目的 :了解聋哑学生残余听力状态和配戴助听器的助听效果。方法 :对 3 8例聋儿进行纯音测听、声导抗检查、听性脑干反应检查及环境声辨别测试。结果 :气导语言频率平均在 89d B HL 以下 17例 ,90～ 110 d B18例 ,双耳 110 d B以上无反应 3例 ;A型鼓室图 3 3例 ,B型 5例 ;12 3 d B pe SPL 出现波形者 2 4例 ,无波者 14例 ;能辨别环境声者 16例 ,不能辨别者 2 2例。配戴助听器后能辨别者增至 2 4例 ,无效 14例。结论 :聋儿听力检测可发现有残余听力患者 ;
Objective:To explore the state of the remnant hearing of deaf mute students and to check the effect of hearing aids to them.Method:38 cases of deaf and dumb students were examined with the pure tone audiometry,acoustic immitance test,auditory brainstem response,and the environmental sound discrimination test.Result:In 17 cases,the average threshold of air conduction of speech frequency is below 89 dB HL;In 18 cases,it is between 90 dB and 110 dB;In 3 cases,it is above 110 dB.33 cases have model A curve and 5 cases have model B curve.When 123 dB peSPL was presented,24 cases generated the waveform but the others didn′t.16 cases could discriminate the environmental sound and the other 22 cases could not, but if the patients weared the hearing aids,the number of the persons who could discriminate the environmental sound increased to 24,only 14 cases had no effect by this means.Conclusion:Examination of deaf mutes audition can find persons with residual audition.If they wear the hearing aids and go into hearing rehabilitation training at the same time as early as possible,it will improve the environmental sound discrimination rate.
