However, what is the CCT increases for a given CCT to significantly increase the arousal level. In this experiment, each of 10 different CCTs (TA) having 325 ± 50 lux at subject’s eye level is increased to TM, where TM means the CCT induced significantly higher alertness than that induced by TA with p ≈ 0.05 and < 0.05. Using exponential function, interpolation, and c/p values of these 10 lighting conditions, we may estimate the corresponding TM for any given TA not in this experiment. Besides, ten adapted CCT lighting conditions and the corresponding marginal CCT conditions are determined by our experiment from these marginal CCT conditions. Music has the same influence on increasing the level of arousal, thus, this experiment adopted three different groups of lighting (0K, 3000K, and 6000K) and two types of music with different tempo (fast and slow) to explore their interaction. The result of the experiment shows that music has better effect on increasing arousal level than lighting with CCT increase 3000K; instead, lighting will work better than music with CCT increase 6000K.
