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介信息引起的感性反应进行了研究。我们尤其对引起人类感性反应的声音信息的声音结构感兴趣。今年，我们研究了高于可听范围的高频成分的影响。我们设置截止频率为22kHz和26kHz，并进行生理和心理评估，找出两种情况的差异。我们发现，在两种情况下，当出现高于可听范围的高频成分时，受试者的a -EEG增加。我们还发现，高频成分的声音对耳朵来说更舒服。我们将微颞区有自然波动的声音和不存在这种波动结构的声音进行生理和心理评价，发现有自然波动结构的声音激活了被试的脑电图，而没有波动结构的声音则没有激活。受试者感觉不到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.
