“…Besides the cases that can be found in the animal literature (Skals, Anderson, Kanneworff, Löftstedt, & Surlykke, 2005), the main example would come from a correlation between smell and sound intensity when their common source gets closer or farther from the perceiver (see Wright & Thomson, 2005). This relation gets expressed in crossmodal correspondences between olfaction and audition: Sounds of high volume are associated with a high concentration of an odor, whereas a low volume is associated with a low concentration of an odor (Persson, 2011).…”
