CEREBRAL responses evoked by sound can be recorded from the scalp using a computer to summate activity in the electroencephalogram (EEG) time-locked to repetitive sound stimuli. In normal subjects, and in subjects with hearing losses whose thresholds can be measured reliably with conventional audiometry, threshold for auditory evoked responses (AER) and psychophysical threshold agree within 5 to 15 db.1-5 The potential of this technique for assessing the sensitivity of the cochlea and peripheral auditory pathway in very young, uncooperative, or unreliable patients was immediately appreciated and is substantiated in several case reports and in three rather large series of infants and young children with brain damage and multiple handicaps.6-8

The object of this study is to emphasize that AER can be used to good advantage in children who are difficult problems because of persistently unreliable auditory thresholds and uncertain diagnosis.
