Abstract (in Japanese) (See Japanese page) 
(in English) In real world, we hear various sounds including ambient sounds which, for example, are radiated from ventilation systems. However, most of currently developed virtual auditory displays can reproduce point sources which are attributable to specific objects’ location, but cannot such ambient sounds. This results in an unnatural sound space, which leads to a degradation of the presented sound space quality. In this paper, we propose a rendering method of ambient sounds, and report the results of investigation of effects of rendered ambient sounds on a perception of sound space.
