The E-A-R ARC Plug is designed to protect workers from the noise that results from arc flash that can cause hearing damage and concussive disorientation. It also has Hear-Through filter technology that allows the wearer to hear sounds clearly around them such as conversation, traffic, radio, etc. while receiving protection instantly in the case of an impulse noise like an arc blast. A second side (red) of the new ARC Plug offers protection against constant high-level noise (NRR 22dB).
