该研究检查了成年人工耳蜗植入者在来自现实世界音乐的各种识别和评估测试中的表现是否可以从技术，人口统计和生活经验变量以及语音识别分数中预测。1985年至2006年期间植入的209名成年人的代表性样本参与了研究。使用多元线性回归模型和广义线性混合模型，选择了一组最佳预测变量，这些变量有效地预测了评估音乐听力不同方面的测试组合的表现。这些分析建立了区分音乐感知的准确性和音乐刺激的评价时，使用音乐听力作为植入成功的指标的重要性。重要的是，设备类型和处理策略都不能预测音乐感知或音乐评价。语音识别性能是不是一个强有力的预测音乐知觉，主要预测音乐知觉时，测试刺激包括歌词。此外，言语感知在预测音乐感知和评价方面的局限性强调了音乐感知作为评价植入物结局的替代结局指标的实用性。音乐收听背景、残余听力（即，助听器使用）、认知因素和一些人口统计学因素预测了感知准确性或音乐评价的几个指数。
The research examined whether performance by adult cochlear implant recipients on a variety of recognition and appraisal tests derived from real-world music could be predicted from technological, demographic, and life experience variables, as well as speech recognition scores. A representative sample of 209 adults implanted between 1985 and 2006 participated. Using multiple linear regression models and generalized linear mixed models, sets of optimal predictor variables were selected that effectively predicted performance on a test battery that assessed different aspects of music listening. These analyses established the importance of distinguishing between the accuracy of music perception and the appraisal of musical stimuli when using music listening as an index of implant success. Importantly, neither device type nor processing strategy predicted music perception or music appraisal. Speech recognition performance was not a strong predictor of music perception, and primarily predicted music perception when the test stimuli included lyrics. Additionally, limitations in the utility of speech perception in predicting musical perception and appraisal underscore the utility of music perception as an alternative outcome measure for evaluating implant outcomes. Music listening background, residual hearing (i.e., hearing aid use), cognitive factors, and some demographic factors predicted several indices of perceptual accuracy or appraisal of music.
