Title

Adjustment of direct-to-reverberant-energy-ratio and the just-noticable-difference

Abstract
The adjustment of the direct-to-reverberant-energy-ratio (DRR) within a binaural synthesis system is assessed in a listening test. The DRR is changed until the assessors perceive congruence between the synthesized and listening room. The results of the experiment are relevant to apply adaption methods on binaural synthesis to increase plausibility involving context dependent quality parameters like room divergences between the synthesized auditory scene and the listening environment. Furthermore, a discussion is aspired about the relationship between just-noticeable-difference in DRR perception and inter-quartile-distances of the adjusted DRRs.
