Spatial impression is a widely researched topic in concert hall acoustics and spatial audio display. In order to provide the listener with plausible spatial impression in virtual and augmented reality applications, especially in the 6 Degrees of Freedom (6DOF) context, it is first important to understand how humans perceive various acoustical cues from different listening perspectives in a real space. This paper presents a fundamental subjective study conducted on the perception of spatial impression for multiple listener positions and orientations. An in-situ elicitation test was carried out using the repertory grid technique in a reverberant concert hall. Cluster analysis revealed a number of conventional spatial attributes such as source width, environmental width and envelopment. However, reverb directionality and echo perception were also found to be salient spatial properties associated with changes in the listener's position and head orientation.
