Abstract:

Results of annual audiometric monitoring of 26,446 personnel 22,817 military and 3,629 civilian employees during January through March 1975 are reported. Mean and median hearing levels are reported separately for military and civilian personnel at test frequencies of 500 through 6000 Hz for right and left ears. Age groupings included in this study ranged from 17-19 and 5-year intervals thereafter up to age 49, with a final age group of 50 and older. Median hearing levels are reported for current annual and reference audiometric baseline audiograms. Results revealed that 98.9 of both left and right ears of 22,817 military personnel and 95.05 of left ears and 94.84 of right ears of civilian employees that routinely work in potentially hazardous noise showed hearing levels at 500, 1000, and 2000 Hz that averaged 30 dB or better.
