Scents may influence the perceived comfort of an environment. There are only a few studies conducted on the relationship between scent and comfort in aircraft cabin.
The goal of this research is to explore whether relationships between scents and perceived comfort can be found for passengers in an aircraft cabin.
276 participants joined an experiment in a Boeing 737 fuselage. The participants were divided into nine groups and each joined a session for 60 minutes with the exposure to different scents. The effect of the odor was measured by a set of questionnaires at the beginning and at the end of the session. Results of questionnaires were analyzed regarding the effects on the completion time, of the type of scents, of the intensity of the scent and on gender.
Significant differences were found at the beginning and at the end of the experiment regarding comfort and emotion, but sometimes no relations could be established. The influence of different scents on comfort/discomfort varied and changed over time. However, in all scenarios, participant' scores on emotion decreased. Additionally, the added scents influenced the linearity between the changes in comfort and discomfort.
Smell could influence the perceived comfort/discomfort of aircraft passengers over time, and different types of smells have different effects on passengers. The preferences on scents are diverse, which highlights the need for personalization in aircraft cabin design.
气味可能会影响人们对环境的舒适感。目前仅有少数研究探讨了飞机客舱内气味与舒适度之间的关系。
本研究旨在探索飞机客舱内乘客的气味与舒适度之间是否存在关系。
276 名参与者在波音 737 机身内参与了一项实验。参与者被分为九组，每组参加 60 分钟的实验，分别接触不同的气味。在实验开始和结束时，通过一系列问卷来测量气味的影响。分析问卷结果，了解气味类型、气味强度和性别对完成时间的影响。
实验开始和结束时，舒适度和情绪都有显著差异，但有时无法建立关系。不同气味对舒适度/不舒适度的影响是不同的，并且随着时间的推移而变化。然而，在所有场景中，参与者的情绪得分都下降了。此外，添加的气味会影响舒适度和不舒适度变化之间的线性关系。
随着时间的推移，气味可能会影响飞机乘客的舒适度，不同类型的气味对乘客有不同的影响。人们对气味的偏好各不相同，这凸显了飞机客舱设计个性化的需求。
