As a basis for determining the lower limit of acceptable humidity in an indoor environment, experiments were conducted for 25 subjects to assess the maximum expected sensations of dryness, discomfort based on humidity, and intolerance based on humidity, under conditions of 26°C and 10% RH. As results, distinct negative evaluations (dry, uncomfortable, or intolerable) were not obtained as the majority response; however, a small number of subjects declared distinct negative responses. In addition to the whole‐body evaluation, the sensations for individual body parts were collected and found to be more intense for the eyes, nose, throat, and lips than for the other body parts. Significant differences between the genders were not found. For 8 of the subjects, similar experiments under a condition of 30% RH were conducted, and the difference between two humidity conditions was clearer for discomfort and intolerance than for dryness. The results suggest that the evaluation of the specific individuals who respond intensely, the consideration of intense responses for a specific part of the body, and the careful selection of an evaluation word for a psychological response might be effective to link this study to the determination of the lower limit of indoor humidity.

室内湿度下限受试者心理反应实验研究.

作为确定室内环境可接受湿度下限的基础，对 25 名受试者进行了实验，以评估在 26°C 和 10 % 相对湿度。结果，明显的负面评价（干涩、不舒服或无法忍受）并没有作为大多数人的反应获得；然而，少数受试者声明了明显的负面反应。除了全身评估外，还收集了各个身体部位的感觉，发现眼睛、鼻子、喉咙和嘴唇的感觉比其他身体部位更强烈。没有发现性别之间的显着差异。对其中 8 名受试者，在 30% RH 条件下进行了类似的实验，与干燥相比，两种湿度条件在不适和不耐受方面的差异更明显。结果表明，对反应强烈的特定个体的评价、对身体特定部位的强烈反应的考虑以及对心理反应的评价词的仔细选择可能有效地将本研究与确定室内湿度的下限。
