This paper discussed the construct of evaluation in a combined environment of visual and auditory stimuli. In particular, we pointed out the relationship between a harmonious sensation of the two stimuli and comprehensive comfortableness. Ten subjects were asked to rate the image of twenty scenes on slides and sounds. In Experiment 1, they rated the individual image of each stimulus and in Experiment 2, they rated the combined image of the scene and sound.As a result of the experiments it became clear that the effect of a harmonious sensation on comprehensive comfortableness is not direct, but works indirectly through the evaluations "Calming" or "Pleasant." This indirect evaluation mechanism changes according to comfortableness of the combined stimuli. In a combination in which both stimuli are felt to be uncomfortable, although the stimuli are in harmony with each other, they are not felt to be "Calming" or "Pleasant," and therefore the comprehensive comfortableness is not high. On the other hand, when a comfortable stimulus is included, or when there is a great difference between the visual comfortableness and the auditory comfortableness, the harmony of the scene and sound caused the "Calmness" or "Pleasantness," and these combined stimuli are felt to be comfortable.

This study examined the combined effect of auditory and thermal factors in order to clarify the relationship between the comprehensive comfortableness and unspecific votes (impression of hot-cold, warm-cool and harmonious sensation vote).The main results are as follows; 1) The influence of the auditory factor on the comprehensive comfortableness and harmonious sensation votes tended to converge at low or high temperatures. 2) In various environmental conditions, the relationships between familiar-unfamiliar and the impression of hot-cold and warm-cool were approximately equal with the relationships between comfortable-uncomfortable and the impression of hot-cold and warm-cool. 3) The difference in the influence of auditory factor on the harmonious sensation vote varied was conspicuously depending on the degree of thermal factor stimulus.

The results showed that the slope of regression of hot-cold(unspecific scale) and the independent variable was temperature. The results showed that the slope of regression line of unspecific scale was small in comparison with specific scale in an arbitrary condition, and point of intersection of two sion line of unspecific scale was small in comparison with specific scale in an arbitrary condition, and point of intersection of two regression lines were different according to the environmental factors. The effect of attention was suggested. regression lines were different according to the environmental factors. The effect of attention was suggested.
