Abstract
ABRs are used to estimate hearing thresholds for different frequencies in infants who cannot tell us what they hear. The parallel ABR method (pABR) aims to speed up testing by presenting all the frequencies simultaneously to both ears. Randomly timed toneburst stimuli (very brief sounds) make it possible to acquire waveforms to the 5 frequencies in each ear. Previously, only wave V of the pABRs was characterized because that is the largest wave and can be used to reliably estimate threshold. The different component waves are best seen when the stimuli are presented at a higher level, or suprathreshold level. We are interested in characterizing all the component waves of pABRs, as they represent responses from different parts of the auditory system.
