論文概要:This study focuses on the health benefits of indoor environments, utilizing electroencephalogram (EEG) to investigate the effects of indoor acoustic and olfactory environments on the psychological and physiological responses of college students. By examining both single-factor and multi-factor influences, it provides a deeper understanding of stress recovery mechanisms, offering scientific insights for creating healthy living environments and enhancing human well-being.
Chapter 1 introduces the research, outlining the challenges of indoor environmental quality on college students' mental health and defining the study’s objectives.
Chapter 2 reviews EEG-based studies on indoor acoustic and olfactory environments, summarizing key characteristics, analytical methods, and research gaps while emphasizing the study’s innovation.
Chapter 3 establishes a standardized "stress-recovery" experimental framework, drawing on existing theories to guide future research.
Chapter 4 examines the effects of different sound on comfort and brain activity, emphasizing the restorative benefits of natural sounds and identifying key sound comfort evaluation metrics.
Chapter 5 investigates the impact of various aromas on stress recovery and brain activity, highlighting the restorative role of plant aromas and the moderating effect of gender differences.
Chapter 6 explores multisensory biophilic stimuli in stress recovery, analyzing synergistic sensory effects and their implications for indoor biophilic design.
Chapter 7 summarizes the findings.
In conclusion, this study uses EEG to examine the effects of sounds and aromas on college students' psychophysiological responses. It highlights natural elements' role in stress recovery, establishes a health evaluation framework, and offers insights for biophilic design and indoor environmental improvement.
