目的：感音性耳聋者的纯音听力水平与选配助听器的声增益特性对言语识别率提高的讨论。方法：８５例６岁～９０岁双耳感音性聋者单耳选配耳背式助听器，经１年以上随访，对助听耳的纯音听力、最佳言语识别率、助听器的声增益特性进行分析。结果：８５例助听耳平均言语识别率为６０±２４％，裸耳言语识别率为 ５０±２６％，平均残留听力水平（１２５Ｈｚ～８ ０００Ｈｚ）为 ５５±１１ｄＢＨＬ。结论：８５例感音性耳聋者助听耳的言语识别率（Ｙ）与残留听力水平（Ｘ）之间的相关关系为：Ｙ＝－０．８０８Ｘ＋１０４。
Aims: To discuss the pure speech quality of sensorineural deafness and the acoustic gain characteristics of optional hearing aids. Methods: A total of 85 ear hearing-aided hearing-impaired hearing-impaired hearing-impaired hearing-impaired hearing-impaired hearing-impaired ears were studied in 85 patients aged 6 to 90 years. After more than one year of follow-up, hearing aural hearing, best speech recognition rate analysis. Results: The average speech recognition rate of 85 hearing aids was 60 ± 24%, the speech recognition rate of naked ears was 50 ± 26%, and the average residual hearing level (125Hz ~ 8 000Hz) was 55 ± 11dBHL. CONCLUSION: The correlation between speech recognition rate (Y) and residual hearing ability (X) in 85 patients with sensorineural deafness is: Y = -0.808X + 104.
