Audiological assessment value of click-evoked auditory brainstem response combined with single stimulation of the auditory steady-state evoked response on normal young people

Objective: Analysis of normal young people multiple stimuli ASSR (m-ASSR), single stimuli ASSR (s-ASSR), C-ABR, PTA threshold, exploratory investigation of relevance of hearing test combination thresholds (C-ABR combines with 0.5, 1.0 kHz s-ASSR) predict behavioral thresholds, using a within-subjects design.

Methods: Forty-three normal hearing adults (86 ears) were treated with pure tone audiometry (PTA), m-ASSR, 0.5, 1.0 kHz s-ASSR, C-ABR. Data were analyzed by SPSS 18.0 for bivariate correlation analysis.

Results: There was significant correlation between thresholds of hearing test combination and PTA,and the correlation coefficient (r) were 0.803, 0.650, 0.649, 0.734 at 0.5, 1.0, 2.0 and 4.0 kHz; while the correlation coefficient (r) between thresholds of m-ASSR and PTA were 0.48, 0.64, 0.57, 0.64.

Conclusions: There is significant correlation between thresholds of hearing test combination and PTA, hearing test combination can be more accurate, more reliable assessment of adults with normal hearing threshold level.
