User Acceptability and Comfort of the Communications Earplug (CEP) When Used in the UH-1 Helicopter,

Abstract

Aviators and crewmembers assigned to the crash rescue (FLATIRON) unit at Fort Rucker, Alabama participated in an evaluation of the communications earplug (CEP) in the aviation environment. They were asked to wear the two CEP configurations in combination with their personal SPH-4 helmet for three flights of at least 1 hour duration. One CEP configuration included a foam tip and the other included a premolded triple flange tip. Comments and responses provided by the volunteers showed the CEP, with some modifications, is acceptable for use in the aviation environment. Speech clarity of the CEP was judged to be an improvement over normal helmet/ear protection by 85 percent of the respondents. The CEP with foam tip was judged to be more comfortable than CEP with the triple flange tip. Comfort was judged to be between comfortable and mildly uncomfortable for the CEP with foam earplug tip. The volunteers rated the CEP as being helpful in achieving their mission. The results of this study show the CEP is comfortable and acceptable to the aviation crewmember.
