To assess song recognition and pitch perception in prelingually deaf individuals with cochlear implants (CIs).
Fifteen hearing children (5-8 years) and 15 adults heard different versions of familiar popular songs-original (vocal + instrumental), original instrumental, and synthesized melody versions-and identified the song in a closed-set task (Experiment 1). Ten CI users (8-18 years) and age-matched hearing listeners performed the same task (Experiment 2). Ten CI users (8-19 years) and 10 hearing 8-years-olds were required to detect pitch changes in repeating-tone contexts (Experiment 3). Finally, 8 CI users (6-19 years) and 13 hearing 5-year-olds were required to detect subtle pitch changes in a more challenging melodic context (Experiment 4).
CI users performed more poorly than hearing listeners in all conditions. They succeeded in identifying the original and instrumental versions of familiar recorded songs, and they evaluated them favorably, but they could not identify the melody versions. Although CI users could detect a 0.5-semitone change in the simple context, they failed to detect a 1-semitone change in the more difficult melodic context.
Current implant processors provide insufficient spectral detail for some aspects of music perception, but they do not preclude young implant users' enjoyment of music.
评估语前聋人工耳蜗植入者（CI）的歌曲识别和音高感知能力。
15名听力正常儿童（5 - 8岁）和15名成年人聆听了熟悉流行歌曲的不同版本——原版（人声 + 乐器）、原版乐器版和合成旋律版——并在封闭式任务中识别歌曲（实验1）。10名人工耳蜗植入使用者（8 - 18岁）和年龄匹配的听力正常听众执行相同任务（实验2）。10名人工耳蜗植入使用者（8 - 19岁）和10名8岁听力正常儿童被要求在重复音调情境中检测音高变化（实验3）。最后，8名人工耳蜗植入使用者（6 - 19岁）和13名5岁听力正常儿童被要求在更具挑战性的旋律情境中检测细微音高变化（实验4）。
在所有条件下，人工耳蜗植入使用者的表现均不如听力正常听众。他们能够成功识别熟悉录制歌曲的原版和乐器版，并给予好评，但无法识别旋律版。尽管人工耳蜗植入使用者在简单情境中能够检测到0.5半音的变化，但在更困难的旋律情境中未能检测到1半音的变化。
当前的植入处理器在音乐感知的某些方面提供的频谱细节不足，但并不妨碍年轻植入使用者欣赏音乐。
