3D sound intensity measurement of 1241 sound objects rendered by Dolby Atmos on fine panning grids was carried out by using a Virtual Source Visualizer (VSV). The obtained sound localizations were visualized as a 3D panning map. To evaluate properties of reproduced sound fields for several kinds of rendering systems in various rooms, the authors have previously carried out VSV measurements of sound objects on some main panning positions. The results roughly illustrated each acoustic feature of rendered sound fields. This measurement was carried out to find out the relationship between 3D panner’s indications and physical sound localizations on finer scale. The visualized sound localizations formed “3D panning position map” that clearly shows the relationship between them.
