PURPOSE:
to evaluate sentence recognition in silence and in noise, by elderly individuals with symmetrical hearing loss, hearing aid users with monaural and binaural fitting, and to investigate which of the situations resulted in the best performance under conditions that simulate daily communication situations.
METHODS:
27 subjects were evaluated: 20 males and seven females, aged between 60 and 80, with moderately severe sensorineural hearing loss, based on mild and symmetrical configuration. Using the Portuguese Sentence List test, sentence recognition threshold was investigated in quiet and in noise as well as the percentage indexes of sentence recognition in silence and in noise, in different hearing situations, with binaural and monaural fitting.
RESULTS:
Average values for the indexes in silence were 80.89% with binaural fitting, 76.33% only in the right ear and 71.16% only in the left ear. The averages obtained in the noise levels were 62.05% with binaural fitting, 60.52% only in the right ear and 60.33% only in the left ear. The comparison of the different hearing conditions showed no statistically significant difference.
CONCLUSION:
No statistically significant difference was found among elderly hearing aid users with monaural and binaural fitting, both in silence and in noise.
