Abstract

To enhance the energy saving and comfort of indoors, this study performed a stimulation of sound fluctuation, color temperature, and aroma. The experiment with EEG, HRV, and Vibra images was conducted in an environmental test room with a temperature of $25[^{\circ}C]$, relative humidity of 50[RH%], air current speed of 0.002[m/s], and illuminance of 1000[lux]. The stimulation experiment set up different sensory stimulation conditions, such as before exposure, single-sensory stimulation of fluctuation a=1.106 jazz music, single-sensory stimulation of RED color lighting, single-sensory stimulation of scent aroma, and multi-sensory stimulation of fluctuation a=1.106 jazz music, RED color lighting, and scent aroma. After the multi-sensory stimulation of fluctuation a=1.106 jazz music, RED color lighting and scent aroma, the capacity for work and attention were increased, and the stress index and fatigue degree were decreased. In addition, multi-sensory stimulation of fluctuation a=1.106 jazz music, RED color lighting, and scent aroma were effective in maintaining a stable heart and health. In addition, the Vibra image appeared to decrease tension/anxiety and stress. The multi-sensory stimulation of fluctuation a=1.106 jazz music, RED color lighting, and scent aroma help increase the Neuro-energy more than that by no exposure and single-sensory stimulation.

본 연구에서는 에너지절감과 실내쾌적성을 높이기 위하여 색온도, 아로마 및 소리 변동리듬의 자극을 가하여 비교분석하였다. 온도$25[^{\circ}C]$, 상대습도 50[RH%], 기류속도 0.02[m/s] 및 조도 1000[lux]가 유지되는 항온항습실에서 뇌파, 심박동 변이 및 바이브라이미지가 측정되었다. 자극 종류는 자극을 가하기 전, 소리 변동리듬 a=1.106 재즈 음원으로 이루어지는 단일자극 그리고 붉은 조명, 아로마향기 및 소리 변동리듬 a=1.106 재즈 음원으로 이루어지는 다감각자극의 세종류로 측정이 이루어졌다. 변동리듬 a=1.106의 재즈 음원, 붉은 조명 및 아로마향기의 다감각자극에서 생산성과 집중력이 향상되었고, 스트레스지수와 피로도가 감소되었다. 또한 변동리듬 a=1.106의 재즈음원, 붉은 조명 및 아로마향기의 다감각자극에서 심박동이 안정되게 유지되었으며, 바이브라이미지의 긴장도와 스트레스 역시 감소되었다. 변동리듬 a=1.106 음원, RED조명 및 쟈스민 향기의 다감각자극이 쾌적성과 집중력 향상에 효과적이라는 것을 알 수 있었으며, 단일감각에 노출되기 전보다 뉴로에너지가 증가한다는 것을 알 수 있었다. 변동리듬 a=1.106 음원, RED조명 및 쟈스민 향기의 다감각자극이 자극을 가하기전보다 또한 단일감각자극을 가했을 때 보다 뉴로에너지가 증가된다는 것을 알 수 있었다.
