Influence of visual information on sound evaluation in auditorium

When hearing music in an auditorium, audience is provided with aural information and visual information at the same time. Visual and auditory sense sometimes interact with each other so that the auditory sense is considered to have some influence on sound evaluation made by audience. The purpose of this study is to reveal an influence of visual information obtained in audience seats in a hall on subjective evaluation. We investigated the relationship between sound evaluation and whether a musical performance video as visual stimulus is provided or not, and between the sound evaluation and evaluation concerning the space at certain position in the audience seats. As a result, it was revealed that visual information gave statistically significant influence on sound evaluation.

Possibility of sound environmental design by introducing wave sound into the indoor space

The purpose of this study is to develop the means of designing sound environment of waterfront area. As one of the means of improving sound environment in the campus space of our university, introducing wave sound from the adjoining seashore into campus area has been proposed and its feasibility have been studied. But wave sound reaches 300 m inland at most and cannot be listened in the most of campus area outdoor. So we plan to introduce wave sound by picking up through microphone and steaming over the campus LAN. In this report, if wave sound is streamed and broadcasted to indoor spaces, the influence of wave sound as background/masking noise on the mental state of users in the space is studied. The samples of various wave sound recorded at seashore near the campus are broadcasted in indoor spaces, such as cafeteria, learning spaces, etc. And subjects are asked to answer the questionnaire about preference and subjective impression for indoor environment. The results show that wave sound is almost accept...

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

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 a...
