Outline of Final Research Achievements |
It is difficult to evaluate a difference between real sound source and virtual sound image only by sound localization test. In this study, we focus on sense of presence of a virtual sound image as an indicator to evaluate Virtual Auditory Display. We examined image of the word “presence of a sound source” and carried out factor analysis. Also we prepared an experimental environment that listeners listen to sounds both from real speakers and from VAD system with headphones based on HRTFs (Head-Related Transfer Functions). Listeners answered perceived direction, vraisemblance, and presence of a sound source.
