The top tracing in this case shows no recordable ABR to alternating polarity acoustic clicks at the maximum presentation level (100 dBnHL). The lower tracings also reveal no auditory brainstem potentials, but show clear cochlear microphonic responses to unipolar stimuli. The inconsistency between pre-neural (CM) and neural (ABR) findings is indicative of auditory pathway disorder in this case.
