Abstract:

This study measured the magnitude of risk of the 1992 cohort of employees enlisted, officer, and civilian on the United States Air Force Hearing Conservation, Program by occupational codes Air Force Skill Codes, AFSC. Some 160,062 individuals that received annual audiograms during this period were eligible for analysis. To enhance precision, females were excluded from the study since they were less than 6 of the subcohort resulting in 151, 512 potential male employees to analyze. The study further restricted this group to view only the most recent audiogram for each individual that had a valid service and rank code. The final number of this subcohort was 107,421. Only AFSCs with 100 or more employees were analyzed. This represented 117 AFSCs with 93,854 audiograms 87.4 of 107,421. The age and race distribution of the 107, 421 audiograms were used as the standard for direct adjustment of each AFSC.
