Music Perception in Bone‐Anchored Hearing Implant Users

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.
