Abstract : Conventional (.5, 1, 2, 3, 4, and 6 kHz) and high frequency (8, 9, 10, 11, 12, 13, 14, 15, 16, and 18 kHz) hearing was tested of US Navy aviators flying primarily prop, jet, or helicopter aircraft for varying amounts of hours. Results show a progressive decline in hearing as a function of number of hours flight time. They also reveal high frequency hearing to be most affected as well as earlier to deteriorate from noise exposure. These results suggest high frequency hearing testing could be of significant value in hearing conservation programs in early detection of loss and in evaluating effectiveness of hearing conservation measures.
