Differences between sound sources in effects of combined thermal-acoustic environment on comfort.

The combined thermal - acoustic environmental effects and the boundaries of these effects on comfort were of significant importance in the development of subjective perception prediction models. Previous studies on this topic mainly focused on either only one sound source or overall data, and the differences related to sound sources were not fully considered. This study aimed to compare and analyse the differences between positive sounds (music) and negative sounds (fan noise) in the combined effects of thermal - acoustic environment in a laboratory setting. The results showed that the boundaries varied among different sound sources. The boundaries of thermal comfort for music were a little stricter than those for fan noise.
