摘要

Abstract

<正> The auditory brainstem response （ABR） was measured for 90 cars of norml gui-nea pigs

from which the mean latency

amplitude and recognition of waves were obtain-ded.The waves were classified into six types

with wave Ⅲ as the main wave which ac-counted for 77.1% of all the waves.The frequency domain of each type was analysed bymeans of digital filtering and auto-regressive （AR）estimation.The main frequency com-position of ABR in the guinea pigs was restricted within 1600 Hz

in which there werethree peaks at AR spectrum

the mean value of the peaks being 107.33 Hz

566.67 Hzand 1076 Hz respectively.The AR spectrograms of all types waves were very similar toeach other.
