Aircrew Helmet Noise Reduction Technology

DoD and MoD qualified for reduced noise exposure and improved helmet system performance

Gentex Corporation’s new aircrew helmet noise reduction (AHNR) technology is DoD and MoD qualified to reduce noise exposure for aircrew flying in louder aircraft and during longer missions. Available pre-installed in compatible helmets or field retrofittable, AHNR technology can be deployed in aircraft or battery-powered configurations, and at high and low impedances to enable use in all aircrafts. Adding or upgrading to AHNR technology in aircrew helmet systems improves aircrew hearing protection and overall system performance.
