In previous combined environmental evaluation reports, we studied the combined effect of the visual and auditory factors and the thermal factor to clarify the "nonspecific scale" (impression of "hot-cold" and "warm-cool") using regression analysis (objective variable: temperature, explanatory variable: nonspecific scale). As a result, the regression slopes representing the impression of "hot-cold" and "warm-cool" to temperature decreased and these shifts suggested that the "attention resource", distributed by the temperature, decreased due to the influence of the visual and auditory factors.
It may be suggested that this reaction is shown conspicuously in the "nonspecific scale". However, few reports are available on this subject and there are almost no reports that mention the relationships between the "attention distribution" and the "comfortable - uncomfortable" factor. Furthermore, it has been reported that the comprehensive comfortableness factor, "comfortable - uncomfortable", has a close relationship to the "harmonious sensation vote". Therefore, it is necessary to include the "harmonious sensation vote" factor when evaluating the relationship between the comprehensive comfortableness factor and the effect of the environmental factor.
Therefore, in this study, the authors recognized that the thermal and auditory factors can influence the comprehensive comfortableness factor, "comfortable - uncomfortable", from the point of view of the relationship between that factor and the impression of "hot-cold" and "warm-cool". The following findings were found.
(1) One-way analysis of variance was employed to clarify the relationships between the "comfortable - uncomfortable" and "harmonious sensation vote" factors and temperature. As a result, neither factor showed any difference in the effect of the auditory factor in either low or high temperatures. However, the two temperature ranges did show one significant difference, in the "distribution of the attention", which may be related to the "moderate stress region (Wyon, 1970).
(2) Comparing the comprehensive comfortableness votes, "comfortable-uncomfortable", and "familiar-unfamiliar" in the figures, both were thought to be similar, to a considerable degree.
(3) Regression analysis was used to clarify the differences between the auditory groups. (objective variable: impression of "hot-cold" "warm-cool", explanatory variable: "comfortable - uncomfortable"). As a result, the cooler auditory group had a larger influence on "comfortable - uncomfortable" than BG (background condition), in cases where the impression of "hot-cold", "warm-cool" and "comfortable - uncomfortable" showed liner relationships. However, the warmer auditory group showed a smaller regression slope, compared with the BG, suggesting that the influence of the attention and thermal factors was related to the difference in the regression slopes.
(4) This study investigated the relationship between "comfortable - uncomfortable" and " harmonious sensation vote" using the one-way analysis of variance. The results showed that the auditory factor influenced the "comfortable - uncomfortable" factor in an out-of-harmony environment. However, there was no influence in a harmonious environment. The reason for this difference may have been an interaction between the "harmonious sensation vote" and the auditory factor.
