- Smooth Foam for A Soft, Ultimate Fit
- Noise Reduction Rating NRR33
Noise Reduction Rating: 33 Decibels (when used as directed).
The range of noise reduction ratings for existing Hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness)
Information Required by EPA: 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:
- The environmental noise level as measured at the ear is 92 dBA.
- The NRR is 33 decibels (dB].
- The level of noise entering the ear is approximately equal to [92 dB(A) - 33] 59 dB(A).
Suggested use
- With clean hands, slowly roll plug into a thin, crease-free cylinder.
- While compressed, insert plug into ear canal. Fitting is easier if outer ear is pulled outwards and upwards during insertion.
- With fingertips, hold plug in place until it begins to expand.
