Abstract
With the rapid spread of social media, it is currently common to see various heavy rain videos filmed by individuals. However, it remains unclear how the viewers feel about flood-risk. Using rain videos with different audiovisual conditions, we examined whether audiovisual stimuli affect people's perception of rainfall. The results revealed that the loudness of sound, height of sound, brightness of the image, and size of the screen each had an effect on rain perception; of which, the loudness of the sound had the greatest effect. In addition, we found that women perceived rainfall more strongly than men, and that younger people were more sensitive to stimuli. Our findings enable discussions of the reproducibility of rain and sensory characteristics of rain perceived through the viewing of rain videos.
