On the effect of cross-hearing and clinical masking on the auditory brain-stem evoked response.
The effects of cross-hearing from the non-test ear were examined during the acquisition of the auditory brain-stem evoked response (ABR). Effective masking levels were derived from a normal hearing subject and the results used to obtain masked versus unmasked ABR thresholds in varying types of unilateral hearing loss. The results indicate that in the presence of a hearing loss adequate masking of the non-test ear is essential for valid ABR results.
