器乐演奏家的皮层听觉诱发电位表明，音乐专业知识可以改变音调处理，但人们对声乐演奏家知之甚少。对61名年轻成年女性，包括20名声乐演奏家、21名器乐演奏家和20名非音乐人进行了音高偏差失配负值(MMN)和频率差阈值(DLF)的检测。刺激是来自中女性音域(C4-G4)的和谐音调复合体。MMN是由多变异范式引发的。DLF由适应性心理物理范式获得。音乐家比非音乐家更早察觉到音高变化，DFL比非音乐家小50%。声乐和器乐演奏家都拥有卓越的声学参数感觉记忆表示法。受过器乐训练的声乐音乐家似乎比只受过器乐训练或只受过声乐训练的音乐家具有听觉神经优势。一项偶然的发现表明，P3a是音乐专长的敏感指标。
Cortical auditory evoked potentials of instrumental musicians suggest that music expertise modifies pitch processing, yet less is known about vocal musicians. Mismatch negativity (MMN) to pitch deviances and difference limen for frequency (DLF) were examined among 61 young adult women, including 20 vocalists, 21 instrumentalists, and 20 nonmusicians. Stimuli were harmonic tone complexes from the mid-female vocal range (C4-G4). MMN was elicited by multideviant paradigm. DLF was obtained by an adaptive psychophysical paradigm. Musicians detected pitch changes earlier and DLFs were 50% smaller than nonmusicians. Both vocal and instrumental musicians possess superior sensory-memory representations for acoustic parameters. Vocal musicians with instrumental training appear to have an auditory neural advantage over instrumental or vocal only musicians. An incidental finding reveals P3a as a sensitive index of music expertise.
