中文摘要：

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。

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.
