摘要

摘要: 目的:通过评估MED-EL人工耳蜗植入者使用FS4编码策略和HDCIS编码策略时的音乐音高和言语感知能力,探索提供精细结构信息的编码策略对人工耳蜗使用效果的影响。方法:12例植入MED-EL人工耳蜗的语后聋患者分别在FS4和HDCIS编码策略下编程调试,并进行音高差阈、音高方向和言语感知测试,比较2种编码策略下各项测试的结果,并进行统计学分析。结果:在FS4编码策略下的音高差阈和音高方向测试结果均显著优于HDCIS编码策略下的测试结果,测试得分差异有统计学意义(P<0.05)。2种编码策略下的汉语声调、声母和韵母识别得分均差异无统计学意义(P>0.05)。结论:FS4编码策略对人工耳蜗植入者的音乐音高感知有较大帮助。在汉语声调、声母和韵母识别方面,FS4和HDCIS编码策略的使用效果差异不大。

Abstract: Objective: To assess the performance of the new fine structure processing strategy(FS4) compared to the previous generation coding strategy HDCIS.Method: Twelve post-lingual hearing-impaired cochlear implant users were included. FS4 and HDCIS were compared in music pitch perception and speech perception test.Result: Acute comparison between FS4 and HDCIS showed that FS4 performed as well as HDCIS in speech perception tests, and outperformed HDCIS in music pitch perception.Conclusion: Results indicate that FS4 performs better than HDCIS in music perception. Differences between the two strategies were not significant for speech test.
