The auditory acuity of new-born infants was examined by means of an average response computer.Ten subjects were from 3 hours to 8 days of life.Tone bursts of 0.5, 1, 2, and 4KC at 30, 60, and 90 phon.were presented as auditory stimuli.Results were as follows:Above 60 phon.the average responses were obtained from almost all subjects at every frequencies used, but at 4KC it seemed less effective to evoke the responses.Typical response consisted of three positive-negative-positive phases and their latencies were somewhat longer than those of adults.Variations of the response pattern were observed among the subjects.
