To determine whether a large clinical group of cochlear implant (CI) recipients demonstrated a difference in sentence recognition in noise when using their pre-upgrade sound processor compared to when using the Nucleus 6 processor, and to examine the impact of the following factors: implant type, sound processor type, age, or onset of hearing loss.
A file review of 154 CI recipients (aged 7-92 years old) who requested an upgrade to the Nucleus 6 sound processor at the Cochlear Care Centre Melbourne was conducted. 105 recipients had complete data collected according to the protocol. A repeated measures, single subject design was used. Performance of CI recipients was compared with their pre-upgrade sound processor versus the Nucleus 6 processor using the Australian Sentence Test in Noise.
Group performance of CI recipients improved by 4.7 dB with the Nucleus 6 compared with the pre-upgrade sound processor. The benefit was not affected by pre-upgrade sound processor type or implant type (including older implant types and sound processors), age or onset of hearing loss (pre-lingual versus post-lingual).
This study confirmed that a clinical group of CI recipients obtained a significant benefit when upgrading to the Nucleus 6 sound processor.
确定一大群人工耳蜗（CI）植入者在使用升级前的声音处理器与使用Nucleus 6处理器时，在噪声环境下的句子识别能力是否存在差异，并研究以下因素的影响：植入类型、声音处理器类型、年龄或听力损失 onset。
对墨尔本人工耳蜗护理中心154名（年龄7至92岁）要求升级到Nucleus 6声音处理器的CI植入者进行档案审查。105名接受者根据方案收集了完整数据。采用重复测量单受试者设计。使用澳大利亚噪声环境下句子测试，将CI植入者使用升级前声音处理器与使用Nucleus 6处理器的表现进行比较。
与升级前声音处理器相比，CI植入者使用Nucleus 6时的组表现提高了4.7 dB。这种益处不受升级前声音处理器类型或植入类型（包括较旧的植入类型和声音处理器）、年龄或听力损失 onset（语前与语后）的影响。
本研究证实，一组CI植入者在升级到Nucleus 6声音处理器时获得了显著益处。
