Abstract: Three studios of similar outer-shell dimensions, with varying acoustic treatments and absorptivity, were evaluated via both recorded and simulated binaural stimuli for 22.2- and 2-channel playback. A series of analysis, including acoustic modelling in CATT-Acoustic and subjective evaluation, was conducted to test whether the 22.2-channel playback preserved common perceptual impressions regardless of room-dependent physical characteristics. Results from multidimensional scaling (MDS) indicated that listeners used one perceptual dimension for differentiating between reproduction format, and others for physical room characteristics. Clarity and early decay time measured in the three studios illustrated a similar pattern when scaled from 2- to 22.2-channel reproduced sound fields. Subjective evaluation revealed a tendency to preserve inherent perceptual characteristics of 22.2-channel playback in spite of different playback conditions.
