Abstract: This paper presents a subjective study conducted on the perception of salientauditory attributes depending on the listener s position and head orientationsin an enclosed space. Two elicitation experiments were carried out using theRepertory Grid Technique; in-situ and laboratory experiments aimed to identifyperceptual attributes among ten different combinations of the listener spositions and head orientations in a concert hall. Results revealed that,between the in-situ and laboratory experiments, the listening positions andhead orientations were clustered identically. Ten salient perceptual attributeswere identified from the data obtained from the laboratory experiment. Whilstthese included conventional attributes such as ASW (apparent source width) andLEV (listener envelopment), new attributes such as PRL (perceived reverbloudness), ARW (apparent reverb width) and Reverb Direction were identified,and they are hypothesised to be sub-attributes of LEV (listener envelopment).Timbral characteristics such as Reverb Brightness and Echo Brightness were alsoidentified as salient attributes, which are considered to potentiallycontribute to the overall sound clarity.
