A PLPREQ-20 from E-Pro is a safety earmuff used to reduce exposure to hazardous noise levels. It likely features electronic capabilities, such as an internal microphone and speakers, which can allow for ambient sound amplification while still providing noise reduction or for communication purposes.
The main benefits of using an E-Pro earmuff include superior hearing protection against damaging noise, enhanced situational awareness through electronic sound amplification or communication features, and improved comfort for extended wear. They can help prevent noise-induced hearing loss while allowing users to hear important sounds like warnings or conversations.
