Abstract: Using dichotic listening technique, in terms of articulation indexesand structure indexes of perceptual configurations of both ears in Chineseconsonants and lexical tones as analysis procedures, the experiment inve-stigated ear advantage in distinguishing consonant features and lexicaltones.The results showed that (1)the right ear advantage in consonantrecognition, the effect of sound levels on the lateralisation degree. (2) Theright ear advantage in distinguishing consonant features,(3) similarity inconsonant perceptual configurations and in distributions of consonants inthe two configurations of both ears, (4) no difference between performancein lexical tone recognition and resemblance in both ears in perceptual con-figurations of lexical tones.
