A Study on the Creation of Comfortable Sound Environment

我们让健康的受试者听到玻璃竖琴的声音。并通过脑电和脑血流进行生理学评价，得出出汗的生理学效果。并采用SD法对心理效果进行心理评价。结果，由此产生的放松时间在心理评估和生理评估中的效果可以得到证实。从这些结果中，本研究证实了松弛效应是通过超声波范围的声音获得的。在本研究中，我们从视觉和听觉两个方面考察了对人体的影响。在本研究中，出现了仅使用视觉刺激在舒适状态下获得的生理现象。此外，在研究中，没有将其添加到呈现声中的超声波范围内。未来有必要对增加超声波射程声音的情况进行核实。

We was let in healthy subjects the sound of the glass harp. And this paper was physiological evaluation by EEG and cerebral blood flow, sweating a physiological effect. And this paper was psychological evaluation by the SD method psychological effect. A result, the effect of the resulting relaxation time in the psychological evaluation and physiological evaluation could be confirmed. From these results, the present study it was confirmed that the relaxation effect is obtained by the sound of the ultrasonic range.In this study, we examined the effect of the human body by visual and auditory. In this study, physiological phenomena obtained in comfortable state by the use of only visual stimulus was given appeared. Besides, in the study, it is not added to the sound of the ultrasonic range in presentation sound. It is necessary to verify the case of adding the sound of the ultrasonic range in the future.
