This investigation examined the effects of the aging process on the adequacy of Eustachian tube function. Older adults presenting normal hearing sensitivity and sensorineural hearing loss and normally hearing young adults served as subjects. Eustachian tube function was assessed using electroacoustic immittance measurement. Tympanograms were analyzed relative to pressure and function (amplitude) changes after Eustachian tube testing. One-way analyses of variance and χ2analyses revealed no significant differences between groups and no significant relationships between group membership and tympanometric measures.
