  • 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: 

  1. The environmental noise level as measured at the ear is 92 dBA.
  2. The NRR is 33 decibels (dB]. 
  3. The level of noise entering the ear is approximately equal to [92 dB(A) - 33] 59 dB(A).
