Abstract
The interaction between thermal and acoustic factors has been demonstrated to influence indoor comfort perceptions significantly. However, the boundaries within which these factors collectively affect comfort perceptions and their predictive efficacy, which directly determine the effectiveness of combined thermal-acoustic environmental effects, have not been thoroughly investigated and represent a key issue that request urgent attention in this field. To address this gap, an experiment was conducted in an environmental chamber, with six common indoor temperature levels (18, 20, 22, 24, 26, and 28 °C) and ten sound pressure levels (35, 40, 45, 50, 55, 60, 65, 70, 75, and 80 dBA) being selected in this study. The results revealed that when the sound pressure level exceeded 71.3 dBA, temperature had no significant effect on overall comfort; when the temperature dropped below 18.5 °C, sound pressure level did not significantly influence overall comfort. The combined effects of thermal-acoustic environments on comfort existed within the boundaries defined by certain temperature and sound pressure levels. Additionally, in highly comfortable or adverse environments, the predictive performance of thermal-acoustic environments for comfort perception was poorer. This decline in predictive accuracy may be attributed to greater variability in comfort perception influenced by individual differences or other factors in these conditions. This study contributes to a deeper understanding of the mechanisms underlying thermal-acoustic environmental effects and is significant for enhancing the precision of comfort perception predictions and further developing comprehensive models of multiple factors.
