Because of interactions between the signal processing and acoustic input, cochlear implant (CI) users' melodic pitch perception may be influenced by instrument timbre. In the present study, CI listeners' melodic contour identification was measured for six instruments (organ, glockenspiel, trumpet, clarinet, violin, and piano). While performance was generally best with the organ and poorest with the piano, individual CI subjects exhibited different patterns of results across instruments. CI subjects with the most music experience were less susceptible to timbre effects, suggesting that music training may help less experienced CI users extract melodic pitch from a variety of sound sources.
由于信号处理与声学输入之间的相互作用，人工耳蜗（CI）使用者的旋律音高感知可能会受到乐器音色的影响。在本研究中，测量了六类乐器（管风琴、钟琴、小号、单簧管、小提琴和钢琴）的CI使用者对旋律轮廓的识别能力。虽然总体上管风琴的表现最佳，钢琴最差，但各个CI受试者在不同乐器上呈现出不同的结果模式。音乐经验最丰富的CI受试者对音色效应的敏感度较低，这表明音乐训练可能有助于经验较少的CI使用者从各种声源中提取旋律音高。
