Abstract: Objective:To investigate the speech-evoked brainstem response (speech-ABR) of normal young people under different recording periods,which can provide the experimental evidences for researches on the stability of speech-ABR and promote its applications in clinical researches.Methods:40 healthy young people were randomly divided into two groups,which were tested following the same protocol at different time of two months interval.Latencies and amplitudes of the feature peaks in these groups were compared and the rates of appearance (detection rate) of the feature peaks were analyzed statistically.Results:Speech-ABRs were recorded successfully in two groups.The latencies and amplitudes of feature peaks in these groups were not different statistically,and the detection rates of V,A,C and F peaks were higher than others.Conclusion:The speech-ABRs of the two groups are stable,and the V,A,C and F peaks can be used as important indicators of clinical observation,showing that Speech-ABR is a promising tool in the study of Speech perception mechanism.
