Acoustic impedance values in the elderly
Journal of the American Auditory Society
|September 1, 1978
Abstract:
The purpose of this study was to evaluate the effects of age on acoustic impedance values in the elderly. Pure tone, otoscopic, and impedance testing were conducted with subjects from 20 to 29, 60 to 69, and 70 to 79 years of age. Results revealed a slight, but nonsignificant, tendency for static compliance values to decrease with age, suggesting that the use of separate compliance norms for the elderly may not be warranted.
