Cochlear implants (CI) are effective in transmitting salient features of speech, especially in quiet, but current CI technology is not well suited in transmission of key musical structures (e.g., melody, timbre). It is possible, however, that sung lyrics, which are commonly heard in real-world music may provide acoustical cues that support better music perception.
The purpose of this study was to examine how accurately adults who use CIs (n = 87) and those with normal hearing (NH) (n = 17) are able to recognize real-world music excerpts based upon musical and linguistic (lyrics) cues.
CI recipients were significantly less accurate than NH listeners on recognition of real-world music with or, in particular, without lyrics; however, CI recipients whose devices transmitted acoustic plus electric stimulation were more accurate than CI recipients reliant upon electric stimulation alone (particularly items without linguistic cues). Recognition by CI recipients improved as a function of linguistic cues.
Participants were tested on melody recognition of complex melodies (pop, country, & classical styles). Results were analyzed as a function of: hearing status and history, device type (electric only or acoustic plus electric stimulation), musical style, linguistic and musical cues, speech perception scores, cognitive processing, music background, age, and in relation to self-report on listening acuity and enjoyment. Age at time of testing was negatively correlated with recognition performance.
These results have practical implications regarding successful participation of CI users in music-based activities that include recognition and accurate perception of real-world songs (e.g., reminiscence, lyric analysis, & listening for enjoyment).
人工耳蜗植入物（CI）在传递言语的显著特征方面非常有效，尤其是在安静环境中，但目前的 CI 技术在传递关键音乐结构方面（例如旋律、音色）效果不佳。然而，人们可能会认为，在现实世界的音乐中经常听到的歌词可能会提供支持更好音乐感知的听觉线索。
本研究旨在检查使用人工耳蜗的成年人（n = 87）和具有正常听力的成年人（NH）（n = 17）能够根据音乐和语言（歌词）线索准确识别现实世界音乐片段的程度。
CI 接受者在识别现实世界的音乐时，尤其是在没有歌词的情况下，准确性明显低于 NH 听众；然而，使用声学加电刺激的 CI 接受者比仅依赖电刺激的 CI 接受者（特别是没有语言线索的项目）更准确。CI 接受者的识别能力随着语言线索的增加而提高。
参与者接受复杂旋律（流行、乡村和古典风格）的旋律识别测试。结果根据以下因素进行分析：听力状况和病史、设备类型（仅电刺激或声学加电刺激）、音乐风格、语言和音乐线索、言语感知分数、认知处理、音乐背景、年龄，并与听力敏锐度和享受的自我报告有关。测试时的年龄与识别性能呈负相关。
这些结果对于成功参与包括识别和准确感知现实世界歌曲（例如，怀旧、歌词分析和欣赏音乐）在内的基于音乐的活动具有实际意义。
