3M strongly recommends personal fit 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 fit, fitting skill, and motivation of
the user. Refer to applicable regulations and guidance on how to adjust attenuation label value(s). In the absence of applicable
regulations, it is recommended that the attenuation label value(s) be reduced to better estimate typical protection.
