Seeing Sounds, Hearing Shapes: a gamified study to evaluate sound-sketches
share
Sound-shape associations, a subset of cross-modal associations between the auditory and visual domain, have been studied mainly in the context of matching a set of purposefully crafted shapes to sounds. Recent studies have explored how humans represent sound through free-form sketching and how a graphical sketch input could be used for sound production. In this paper, the potential of communicating sound characteristics through these free-form sketches is investigated in a gamified study that was conducted with eighty-two participants at two online exhibition events. The results show that participants managed to recognise sounds at a higher rate than the random baseline would suggest, however it appeared difficult to visually encode nuanced timbral differences.
