Simply pinch the grip between fingers and push to fit, which keeps the tip going into the ears clean even if hands are somewhat soiled with dirt, oil, grease, or some other contaminant. The unique, slow recovery foam is easy to fit in the earcanal with no roll-down required for a comfortable, noise-blocking seal. Assorted grip colors available. These soft polyurethane foam earplugs have a Noise Reduction Rating (NRR) of 25 dB and are test compatible with the 3M E-A-Rfit Validation System. Not only is noise present in our daily routines and recreational activities, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection. *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.
