Abstract: [ABSTRACT]OBJECTIVETo investigate the relationships between electrophysiological characteristic of speech evoked auditory brainstem response and Mandarin phonetically balanced maximum, so as to provide more clues for the mechanism of speech cognitive behavior. METHODSThe speech discrimination scores were obtained by Mandarin phonemic-balanced monosyllable lists via speech audiometric software in forty-one ears of normal hearing adults. Their s-ABRs were recorded with speech syllables da with the intensity of phonetically balanced maximum (PBmax). The electrophysiological characteristic of s-ABR, as well as the relationships between PBmax and s-ABR parameters including latency in time domain, fundamental frequency (F0) and first formant (F1) in frequency domain were analyzed statistically.RESULTS While divided the subjects into three groups by PBmax1= 100%, 100%
