The contribution presents a study that investigates the perception of spatial audio reproduced by a binaural synthesis system. The quality features externalization and room congruence are measured within a listening test. Former studies imply that especially externalization is decreased if acoustic divergence between the synthesized and listening room exists. Other studies show that the adjustment of the Direct-to-Reverberant- Energy-Ratio (DRR) can increase the perceived congruence between synthesized and listening room. Within this experiment test persons are able to adjust the DRR of the synthesis until perceptional congruence between the synthesis and the internal reference concerning the listening room occurs. The ratings show that the test persons are able to adjust DRR of the listening room and therefore externalization increases.
