PURPOSE: to assess the performance and satisfaction using hearing aids in patients assisted in the APAC-UFSM partnership, after a one-year fitting. METHODS: 49 subjects having mild to severe sensorineural or mixed hearing loss in the better ear were analyzed. They were divided into adults and elderly groups. The research of Sentence Recognition Threshold and Percent Indexes in Quiet and in Noise was carried out in sound field through the Portuguese Sentences Lists test; the satisfaction questionnaire, International Outcome Inventory for Hearing Aids (IOI-HA), was also applied. The tests were carried out in the same session, in two distinctive timeframes: the first one without using hearing aids, and the second one using hearing aids. RESULTS: there was a meaningful difference in both groups regarding the procedure carried out in silence. Although the performance in noise has not resulted in meaningful improvement, the patients had positive scores in the questionnaire. When comparing both groups, no significant difference in performance and satisfaction was observed. CONCLUSION: the meaningful improvement in silence agrees with the patients report. The questionnaire showed that most patients referred as making effective use of the hearing aids and having a very satisfying benefit. Although some patients referred a moderate or great residual difficulty, most of them considered that using hearing aids is really worthy.
