Abstract Human comfort is linked to health and work performance, and highly depends on the indoor environment. In this study, we studied total comfort in a combined environment by subjective evaluation and electroencephalogram (EEG). A discrete wavelet transform was used to analyze the EEG signals. The results show that thermal, acoustic, visual, and total comforts are significantly correlated and the indoor environments can significantly influence brain cortical activity. In a comfortable environment, the total EEG energy in the parietal lobe (P3, P4) was smaller than in an uncomfortable environment. When subjects felt comfortable, theta frequency-band in the frontal pole (Fp1, Fp2) was significantly increased. These metrics can be used as a biological marker that reflects total comfort in different environments.

不同室内环境下人体脑电图特征分析

摘要 人体舒适度与健康和工作绩效息息相关，高度依赖于室内环境。在这项研究中，我们通过主观评估和脑电图 (EEG) 研究了组合环境中的总体舒适度。离散小波变换用于分析EEG信号。结果表明，热、声、视觉和总体舒适度显着相关，室内环境可以显着影响大脑皮层活动。在舒适的环境中，顶叶 (P3、P4) 的总 EEG 能量比在不舒适的环境中要小。当受试者感到舒适时，额极（Fp1、Fp2）的θ频带显着增加。这些指标可用作反映不同环境中总体舒适度的生物标记。
