目的：比较17例成年人工耳蜗受者在F0F1F2和MPEAK两种不同峰提取处理策略下的音乐感知。设计：在12个月的时间里，参与者每3个月在两种策略之间交替切换。使用节奏和顺序音高感知三种测量方法来评估他们的表现。结果：3名受试者在一个特定的节奏任务中使用MPEAK策略表现较好，11名受试者在另一个节奏任务中使用MPEAK策略表现较好，在连续音高模式任务中两种策略之间无显著差异。结论：对于顺序音高或节奏模式的感知，这两种策略似乎都没有明显的优势。
Objective: 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).Design: 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.Results: 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.Conclusions: Neither strategy seems clearly superior for perception of either sequential pitch or rhythmic patterns.
