Abstract

This paper deals with the design of transaural systems in usual rooms, whose response has a strong influence on sound reproduction. The paper proposes to select configurations for the best perceptual rendering. However, realistic perceptive experiments cannot deal with the many possible room and loudspeaker configurations. Therefore, the authors propose to assess them using objective scores that are extrapolated from the results of perceptive tests assessing a suitable selection of rooms and loudspeaker configurations. This extrapolation then allows comparison of a much larger set of combinations, leading to the conclusion that close-to-ears configurations allow reduction of the room influence, leading to a good perceived fidelity---even inside usual rooms. Closer loudspeakers are, however, likely to be more sensitive to listener position, so the robustness of loudspeaker configurations to listenermisplacement were investigated. A suitable objective score, again based on a perceptive test, led to the surprising conclusion that some close-to-ears configurations are also robust to listener position.
