Abstract
The paper presents the distance threshold for complex virtual sounds
localization in dependence of the time interval. The method of measurement
was a forced-choice, three-down one-up staircase. The sound is a complex
record of a click sound of 47 ms at 44.1 kHz measured by using a maximum
length binary sequence in an anechoic chamber. The azimuth of the experimental
is 0, at the center of the human head where the ITD = 0, varying just
the intensity. The investigation reported that the lowest distance thresholds
of 0.06 m occurred for high inter click intervals at 200 ms¿300ms. At lower
ICIs, the distance threshold increases considerably. The experimental was
carried out with the objective to find the distance threshold and time interval
for implementing the data for a navigation device for blind people.
