3M 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.
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.
