[Study of hearing in normally-hearing elderly patients. I. Auditory threshold]

Through this paper the AA. examine 504 ears of 252 subjects of both sexes, between 60 and 84, all feeling subjectively normal regarding this sense, without otologic conditions in the past or at present. The explorations done were air and bone tonal audiometry. At the time the results were assessed, the coefficient of variability and standard deviation were kept in mind.
