Perceptual differences between sound reproduction systems with multiple spatial dimensions have been investigated. Two blind studies were performed using system configurations involving 1-D, 2-D, and 3-D loudspeaker arrays. Various types of source material used, ranging from urban soundscapes to musical passages. Experiment I consisted in collecting subjects’ perceptions a free-response format identify relevant criteria for multi-dimensional complex auditory scenes by means linguistic analysis. II utilized both free response scale judgments seven parameters derived form I. Results indicated strong correlation the (sound scene) subjective evaluation parameters, making notion an “optimal” method difficult arbitrary material.
