Description

The purpose of this study is to quantitatively determine the combined effect of lower temperature and noise on the human psychological responses and to propose a new environmental index for expression of the combined effect of them. In this study, twenty-two male students were exposed to the combined twenty conditions of operative temperatures (19, 22, 25, 28°C) and noise levels (46.6 dB (A): air-conditioning noise; 58.5, 72.9, 79.9, 95.5 dB (A): traffic noise). The subjects reported their sensation votes for each combined condition using the linear unipolar scales. As a result, thermal condition affects noisy sensation and auditory condition affects hot sensation significantly in addition to the effect of thermal/auditory condition on hot/noisy sensation. Consequently, both of temperature and noise affect the universal comfort and discomfort sensation. Equi-comfort and equi-discomfort charts constituted with the thermal and auditory comfort/discomfort sensation votes, and with the operative temperature and noise level were proposed to quantitatively evaluate the combined effect of thermal and auditory environment. They are valid as new comfort indices within this experimental conditions.<br>
