Vertical Loudspeaker Arrangement for Reproducing Spatially Uniform Sound

Document Thumbnail

It was recently recognized that the loudspeaker arrangement of multichannel sound systems can be vertically expanded to improve the spatial impression. This paper discusses the relationship between the vertical interval between loudspeakers placed in a semicircle above ear height and the impression of spatially uniform sound, as part of a study of three-dimensional multichannel sound systems. In total, 24 listeners evaluated the spatial uniformity of white noise reproduced by loudspeakers arranged in vertical semicircles at equal intervals of 15°, 30°, 45°, 60°, 90° or 180°, and with azimuthal angles of 0°, 45°, or 90°. Loudspeakers arranged with vertical intervals that were less than 45° were found to reproduce spatially uniform sound for all of the azimuthal angles tested.
