The NRRs may overestimate the hearing protection provided during typical use due to variation in earmuff fit, earmuff fitting skill and motivation of the user. 3M recommends reducing the NRR by 50% for estimating the amount of noise reuction provided. The level of noise entering a person’s ear. when a hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example: 1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR is 25 decibels (dB). 3. The level of noise entering the ear is approximately equal to 67 dBA. Caution: For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the noise reduction rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the fitting instructions for proper fit.

FITTING AND ADJUSTMENT 2.1 Over the head position (figure D) (D:1) Slide out the earcups and tilt the upper part of the cups outward so that the wires are positioned away from the headband. (D:2) Position the earcups over your ears so that the cushions fully enclose the ears and seal tightly against the head. Adjust the height of each earcup while holding the headband down until you have a tight and comfortable fit that exerts even pressure around the ears. (D:3) The headband should sit straight on the head. 2.2 Behind the head position (figure E) For independent use with or without hard hats or caps.
