Abstract：
OBJECTIVE: Music is a highly complex acoustic stimulus in both spectral and temporal contents. Accurate representation and delivery of high-fidelity information are essential for music perception. However, it is unclear how well bone-anchored hearing implants (BAHIs) transmit music. The study objective is to establish music perception performance baselines for BAHI users and normal hearing (NH) listeners and compare outcomes between the cohorts.
METHODS: A case-controlled, cross-sectional study was conducted among 18 BAHI users and 11 NH controls. Music perception was assessed via performance on seven major musical element tasks: pitch discrimination, melodic contour identification, rhythmic clocking, basic tempo discrimination, timbre identification, polyphonic pitch detection, and harmonic chord discrimination.
RESULTS: BAHI users performed comparably well on all music perception tasks with their device compared with the unilateral condition with their better-hearing ear. BAHI performance was not statistically significantly different from NH listeners\' performance. BAHI users performed just as well, if not better than NH listeners when using their control contralateral ear; there was no significant difference between the two groups except for the rhythmic timing (BAHI non-implanted ear 69% [95% CI: 62%-75%], NH 56% [95% CI: 49%-63%], p = 0.02), and basic tempo tasks (BAHI non-implanted ear 80% [95% CI: 65%-95%]; NH 75% [95% CI: 68%-82%, p = 0.03]).
CONCLUSIONS: This study represents the first comprehensive study of basic music perception performance in BAHI users. Our results demonstrate that BAHI users perform as well with their implanted ear as with their contralateral better-hearing ear and NH controls in the major elements of music perception.

摘要：
目的：音乐在频谱和时间内容上都是一种高度复杂的声学刺激。高保真信息的准确表示和传递对于音乐感知至关重要。然而,目前尚不清楚骨锚式听力植入物（BAHIs）如何传输音乐。研究目的是为BAHI用户和正常听力（NH）听众建立音乐感知表现基线，并比较队列之间的结果。
方法：病例对照，我们在18名BAHI使用者和11名NH对照者中进行了横断面研究.通过对七个主要音乐元素任务的表演来评估音乐感知：音高歧视，旋律轮廓识别，有节奏的计时,基本节奏歧视，音色识别,复音音调检测，和弦辨别。
结果：BAHI用户使用其设备在所有音乐感知任务中的表现与听力更好的单侧状况相比相当好。BAHI表现与NH听众的表现无统计学差异。BAHI用户的表现也一样好，使用对照对侧耳时，如果不优于NH听众；除了节律性时机外，两组之间没有显着差异（BAHI非植入耳69％[95％CI：62％-75％]，NH56%[95%CI：49%-63%]，p=0.02),和基本节奏任务（BAHI非植入耳朵80％[95％CI：65％-95％];NH75％[95％CI：68％-82％，p=0.03])。
结论：这项研究代表了对BAHI用户基本音乐感知表现的首次全面研究。我们的结果表明，在音乐感知的主要元素中，BAHI用户的植入耳朵表现与对侧听力更好的耳朵和NH控制一样好。
