Abstract

To clarify the effects of the temporal structure of sound and motion picture on the impression of audio-visual contents, the impression of various kinds of audio-visual combinations was measured by a semantic differential method. The experimental variables of audio-visual stimuli are the speed of the motion picture, the tempo of the auditory stimulus, and the temporal relationship between the visual and auditory accents. The synchronization of visual and auditory accents raises the subjective congruency of audio-visual contents. The matching of auditory tempo and visual speed also affects the subjective congruency. The subjective impact is stronger as the speed of motion picture becomes faster. The accents synchronization also contributes to the strong impact of the audio-visual contents. The subjective lightness is determined by the musical tempo. A faster music causes a lighter impression of audio-visual contents. The subjective complexity is based on imbalance of the visual and auditory speed. The mismatching of musical tempo and visual speed evokes a complex feeling of audio-visual contents.
