| Abstract(in English) | We investigated the relationship between sleepiness and amplitude of amplitude-modulation following response (AMFR) to find the best tone to raise awareness of sleepy drivers. In this study, auditory responses which were evoked by amplitude modulated tones whose carrier frequencies were 500, 1000, 4000, and 8000Hz were recorded in 16 subjects. Performance level was divided into three stages by using reaction time of psychomotor vigilance test, and the amplitude of AMFR was found to be decreased as the decrement of the performance in all frequency range. The high performance stages were further divided into two stages, those with alpha wave and without alpha wave. We found that auditory responses evoked by 500Hz AM tone in alpha wave state were smaller those in no-alpha state, but those evoked by the other AM tone were consistent. These results suggest that the high frequency tone could make drivers aware of their sleepiness. |
