first material; and (c) joining at least a portion of the first material and at least a portion of the second material.
