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 includes a first reflective-region having a first acoustic impedance substantially mismatched to air's acoustic impedance. The first material includes a second reflective-region having a second acoustic impedance substantially less than the first acoustic impedance. The device includes a second material configured to attenuate the specified incident air blast wave energy utilizing an inelastic response. The second material is configured for wearing proximate to a human body. At least a portion of a back surface of the first material is proximate to a front surface of the second material.
