Flents K30 Soft Foam Ear Plugs 4 Pairs

• Noise Reduction Rating - NRR 33 Decibels (when used as directed)

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).
