• The efficacy of the frequency-selective auditory brain-stem response (ABR) in newborns and infants was assessed using an auditory stimulus of a 1-kHz tone pip and compared with the results of clickevoked ABR. In subjects whose responses to conventional behavioral audiometry were obtained at intensities of 40 to 70 dB, the ABR thresholds evoked by 1-kHz tone pips and clicks lay between 5 and 20 dB hearing threshold level (HTL). In subjects who did not respond to conventional behavioral audiometry at the intensity of 70 dB, ABR thresholds in each auditory stimulus were elevated by 35 to 70 dB HTL, and no responses were noted at 80 to 90 dB HTL. These results indicate that frequency-selective ABR can be applied clinically as an objective method of audiometry for newborns and infants.
