ANSI IPIL certified for impulse noise up to 166 dB where it provides 33 dB of attenuation. Developed for military use and used by NATO soldiers, these specialty filters are ANSI IPIL certified for impulse noise up to 166 dB where they provide 33 dB of attenuation. When no impulse noises occur, OtoPro Impulse earplugs provide low attenuation of only 5dB, permitting surrounding sounds and quiet conversation to be heard. By allowing air into the ear to reduce ear canal irritation, the wearer retains sound directionality and spatiality, critical in hunting situations. Combined with its small size and comfortable medical grade ear tips it is ideal for all day use, fitting unobtrusively under communications headsets or earmuffs. Medical grade TPE - hypoallergenic materials. For indoor ranges these should be used underneath earmuffs for optimum protection.
Rating systems explained:
IPIL - Impulse Peak Insertion Loss is a measure of sound reduction at the peak of an impulse blast. These earplugs provide over 33dB of reduction for a gunshot at 166dB.
NRR - Noise Reduction Rating is a measure of the softest level at which a steady-state sound is detected with and without the earplugs in place. These earplugs have a NRR of only 5dB as their goal is NOT to attenuate soft sounds but rather to keep those sounds audible while protecting from high level, impulse noises.
