Abstract
The military services use several types of small aircraft to perform a variety of missions. Most of these aircraft are obtained from commercial manufacturers and after receiving certain modifications, these vehicles are then used to accomplish a wide range of missions. This paper identifies primary and secondary sources of noise encountered within various utility type aircraft and features of bioacoustic and psychoacoustic concern are identified and discussed. Generally, three primary problems of aeromedical concern are evident in most of the aircraft studied; speech interference, potential auditory risk, and general fatigue induced by having to use increased vocal effort to achieve and maintain successful communications. Time (duration) files are also described that illustrate how the ambient noise environment changes with alterations in flight operations.
