Respiration Induction by Music Control Based on Analysis of Carbon Dioxide Concentration by Multi-point Sensing

摘要

The latest study shows that various substances indoor have an adverse effect on the quality of human life. It was reported that a high concentration of Carbon Dioxide (CO2) has an adverse effect on human's intellectual activity. In order to improve our intellectual activities, we must clarify the diffusion of CO2 concentration from human breath by CO2 measurement units. In this study, we have measured and analyzed the diffusion of CO2 depending on human positions, the distance and heights in the room by simultaneous multi-point sensing. In order to control the amount of CO2 emitted from human breath, we examined using respiration induction that human breath frequency is controlled by music. The results show that CO2 from human breath diffuses throughout the room regardless of the position of persons, distance and height difference. We also have found that it is possible to influence CO2 emissions by respiration induction using monotonous music.
