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.
