as well as very loud impulse noises, such as gunfire. It is
difficult to predict the required and/or actual hearing protection
obtained during exposure to impulse noises. For gunfire, the
weapon type, number of rounds fired, proper selection, fit and
use of hearing protection, proper care of hearing protection,
and other variables will impact performance. To learn more

Please consult local directives for disposal of electrical and
electronic equipment.
LABORATORY ATTENUATION
The attenuation rating (SNR) was obtained with the device
powered off. Explanation of attenuation tables:
European Standard EN 352
Research suggests that users may receive less noise reduction
than indicated by the attenuation value(s) on the packaging, due
to variation in fit, fitting skill, and motivation of the user. Refer
to your applicable regulations for guidance on how to adjust
label values and estimate attenuation. In addition, 3M strongly
recommends fit testing of hearing protectors.
