Why can you hear a difference between pouring hot and cold water? An investigation of temperature dependence in psychoacoustics

摘要

Studies have shown that listeners can distinguish between hot and cold water being poured based solely on sonic properties, yet the cause of this is unknown. This acoustic perception of temperature is an interesting aspect of multisensory perception and integration. In this paper, a series of experiments were performed to investigate the characteristics of auditory information when water is poured at different temperatures into various containers. Based on the results, it attempts to find physical and psychoacoustic explanations for the phenomenon.
