title: Acoustic admittance of the ear in the geriatric person.
abstract: The effects of age on acoustic admittance in a geriatric population were investigated in persons ranging in age from 50 to beyond 70 years. The results demonstrated a significant decrease in admittance for the 70-year-old group, with the change being primarily attributable to a decrease in susceptance. Women consistently demonstrated lower admittance than men. The data obtained suggest that different norms for static admittance be applied to persons above 70 years of age.
