Comparison between auditory steady-state response and 40 Hz auditory event related potential in the evaluation of hearing thresholds / 法医学杂志

ABSTRACT

OBJECTIVE@#To compare the results between auditory steady-state response (ASSR) and 40 Hz auditory event related potential (AERP), and explore the accuracy of hearing thresholds by using ASSR and AERP and the clinic forensic value.@*METHODS@#Thirty seven ears were tested with pure-tone audiometer, 40Hz AERP and ASSR, respectively. All the volunteers in our study were awake during 40 Hz AERP test and ASSR test.@*RESULTS@#Thresholds acquired with ASSR and 40Hz AERP test had a close correlativity and showed higher than those acquired with PTA test. There was no significant difference between the accuracy of ASSR and 40Hz AERP in estimating pure-tone thresholds.@*CONCLUSION@#After determining the correct value, ASSR can be used directly to evaluate hearing loss objectively.
