目的评价老年人重度和极重度聋双耳助听效果。方法比较单耳和双耳助听后的言语识别率。结果 单耳助听后的言语识别率，单音节词为７７．５３±２．０７％，双音节词为８６．８２±４．３６％。双耳助听后的言语识别率，单音节词为８６．４７±１．８７％，双音节词为９１．６５±２．１８％。双耳助听效果显著优于单耳。结论双耳助听不仅可显著改善言语分辨能力，而且可使声源定向能力亦获显著改善。非常适合双耳重度和极重度聋的老年人。
Objective To evaluate the double hearing aids of severe and severe deafness in the elderly. Methods The speech recognition rates of single-ear and double-ear hearing aids were compared. Results Speech recognition rate after single ear hearing assisted hearing was 77.53 ± 2.07% for single syllable words and 86.82 ± 4.36% for dual syllable words. Speech recognition rate after binaural hearing aid was 86.47 ± 1.87% for single syllable words and 91.65 ± 2.18% for dual syllable words. Binaural hearing aid is significantly better than a single ear. Conclusions Binaural hearing aids can not only significantly improve speech resolution but also significantly improve sound source orientation. Very suitable for elderly with severe and severe deaf ears.
