A device is described which gives a fast, reliable indication of the onset polarity of transient auditory stimuli. The instrument can be inexpensively constructed and is easily calibrated. It greatly simplifies the task of polarity calibration both in new equipment and in existing equipment after modifications have been made. This device will be of use to research laboratories and clinical departments who are currently recording auditory evoked potentials.
