Service members are exposed to high noise environments on a daily basis. Aviation, mechanized, light and armored units are all exposed to environments well in excess of the permissible noise levels. In aviation alone, flight crews spend a majority of their day in aircraft and, even when not flying, are still subjected to the high noise levels of an active airfield. Ground crews carry headsets with them for aircraft run ups and maintenance checks. It is vital that these groups be able to protect their hearing while maintaining the ability to communicate effectively to accomplish the mission safely and effectively. Despite the availability of circumaural hearing protection systems for military personnel, the efficacy of these devices can be less than optimum. A major drawback can be the imperfect seal that the protector makes against the head and in addition, non-uniform pressure can lead to hot spots and discomfort especially after long periods of wear. Oceanit proposed to leverage its experience in materials and fabrication to realize a superior fitting hearing protection system. Commercial applications for next generation ear seals include passenger and cargo aircraft pilot and ground crew headsets, consumer hearing protection earmuffs, and comfortable cushioning with reduced pressure points.
