Abstract : A survey was made of pure-tone threshold audiograms of 2,246 flyers (pilots, navigators, and others) who were tested at the School of Aerospace Medicine during the years 1962 to 1965. Hearing levels were tabulated by percentiles for each age range, at eight audiometric frequencies and for right and left ear separately. These hearing levels were compared to those of another group composed of Air Force pilots only (tested during the years 1955 to 1962) and to hearing levels of the adult, male population of the United States as reported by the National Center for Health Statistics. The results indicate that hearing acuity decreases with age and increased pure-tone frequency (except at 8000 Hz), and that flyers have better hearing than does the general population but tend to lose hearing more rapidly at 6000 Hz.
