【摘要】 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。更多还原

【Abstract】 Objective:To explore the property of sound gain of hearing aids when sensorial deafness patients got the optimal discrimination effect of speech after using hearing aids for more than one year. Methods: Through more than one year’s follow--up of 85 patients suffered from bilateral sensorial deafness (range in age from 6 to 90 years old) with unilateral hearing aids and debugging of hearing aids, the property of sound gain of hearing aids was analyzed when patients got the stable and optimal discrimination status of speech. Results: The average discrimintion rate of speech in 85 patients with hearing aids was 60±24%,the average discrimination rate of speech without hearing aids was 50+26%. The average of hearing threshold level (125Hz--8 000Hz) was 55 ±11dBHL in 85 patients. Conclusion: The correlativity in statistics on the discrimination rate of speech (Y) verse the hearing threshold level (X) in the 85 patients was Y=-0. 808X+ 104.更多还原
