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.
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.
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]).
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.

音乐在频谱和时程内容上都是一种高度复杂的声学刺激。准确地表示和传递高保真信息对于音乐感知至关重要。然而，骨锚式听力植入物（BAHI）传输音乐的效果如何尚不清楚。本研究的目的是为 BAHI 用户和正常听力（NH）听众建立音乐感知性能基准，并比较两组的结果。
本研究为病例对照、横断面研究，纳入 18 名 BAHI 用户和 11 名 NH 对照。通过在七个主要音乐元素任务上的表现来评估音乐感知：音高辨别、旋律轮廓识别、节奏计时、基本节奏辨别、音色识别、复调音高检测和和声和弦辨别。
BAHI 用户在使用设备进行所有音乐感知任务时的表现与单侧使用较好耳时相当。BAHI 的表现与 NH 听众的表现无统计学差异。BAHI 用户在使用非植入侧控制耳时的表现与 NH 听众一样好，如果不是更好的话；除了节奏计时（BAHI 非植入耳 69%[95%CI：62%-75%]，NH 56%[95%CI：49%-63%]，p=0.02）和基本节奏任务（BAHI 非植入耳 80%[95%CI：65%-95%]；NH 75%[95%CI：68%-82%]，p=0.03）外，两组之间没有显著差异。
本研究代表了 BAHI 用户基本音乐感知性能的首次全面研究。我们的结果表明，BAHI 用户在音乐感知的主要元素中，使用植入耳的表现与使用对侧较好耳和 NH 对照组一样好。
