Abstract:
Objective The aim of the present study was to investigate the ability to perceive syllables phrases ,mono-syllabic words ,disyllabic words ,when using a CI and an HA in non -implanted ears (bimodal fitting) ,and the relationship be-tween aided thresholds in the HA ear and bimodal effectiveness .Methods Eighteen children who consistently used a bimodal fitting participated in the study .The loudness of speech in the HA ear matched that with implanted ear ,and the aided thresh-olds in the HA ear were obtained .The recognition rate of syllables phrases ,monosyllabic words ,and disyllabic words was tested under the aforementioned two modes in both the quiet and noisy backgrounds .Results The speech performance of children for monosyllabic words were 82 .67% ± 12 .23% ,83 .61% ± 12 .22% ,for disyllabic words 76 .00% ± 16 .13% ,78 .11% ± 14 .84% , for syllables phrases 60 .11% ± 17 .18% ,65 .43% ± 16 .76% ,with a CI alone or with bimodal fitting in a quiet environment ,re-spectively .In a noisy environment ,monosyllabic words were 75 .50% ± 14 .12% ,76 .83% ± 14 .15% ,and disyllabic words were 68 .22% ± 17 .15% ,77 .18% ± 16 .83% ,and syllables phrases were 49 .39% ± 19 .26% ,56 .33% ± 19 .55% .The results sug-gested that speech performance in a quiet or a noisy environment was significantly better with bimodal hearing than with a CI a-lone .All were statistically significant except the recognition rate of monosyllabic words in quiet background (P<0 .05) .Signifi-cant negative correlations were found between aided thresholds at 250 and 500 Hz ,and the bimodal advantages were noticeable for the some speeching perception .Conclusion Bimodal hearing enhances speech performance for deaf patients .The low -fre-quency residual hearing in the HA ear may play a major role in enhancing auditory and speech performance .
