Extent of Hearing Loss Among Army Aviators at Fort Rucker, Alabama,
Abstract
This study provided hearing threshold data for Army aviators stationed at Fort Rucker, Alabama, from February through August 1982. The mean pure tone thresholds were found to be improved when compared to data gathered by Walden and McCurdy in 1971. This improvement partially was attributed to redesign of the aviation helmet and increased awareness and compliance with hearing conservation measures. It is possible that tighter administrative controls also contributed to the reduced threshold values. This study further indicated that, for Fort Rucker aviators, there exist three threshold regions correlated with flight hours: 50-400 flight hours, 401-3000 flight hours, and 3001-6000 flight hours. Each region has a specific range of hearing loss measured by comparing 2000 and 4000 Hz thresholds for the left ear. Anyone falling outside the threshold range for her/his respective region could be identified for possible follow-up procedures. (Author)
