This study compares the musical perception of 17 adult recipients of the Nucleus cochlear implant using two different formant extraction processing strategies (F0F1F2 and MPEAK).
Over a 12 mo period, participants were alternately switched between two strategies every 3 mo. Performance was evaluated using three measures of rhythmic and sequential pitch perception.
Three individuals performed significantly better with the MPEAK strategy on one particular rhythm task, 11 participants performed better with the MPEAK strategy on another rhythm task, and no significant differences were found between the two strategies on a sequential pitch pattern task.
Neither strategy seems clearly superior for perception of either sequential pitch or rhythmic patterns.
本研究比较了17名使用两种不同共振峰提取处理策略（F0F1F2和MPEAK）的成人人工耳蜗植入者的音乐感知能力。
在12个月的时间里，参与者每3个月交替使用两种策略。使用三种节奏和顺序音高感知测量方法评估表现。
三名个体在一项特定节奏任务中使用MPEAK策略时表现明显更好，11名参与者在另一项节奏任务中使用MPEAK策略时表现更好，而在顺序音高模式任务中两种策略之间未发现显著差异。
对于顺序音高或节奏模式的感知，两种策略似乎都没有明显优势。
