Normative values for brain stem auditory evoked potentials obtained by digital filtering and automatic peak detection.

A BAEP test which uses constant, high level click stimulation was developed for preliminary screening of patients with known or suspected problems in auditory information processing. Digital filtering and automatic peak detection were employed to aid in the analysis of BAEP component latencies. The results of 148 BAEP tests allowed us to select a set of normative measures: absolute peak latency, interpeak latency and left-right peak latency difference. The set of threshold values was developed for selected BAEP measures, in order to evaluate test results.
