Abstract
An apparatus and method for evaluation of hearing loss is disclosed. The apparatus and method use evoked Auditory Brainstem Responses (ABR) to determine if the subject is able to hear click stimuli that are repeatedly administered. In order to facilitate efficient differentiation of the ABR from the accompanying noise, normative data is used to detect test conditions where physiological, non-physiological, and ambient acoustic noise would interfere with the progression of test.
