摘要：PURPOSE: Aging causes changes in the external ear as a collapse of the external auditory canal and tympanic membrane senile.Knowing them is appropriate for the diagnosis of hearing loss and selection of hearing aids.For this reason, the study aimed to verify the influence of the anatomical changes of the external ear resonance in the auditory canal in the elderly.METHODS: The sample consisted of objective measures of the external ear of elderly with collapse (group A), senile tympanic membrane (group B) and without changing the external auditory canal or tympanic membrane (group C) and adults without changing the external ear (group D).In the retrospective/clinical study were performed comparisons of measures of individuals with and without alteration of the external ear through the gain and response external ear resonant frequency and the primary peak to the right ear.RESULTS: In groups A, B and C was no statistically significant difference between Real Ear Unaided Response (REUR) and Real Ear Unaided Gain (REUG), but not for the peak frequency.For groups A and B were shown significant differences in REUR and REUG.Between the C and D groups were significant statistics to the REUR and REUG, but not for the frequency of the primary peak.CONCLUSION: Changes influence the external ear resonance, decreasing its amplitude.However, the frequency of the primary peak is not affected.
