Abstract
The purposes of this study are to investigate effects of thermal and acoustic comfort on overall indoor environmental comfort under time-varying short-term noise exposure, and to identify cross-modal perception between thermal and acoustic environments. Subjective assessment was conducted in an indoor environmental chamber with an environmental control system. Fifty four participants were exposed to three indoor temperatures (18, 24 and 30℃) and four levels of traffic noise (45, 50, 55 and 60dBA). Each traffic noise stimulus was presented for 25 seconds. Thermal comfort, acoustic comfort and overall indoor environmental comfort were evaluated in each combined environmental condition. Acoustic comfort affected indoor environmental comfort greater than thermal comfort with short-term noise exposure. At thermoneutrality, acoustic comfort increased. Gender difference was found only in acoustic comfort in the overall data analysis.
