Work by the animation filmmaker Samantha Moore and the synesthesia researcher Jamie Ward carried out as part of their joint project Synaesthesia and Sound supplies interesting views of what is referred to as colored hearing.

In a first step, the visual perceptions of five individual synesthetes that were elicited by twenty different sounds were animated and combined in the short film Seeing Sound. The color and orientation of these visualizations were then modified and subsequently given, together with the original versions, to non-synesthetes to evaluate.^[1] It appeared that sound and image were perceived as more aesthetic in combination than when they were shown isolated, and that visualizations created by synesthetes were perceived as more adequate in their original colors than in modified colors.^[2] Synesthetic visualizations of sounds are also presented as animations in the documentary film An Eyeful of Sound. The film attempts to exemplify the perceptual reality of colored hearing to the audience where it illustrates individual synesthetic perceptions; while it also presents personal background stories of synesthetes and the way that synesthesia has had an influence on their characters and their everyday lives. At the same time, the film communicates scientific insight on synesthesia and affords an opportunity to relate to this special kind of perception on an auditory and visual level.
