3M 7000002321 | E-A-R 340-4003 Flanged Shape Elastomeric Polymer Regular EarPlug

3M E-A-R UltraFit Earplugs are made with a triple-flange design to contthis to the different shapes and sizes of ear canals to help create a comfortable noise-blocking seal. These earplugs are made of a pliable, soft polymer that can be washed so that the earplugs can be reused, cutting down costs and extending the product life. These durable, reusable uncorded earplugs are easy to use again and again, reducing waste. Push-to-fit products provide in-ear comfort and convenience, with the hearing protection you expect from 3M. The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is leading the advancement of hearing conservation.

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.
