Abstract:
OBJECTIVE:To evaluate the accuracy with which auditory steady-state response (ASSR), tone burst auditory brain stem response (Tb-ABR) and click-evoked auditory brainstem response (c-ABR) thresholds predict behavioral thresholds, using a within-subjects design.
METHOD:ASSR, Tb-ABR and c-ABR thresholds were recorded in a group of adults with normal hearing (58 ears). Evoked-potential thresholds were recorded and compared with behavioral, pure-tone thresholds.
RESULT:The results suggested both ASSR and Tb-ABR thresholds had high correlations to pure-tone thresholds. Tb-ABR thresholds were recorded much closer to behavioral threshold than ASSR thresholds. There was a linear relation between c-ABR thresholds and average thresholds of 2 kHz, 4 kHz pure tone audiometry.
CONCLUSION:Both the ABR and the ASSR provided reasonably accurate predictions of multifrequencies behavioral threshold. Tb-ABR combined with c-ABR may take the accuracy predicted behavioral threshold.
