"The QESTRAL model is a perceptual model that aims to predict changes to 
spatial quality of service (SQoS) between the soundfield reproduced by a 
reference system and that of an impaired version of the reference system. 
To calibrate the model subjective data collected from listening tests is 
required. The QESTRAL model is designed to be format independent and 
therefore it relies on acoustical measurements of the reproduced soundfield 
derived using probe signals (or test signals). The measurements are used to 
create a series of perceptually motivated metrics, which are then fitted to 
the subjective data using a statistical model. 
This paper has two parts. The first part describes the implementation and 
results of a listening experiment designed to investigate changes to 
spatial quality. The second part, presents results from a calibration and 
forecasts prediction power (via cross-validation) of the QESTRAL model."
