Audio-visual Mutual Effect of Spatial Impression in Architectural Space
* Presenting author
The purpose of this study is to clarify the influence of visual information on subjective impression for room sound field. Authors have carried out subjective experiments on it using room impulse response signal as auditory stimulus and interior panorama picture as visual stimulus, and found that reverberance/clarity for room sound field is affected by information sensible from room volume, dimensions, geometry or finishing etc. And then in this report, experiments about visual effect on spatial impression (ASW and LEV) in auditorium were conducted to clarify the influence of room volume, size or geometry on them. Auditory stimuli were made in anechoic chamber by binaural microphone recording under the conditions that directions of early reflections and late reverberation were varied, and were presented to subjects through headphone. Visual stimuli were made of panorama pictures captured around room interior or drawn by CAD, and were presented by HMD. ASW and LEV were measured under single-mode or multi-mode presentation of visual /auditory stimuli, and mutual effect of visual and auditory sense were examined in architectural space.
