优点：现代人工耳蜗（CI）编码策略很好地表示了声音的时间包络，但提供的频谱信息有限。这种频谱信息的不足已经被认为是在嘈杂条件下难以进行语音感知的一个因素，区分说话者和旋律识别。为CI用户补充频谱信息的一种方法是将助听器（HA）安装到非植入耳。（一半与单侧CI和另一半与CI和HA（CI + HA））进行了测试的音乐感知和熟悉的旋律识别的措施。CI + HA的听众表现出显着优于CI的唯一的听众在所有基于音高的音乐感知任务。CI + HA组在两项依赖于持续时间线索的任务中的表现并不显著优于CI组。识别熟悉的旋律显着增强了一组戴HA除了他们的CI。这种优势在旋律识别增加时，旋律序列提出了与另外的harmony.CONCLUSION：这些结果表明，CI收件人在非植入耳aerobic听力，使用HA除了他们的植入物提高了感知的音高和识别现实世界的旋律。
OBJECTIVES: Modern cochlear implant (CI) encoding strategies represent the temporal envelope of sounds well but provide limited spectral information. This deficit in spectral information has been implicated as a contributing factor to difficulty with speech perception in noisy conditions, discriminating between talkers and melody recognition. One way to supplement spectral information for CI users is by fitting a hearing aid (HA) to the non-implanted ear.METHODS: In this study 14 postlingually deaf adults (half with a unilateral CI and the other half with a CI and an HA (CI + HA)) were tested on measures of music perception and familiar melody recognition.RESULTS: CI + HA listeners performed significantly better than CI-only listeners on all pitch-based music perception tasks. The CI + HA group did not perform significantly better than the CI-only group in the two tasks that relied on duration cues. Recognition of familiar melodies was significantly enhanced for the group wearing an HA in addition to their CI. This advantage in melody recognition was increased when melodic sequences were presented with the addition of harmony.CONCLUSION: These results show that, for CI recipients with aidable hearing in the non-implanted ear, using a HA in addition to their implant improves perception of musical pitch and recognition of real-world melodies.
