A Study on the Creation of Comfortable Sound Environment

我们让健康的受试者听玻璃竖琴的声音。并通过脑电图及脑血流量、排汗等生理效应进行生理评价。并采用SD法对心理效果进行心理评价。结果表明，由此产生的放松时间在心理评价和生理评价中的作用可以得到证实。从这些结果，本研究证实了松弛效应是由超声范围内的声音获得的。在本研究中，我们考察了视觉和听觉对人体的影响。本研究给出了仅使用视觉刺激在舒适状态下获得的生理现象。此外，在本研究中，并没有将其添加到呈现音的超声波范围的声音中。今后有必要对添加超声波范围声音的情况进行验证。

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.
