Peltor COMBAT ARMS earplugs patented design allows wearers to more easily hear low-level sounds critical to mission safety ­ conversation, footsteps, rifle bolts. When needed, the earplug’s filter provides attenuation of high level noises like weapons fire and explosions.
Patented Dual-Protection Design
If the rocker cover is in Open/Weapons Fire mode (illustrated under 'More Pictures' tab), sound travels into the earplug and down the sound channel to the special filter. The filter allows lower-level sounds to pass with limited interruption but high-level impulsive noises are restricted. The more intense the impulse, the more it is limited. When the rocker cover is in the Closed/Constant Protection mode, the earplug provides an NRR of 23 dB.
