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.

我们使用生理和心理学方法研究了由视听媒体信息引起的Kansei反应。尤其是我们对导致Kansei对人类反应的音频信息的声音结构感兴趣。今年，我们研究了高频成分以上高于听觉范围的效果。我们设置了22kHz和26kHz的截止频率，并进行了生理和心理评估，以找到两种情况之间的差异。我们发现，当在两种情况下呈现高于听觉范围的高频成分时，受试者的一个受试者增加。我们还发现，具有高频组件的声音在耳朵上持续更加舒适。我们在微观时间区域和没有这种波动结构的情况下以自然波动呈现声音，并进行了生理和心理评估，发现具有自然波动狭窄的声音激活了受试者的声音，但是没有波动的结构。受试者认为两种声音之间没有声音差异。
