PROTECHS™ Ear Plugs help to reduce loud volumes while preserving sound quality. These corded ear plugs are durable, reusable and they reduce sound levels by 27dB. The highs and lows are still there - they're just a lot quieter.

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 27 decibels (dB). 

(3) The level of noise entering the ear is approximately equal to [92 dB(A) - 27] 65 db(A). 

The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness).

Reach over the head and pull top of ear upward. With other hand grasp plug and gently push and rock into ear canal until a good seal is made.
