PURPOSE: to investigate the improvement in the performance and in the participation restriction of hearing aids users after a three-month period, as well as to find out a possible correlation between the results obtained in these two aspects. METHODS: 13 subjects having mild to moderate-severe sensorineural hearing loss, aged between 28 and 60 year old, were analyzed. The research of Sentence Recognition Threshold and Percent Indexes in Quiet and in Noise (SRTQ and SRTN, PISRQ and PISRN) was carried out in sound field through the Portuguese Sentences Lists test. The Hearing Handicap Inventory for Adults (HHIA) questionnaire was also applied. The first assessment was performed before the hearing aids fitting, without patients using them; the second, three months later, with the patients using the hearing aids. RESULTS: the statistical analysis showed a significant improvement not only in relation to participation restriction (HHIA) but also in the performance of assessments (SRTQ, SRTN, PISRQ PISRN). When correlating the improvement in participation restriction (HHIA) with the improvement in the other procedures, there was a significant correlation only between the improvement in HHIA and the improvement in SRTN. CONCLUSION: the assessed users showed a feeling of decreased participation restriction, and a performance improvement in situations of speech recognition in quiet as well as in noise. There was a correlation between an improvement in the answers to HHIA and SRTN due to the fact that most complaints in people with sensorineural hearing loss are related to the presence of competitive noise.
