CONGRESO DISTANCE THRESHOLD ON VIRTUAL SOUND LOCALIZATION ON HUMANS

Abstract

The paper presents the distance threshold for complex virtual sounds localization in dependence of the Inter Click Interval. The method of measurement was a forced-choice, threedown one-up staircase. The sound is a complex record of a click sound of 47ms at 44,1kHz. The azimuth is at 0°, at the center of the human head where the ITD=0 varying the intensity and frecuency. The investigation reported that the lowest distance thresholds of 0,06m occurred for high Inter Click Intervals at 200-300ms. At lower ICIs the distance threshold increases considerably.
