The parameters of normality in MLC to frequency-specific click and tone burst stimuli are analysed. Thirty four patients aged 15-50 with normal hearing revealed by preliminary subjective audiometry and impedance examination are examined for the following variables: threshold, latency, amplitude and repetitivity in response to click and tone burst stimuli. The audiometric and psychoacoustic thresholds were found to be closely connected. The MLC latency was in the 8-80 msec range as reported in the literature. Amplitude was neither significant nor reliable as a parameter since it varied so much from patient to patient, whereas the repeatability over time of these evoked potentials demonstrated their reliability. The results of this study confirm the view that MLC analysis is a valuable addition to the battery of diagnostic tests in routine use.
