Crescendo Shooting guards against hearing damage caused by the peak sound pressure level produced by automatic fire and single gun shots, artillery fire and explosions, reducing them to safe levels, less likely to cause long term hearing damage. Developed for military use and used by NATO soldiers, the Crescendo Shooting filter is ANSI IPIL certified for impulse noise up to 166 dB where it provides 33 dB of attenuation, ensuring optimum protection from the highest levels of impulse sound. When sound peaks are not present Crescendo Shooting provides low attenuation of ambient sounds, ensuring voice and background noise can be heard whilst maintaining sound directionality with the minimum occlusion effect, unlike foam, electronic and earmuff protection.
