KANSEI SCIENTIFIC EVALUATION ON AUDIO-VISUAL MEDIA INFORMATION USING PHYSIOLOGICAL INDEXES

运用生理学和心理学的方法对视听媒体信息引发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。在这一年里，我们检查了高于可听范围的高频分量的影响。我们设置了22 kHz和26 kHz的截止频率，并进行了生理和心理评估，以找出两种情况下的差异。我们发现，当在两种情况下都出现高于可听范围的高频成分时，受试者的a-EEG增加。在微观时间区域呈现有自然涨落结构的声音和没有这种涨落结构的声音，并进行生理和心理评估，发现有自然涨落狭窄的声音激活了受试者的a-EEG，而没有涨落结构的声音没有激活。受试者感觉不到这两种声音之间的声音差异。

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.
