FM系统对不同信噪比下人工耳蜗植入儿童言语识别率的作用

摘要

目的：研究FM听觉辅助装置对人工耳蜗植入儿童的佩戴效果。方法对25名人工耳蜗植入儿童在安静和噪声环境中分别进行佩戴FM和不佩戴FM两种条件下的言语识别率测试，并进行相关统计学分析。结果①FM辅助和信噪比均存在的条件下，两者对言语识别率测试均产生明显的主效应；②相同信噪比条件下，佩戴FM辅助设备的听障儿童言语识别率明显高于未配戴者。结论建议植入人工耳蜗的听障儿童使用FM辅助装置进行康复训练，有助于增强融合教育效果。%Objective To study the effects of FM system on children with cochlear implants.Methods The speech recognition scores of 25 cochlear implant recipients with and without FM system were tested in quiet and noise. The results were statistically analyzed.Results (1) FM system and SNR had significant effects on the speech recognition scores. (2) Under the same SNR, the speech recognition scores of hearing-impaired children with FM system were significanly higher than those without FM system.Conclusion It is recommended that the children with cochlear implants use FM system in rehabilitation training,thus enhancing the efficacy of integrated education.
