THREE DIMENSIONAL ENVIRONMENT LOCALIZATION THROUGH VIRTUAL SOUND EXPERIMENTAL

Abstract

[EN] The paper deal with the development of an experimental for 32 virtual simultaneous sound localization. The experimental is based on the development of two interfaces: the graphic virtual environment that includes different images as plane geometric figures and three dimensional geometric figures and daily figures as trees, etc. and the virtual acoustic sounds. The experimental treats to study simultaneous sound sources localization through headphones, as the study of the psychoacoustic characteristics on simultaneous sound localization. For the experimental was analysed the time dependence and intensity and frequency dependence as time thresholds. The virtual sounds are generated in real time in elevation, direction and depth. Previous results demonstrate that the humans are able to perceive simultaneous sounds and to localize them in the environment.
