Abstract : The U.S. Army Aeromedical Research Laboratory (USAARL) participated in the development and testing of two emerging hearing protection technologies for Army aircrew members: communications earplug (CEP), and active noise reduction (ANR). Air Warrior is a program to develop the next generation, integrated, aircrew life support, and combat protection ensemble. The CEP or ANR may be part of the Air Warrior hearing protection strategy. This article compares the two technologies for compatibility with the Army aircrew member helmet and aircraft internal communication systems. In their current state of development, CEP provides better hearing protection, speech discrimination, and crash protection, lower weight and cost, and less need to modify existing aircraft systems compared to ANR.
