项目摘要

We studied on Kansei reaction caused by audio-visual media information using physiological and psychological method. Especially we have interested in sound structure of audio information which caused Kansei reaction to humans.In this year, we examined the effect of high frequency components above the audible range. We set the cut-off frequency of 22kHz and 26kHz, and conducted physiological and psychological evaluation to find the difference between the two conditions. We found that a -EEG of the subjects increased when the high frequency components above the audible range was presented in both conditions. We also found that the sound with high frequency components persisted more comfortable to the ear.We presented the sound with natural fluctuation in micro temporal area and without this fluctuation structure, and conducted physiological and psychological evaluation, It is found that the sound with natural fluctuation stricture activated a -EEG of the subjects, however the sound without fluctuation structure did not. No sound difference between the two sounds was perceived by subjects.

运用生理学和心理学的方法对视听媒体信息引起的感性反应进行了研究。特别是我们对引起人类感性反应的音频信息的声音结构感兴趣。今年，我们研究了听觉范围以上的高频成分的影响。我们将截止频率设定为22 kHz和26 kHz，并进行生理和心理评估，以找出两种条件之间的差异。我们发现，在这两种情况下，当高于可听范围的高频成分出现时，受试者的a-EEG都增加。我们还发现，具有高频成分的声音对耳的持续舒适性更强，我们提出了在微颞区具有自然波动而没有这种波动结构的声音，并进行了生理和心理评价，发现具有自然波动结构的声音激活了被试者的a-EEG，而没有这种波动结构的声音则没有激活。两种声音之间没有声音差异。
