人脑的左半球通常在言语声的处理和复杂的语言功能上较右半球占优势;而大脑的右半球主要处理音调刺激和音乐声。大量证据表明大脑的左右半球处理听觉的区域根据声音的不同声学特征可能表现出特异性。以往研究对在听皮层水平侧别与声音刺激类型之间的关系已经作了深入研究,那么 The left hemisphere of the human brain usually predominates in speech processing and complex language functions over the right hemisphere; while the right hemisphere of the brain mainly deals with pitch stimuli and music sounds. There is ample evidence that the left and right hemispheres of the brain process auditory areas that may exhibit specificity depending on the different acoustic characteristics of the sound. Previous studies have examined in depth the relationship between the level of the auditory cortex and the type of sound stimulus, then
