Thirty-four members of the Minnesota Orchestra were evaluated otologically and audiologically for hearing acuity for the frequency range 0.25 to 20 kHz. Members were grouped by age and sex. Median hearing thresholds for each group for each frequency were calculated and compared to currently available presbycusis tables for the frequencies 0.25 to 8 kHz and to statistically generated age/sex thresholds for the frequencies 9 to 20 kHz. An analysis of individual and median audiometric configurations for each age/sex group explored potential relationships between instrument and position in the orchestra and audiogram. Generally, median performance curves showed a 'noise notch' at 6 kHz and decrease of hearing acuity with age for all frequencies, but decrease was most dramatic in the extended high tones (9 to 20 kHz). Certain musician types did demonstrate greater characteristics of noise induced hearing loss.
