Abstract

In this study, survey experiment and EEG test was carried out to know the effect of visual images on EEG for evaluating words of soundscape sound source with 18 subjects. Analysis on the EEG were executed to know the difference according to with and without visual images. Followings are results of this study. 1) There is no big difference with visual images in soundscape sound evaluating adjectives such as "Full", "Clear", "Enjoyable" whereas there is a big difference in soundscape sound evaluating adjectives such as "Pleasant", "Comfortable", "Gentle", "Sonorous". 2) There is a tendency that soundscape sound source which is consist of single sound source shows + 1 above increase in survey test when visual image is suggested whereas soundscape sound source which is consist of one more sound source shows - 1 below decrease in survey test. 3) Statistical analysis was used to know considerable probability. ${\alpha}$-wave has a considerable probability and Maximum level difference occurring brain spots were number 1 and 2.
