In this paper, we address the problem of subjectively evaluating the spatial quality of a given sound event, or auditory scene, produced using array of loudspeakers and various spatial reproduction methods. In particular, we focus our attention on recently introduced numerical methods that are capable of addressing some of the limitations of analytical methods of sound field reproduction. The evaluation is performed through a novel listening test methodology derived from a common multiple stimuli test for which we provide the implementation details on its adaptation to spatial audio evaluation. The testing is done in both anechoic and non-anechoic conditions, and the results obtained are statistically significant and clearly outline some of the benefits and limitations of the presented methods.
