3M strongly recommends personal t testing of hearing protectors. Research suggests that users may receive
less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in t, tting
skill, and motivation of the user. Refer to applicable regulations or guidance on how to adjust attenuation label
values. In the absence of applicable regulations, it is recommended that the attenuation rating be reduced to better
estimate typical protection.
