Effect of visual information on subjective impression for sound field in architectural space

Abstract

In architectural and urban space, we are always exposed to multimodal stimuli of visual information and sound fields in various scenes of everyday life. The purpose of this study is to clarify relationship of subjective impression of vision and auditory, and acquire knowledge which contributes to architectural design or acoustic design. In this report, two following experiments are carried out in which subjects are presented with sound fields by real time convolution as auditory stimuli and panoramic VR images of 360 interactive views of interior as visual stimuli. 1.Comparison between subjective responses for single or multi modal presentations of visual and auditory stimuli from various architectural spaces. 2.Comparison between subjective responses for various combinations of multi modal presentations of visual and auditory stimuli from various architectural spaces. Analysis for results of these experiments clarify the influence of visual information upon the subjective impression for sound field and mutual relationship between subjective impression of vision and auditory of interior of buildings. It is already found that visual information significantly effects subjective impression for sound field by experiment 1, and the details of relationship between elements of visual information and parameters of sound field will be clarified by experiment 2.
