A cochlear implant (CI) restores hearing for profoundly deaf patients by transmitting sound to an array of electrodes that stimulates the inner ear. The small number of frequency bands and limited transmission of temporal fine structure affects the music perception. The present work investigates the pleasantness of chords and chord sequences in adults using such electric hearing. In the first task, participants compared chord types according to their perceived pleasantness. Normal-hearing listeners judged the major chord and the minor chord as the most pleasant ones compared to other chord types. CI users appraised the major chord as more consonant than other chord types. The second task used four-chord sequences, half of which ended on an authentic V-I cadence. In the other presentations, the final tonic was replaced either by a transposed major chord or by a dissonant chord. The participants had to judge whether the ending was conclusive. While normal-hearing listeners preferred authentic cadences, all but one CI user assessed the modified cadences as similarly satisfying. The results indicate that CI users appreciated consonance of isolated chords to a certain extent similar to normal-hearing listeners. Nevertheless, the majority of CI users fail to register the musical syntax in the harmonic progression of cadences.

电子听力中的音乐和谐

人工耳蜗（CI）通过将声音传输到刺激内耳的电极阵列来恢复重度聋患者的听力。少量的频带和时间精细结构的有限传输会影响音乐感知。本工作使用这种电听器研究成年人的和弦和和弦序列的愉快程度。在第一个任务中，参与者根据感觉到的和弦类型比较和弦类型。与其他和弦类型相比，听力正常的听众认为大和弦与小和弦是最愉快的。CI用户将大和弦比其他和弦类型更谐调。第二项任务使用四弦序列，其中一半以真实的VI节奏结束。在其他演讲中，最终的补音被移调的大和弦或不和谐的和弦代替。参与者必须判断结局是否是确定的。正常听力的听众更喜欢真实的节奏，但除一名CI用户外，其他所有用户都认为修改后的节奏令人满意。结果表明，CI用户在一定程度上欣赏了孤立的和弦的谐音，这与正常听者相似。但是，大多数CI用户都无法在节奏的谐调中注册音乐语法。结果表明，CI用户在一定程度上欣赏了孤立的和弦的谐音，这与正常听者相似。但是，大多数CI用户都无法在节奏的谐调中注册音乐语法。结果表明，CI用户在一定程度上欣赏了孤立的和弦的谐音，这与正常听者相似。但是，大多数CI用户都无法在节奏的谐调中注册音乐语法。
