N2 - The overall aim of this research is to develop a high-presence sound system for an emergency drill simulator using a virtual reality display system that runs on a personal computer. Previous studies have reported systems that provide high-presence sound, but these systems needed powerful computers to perform the required processing. With our proposed method, the processing is reduced by using a discontinuous moving sound image given by discrete coordinates. We evaluated the synchronization of the moving sound image by conducting an experiment in which pairs of stimuli were compared. In the experiment, moving sound images with different speeds were compared in order to obtain a threshold for the number of discrete coordinates of the moving sound image to realize high presence. We analyzed the relationship between the evaluations and the speed using a paired comparison method. The results showed that the evaluation of the realism depended on the speed of the sound image.
