Efeitos do envelhecimento da função auditiva em testes audiológicos
Goal: Evaluating the aging’s effect on hearing. Methods: Fifty elderly individuals (from 61 to 90 years old), being eight men and 42 women with high frequency hearing loss were evaluated.

| Resumo: | Goal: Evaluating the aging’s effect on hearing. Methods: Fifty elderly individuals (from 61 to 90 years old), being eight men and 42 women with high frequency hearing loss were evaluated. The patients underwent basic audiologic evaluation constituted by anamnesis, pure tone audiometry, speech audiometry, speech perception in noise test, transient and distortion product otoacoustic emissions. Results: The hearing loss complaint was present in a large portion of the sample and it was related to the hearing loss self perception to the difficulty of communication and also to the number of related difficulties. Concerning to the difficulty of communication, the presence of background noise was the more cited aspect. In the audiologic evaluation, women presented best thresholds within mild hearing loss degree. Age also interfered in the pure tone thresholds. The performance in the Speech Discrimination Test and Speech Perception in Noise were influenced by age, thresholds and hearing loss degree. In the transient and distortion product otoacoustic emissions, aging interfered in the obtained results and women were the only ones to present responses in the transient otoacoustic emissions and major ratio of responses in the distortion product otoacoustic emissions. The highest value of amplitude occurred in 2 kHz in the transient otoacoustic emissions and of 1,5 to 3 kHz in the distortion product otoacoustic emissions. Conclusion: Age negatively influenced the auditory function in both genders, affecting the auditory organ function as time goes on. Additionaly, we observed more deterioration of the Ogan of Corti function reflected as increased pure tone thresholds and poorest otoacoustic emissions responses. We also observe a difficulty in understanding speech, both in silence and with competitive noise. The impact of the deterioration of the auditory function with the age was more prevalent in men. |
