- *U.S. EPA specifies the NRR as the measure of hearing protector noise reduction. However, 3M makes no warranties as to the suitability of the NRR for this purpose. 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 or guidance on how to adjust attenuation label values. It is recommended that the NRR be reduced by 50% to better estimate typical protection.

3M 1100 Earplugs are made with soft foam and a tapered design to help provide a noise blocking seal. These earplugs are easy to roll down and insert, with the foam softening with body temperature to improve comfort over extended use. One size fits most. Slow recovery foam gives the user time to get the compressed foam cylinder (rolled down earplug) into the ear before the foam fully expands to fill the ear canal. Available with or without cords to suit user preference. Dispenser packaging option available. This product is EARfit testable to help validate the level of protection the individual user is getting.
