The influence of the sleep stage upon the morphology and the response threshold of the acoustically evoked 40Hz ERP (Event Related Potential) was studied. The results were as follows:(1) The amplitude of the 40Hz ERP was most prominent when the subjects were awake, and during their sleep state, the amplitude of the response dicreased as they fall into the deep stage.(2) The response threshold of the 40Hz ERP in the awake state was 10±5.5dB and in the sleep stage, 24±4.6dB. These facts suggested that the threshold discrepancy was approximately 13dB and it seemed quite stable among subjects.(3) These data drow our attention to apply the 40Hz ERP for screening test of hearing evaluation.
