We examined age-related changes in the mean hearing level in 460 ears (81 males and 149 females) at intervals of ten years.
1) The average hearing level showed gradual deterioration at 125 Hz and 250 Hz.
2) The turning point for the worsening of hearing changes with aging.
3) The turning point exists at 1 kHz for men and women in their seventies.
4) The turning point exists at 2 kHz for men and women in their seventies.
5) The turning point exists at 4 kHz and 8 kHz for women in their fifties and sixties.
6) The turning point exists at 4 kHz and 8 kHz for men in their fifties and seventies.
Key words : normal person, aging, average hearing, male/female difference, multiple comparison
