What are Combat Earplugs?
Combat earplugs are specially designed earplugs used by the military to protect members of the armed forces from high-level noises like weapons fire and explosions, and constant noise such as that from aircraft and armored vehicles, that could damage their hearing. According to the 3M website, “Combat Arms Earplugs (CAE) meet the demanding hearing protection needs of the armed forces. In the Open/Weapons Fire mode, CAE allows greater situational awareness than a common foam earplug yet helps attenuate dangerous peak levels with a filter element that reacts quickly to provide increased protection. In the Closed/Constant Protection mode, CAE protects against high-level steady noises like those in tracked vehicles and air transport.” Despite these claims, it has been found that 3M’s combat earplugs may contain a design defect that could put users at risk for hearing loss, tinnitus and other serious, debilitating problems. The earplugs at issue here are 3M’s dual-ended Combat Arms Earplugs, Version 2 (CAEv2) and, according to the whistleblower lawsuit, Aearo Technologies, Inc., acquired by 3M in 2008, was aware of the issue with the combat earplugs as early as 2000.
