Described embodiments include a system, device and method. A described device includes a first material configured to reflect a substantial portion of a specified incident air blast wave energy. The first material has an acoustic impedance substantially mismatched to air's acoustic impedance. A second material is configured for wearing proximate to a human body. The second material includes attenuating-regions. A first attenuating-region is configured to attenuate a first range of overpressures utilizing a first inelastic response. A second attenuating-region is configured to attenuate a second range of overpressures utilizing a second inelastic response. 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.
