The relationship between panning positions and positions of generated phantom sound images is one of the important factors for creating immersive sound content. In order to clarify it, the authors conducted a sound intensity measurement at a Dolby Atmos compliant mixing room, then 1241 positions of sound objects which are generated in the studio are detected. By analyzing detected objects` positions and their corresponding positions of an Atmos panner, “3D panning map” of the studio is obtained. As a result of numerical analysis of the map, “3D panning table” is also obtained. The map and table provide physically proper panning positions, X, Y, Z values of the panner, on desired positions in which a mixing engineer intends to place a sound object. The proposed tool "3D panning table" contributes to production work of creating immersive sound content efficiently.
