Abstract:

This report describes the hearing of 34,091 military personnel within 13 Air Force Specialty AFSC known to constitute routine encounters with potentially hazardous noise. the smallest group contained 1049 persons, and the largest, 11,736. A total of 7678 22.5 of the entire sample revealed significant threshold shift. Cumulative percentages of annual audiograms along with median hearing levels are also described. The hearing levels in this study reveal that USAF use of significant threshold shifts to identify in the early stages, persons who are experiencing hearing shifts due to noise prevents significant hearing loss.
