3次元音場再現システムでのコンテンツ選択における指針の提案

抄録

It has been reported that the "sense of presence" is affected by the reproduced sound contents in auditory virtual environments. The selection of the reproduced sound contents is important for the evaluation of the auditory virtual systems appropriately. This paper describes our trials to classify the sound contents depending on experienced realities in a 3-D reproduction sound system. After participants listened to the sound contents, they were asked to evaluate the contents by twelve evaluation points. Principle component analysis and cluster analysis revealed that sound reproduced contents were classified into three categories : music, voices, and moving sound objects. These categories are linked to different elements of sense of presence. From these results, we proposed that three kinds of the reproduced contents are needed for the evaluation of auditory virtual systems.
