気温と騒音が青年女性の快適感と受容感に及ぼす影響 複数物理環境条件下における環境規準の開発 その1

摘要

The purpose of this study is to propose new environmental standards by reflecting the combined effect of temperature and noise stress on the human state of mind. Twenty-three female students were exposed to twenty combined conditions involving four hotter temperature levels and five noise levels in summer, and twenty-one of them were also exposed to combined four lower temperature levels and similar five nose levels in winter. The subjects reported their sensations regarding each combined condition. The equi-comfort and equi-acceptance charts for respective seasons and exposure periods were derived on the basis of the results. The contour lines of the equal universal comfort and acceptance sensations, respectively, were drawn in the charts with temperature and noise levels on the axes. These two kinds of charts can indicate the combined conditions which would be acceptable but not comfortable, as well as the grades of human comfortableness and acceptableness by themselves within this experimental condition.%どのような生活環境が人間にとって安全•健康•快適かについて、今日まで数多の研究成果が蓄積されてきた。健康で快適な生活のための環境規準（建築基準法や建築物術生法、環境基本法など）や快適規準（ASHRAE StandardやISOなど）もこれらの知見に基づいている。しかしいずれの規準も、例えば室温17～28℃騷音レべル55dB(A)以下というように、個々の環境要素別に示されている。
