- *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
- Pillow pack option for storage of earplugs between uses
Constructed from slow-recovery foam,the disposable earplug conforms to the shape of the ear canal for premium hearing protection.
These small earplugs are slightly smaller in diameter for a comfortable fit in smaller ear canals. Still one of the most widely used foam earplugs today, the 3M™ E-A-R™ Classic Earplug is an economical, reliable choice in hearing protection and conservation.
Suggested applications
- Poly bag keeps earplugs clean and accessible for re-use
