"The QESTRAL model is a perceptual model that aims to predict changes to 
spatial quality of service between a reference system and an impaired 
version of the reference system. To achieve this, the model required 
calibration using perceptual data from human listeners. This paper 
describes the development, implementation and outcomes of a series of 
listening experiments designed to investigate the spatial quality 
impairment of 40 processes. Assessments were made using a multi-stimulus 
test paradigm with a label-free scale, where only the scale polarity is 
indicated. The tests were performed at two listening positions, using 
experienced listeners. Results from these calibration experiments are 
presented. A preliminary study on the process of selecting of stimuli is 
also discussed."
