结论：采用精细结构处理（FSP）编码策略的人工耳蜗（CI）和音频处理器对普通话被试的语音学习有显著的促进作用。成年汉语CI用户需要时间来适应他们的CI并体会到它的好处。目的：本研究旨在确定接受FSP编码策略的普通话成年人的语音感知结果。方法：前瞻性研究。本研究包括10名单侧植入PULSARCI100并接受OPUS 1或OPUS 2语音处理器的成年人。平均着床年龄为31.1岁。我们通过以下测试确定了重度至重度听力损失的普通话成人语后失聪的益处：安静单音节测试、安静句子测试和普通话噪音听力测试（MHINT）。使用音调感知测试评估音调感知。采用视觉模拟量表(VAS)对患者的音质和听音难易程度进行评分。结果：从第一次试合到第6个月，所有语音测试和音调感知均有显著改善。VAS评分显示，在6个月的时间里，声音质量有了显著的改善，听力的易用性也有了直接的改善。
Abstract Conclusion: This study indicates that Mandarin-speaking subjects acquire significant benefit from a cochlear implant (CI) and audio processor with the fine structure processing (FSP) coding strategy. It can take adult Mandarin CI users time to become accustomed to their CI and appreciate the benefits. Objectives: This study aimed to determine speech perception outcomes in Mandarin-speaking adults who received the FSP coding strategy. Methods: This was a prospective study. Ten adults who were implanted unilaterally with a PULSARCI100, and received an OPUS 1 or OPUS 2 speech processor, were included in this study. The mean age at implantation was 31.1 years. We determined the benefit to postlingually deafened Mandarin-speaking adults with a severe to profound hearing loss using the tests: monosyllables in quiet, sentences in quiet and the Mandarin Hearing in Noise Test (MHINT). Tone perception was evaluated using a tone perception test. A visual analog scale (VAS) was used to score sound quality and ease of listening. Results: The results showed a significant improvement between first fitting and 6 months in all speech tests and in tone perception. The VAS scores showed a significant improvement over 6 months in sound quality and an immediate benefit in ease of listening.
