Sound Amplification Earmuffs.
The Impact[TM] Sport Ultraslim Sound Amplification Earmuffs are designed to amplify ambient noise while also providing NRR 22 protection against hazardous noise. The product detects ambient sound and limits it to a level of 82 dBA, below the OSHA 85 dBA action level limit, while also amplifying lower levels to the same standard. Harmful noise is detected and blocked out by the same technology. The earmuff also comes with a baseplate chamber and high-tech non-woven layer that controls the flow of air to the ear, managing the qualify of sound that reaches the user.
