The effect of stimulus intensity on the P300 component of the averaged auditory evoked potential was examined in healthy young adults. Although no effect on P300 amplitude was present, increasing loudness was inversely related to P300 latency. These data demonstrate a partial dependence of P300 on stimulus parameters, and underscore the importance of determining the hearing ability of subjects and patients in studies employing P300 as an index of information processing speed.
