Distance perception of recorded instruments in virtual monitoring environments

Fotis Georgiou , Bruno Fazenda

Accurate distance perception in virtual audio systems is very important and during the last decade there has been an increased interest in this research area. In this research paper we investigate the effects of the different types of music stimulus on the perception of distance and how well modelled BRIRs simulate distance perception compared to measured ones. The BRIR were measured on a small and medium sized room. BRIR were generated for identical conditions modelled through a hybrid image source model with exponentially decaying noise for the simulation of late reverberation. Two subjective tests were conducted. In the first five musical instrument samples were convolved with the measured and modelled BRIR in order to observe their effect on distance perception. On the second test, the efficiency of the modelled BRIR was investigated by doing a direct comparison with the measured BRIR.
