This paper presents a subjective study of spatial impression attributes and their perception in a 6 Degree-Of-Freedom context. For a plausible reproduction of virtual acoustics in a VR/AR/MR it is important to understand how different spatial impression attributes change perceptually for different positions in the room and for different head orientations. An elicitation test was carried out using the Repertory Grid Technique (RGT), in a virtual environment, using Binaural Room Impulse Responses (BRIRs) recorded in a reverberant concert hall. Results show an agreement with current literature and a previous elicitation test. New attributes such as “echo/reverb directionality” were found to also be perceived by participants, as a result of the different listening positions and head orientations.
