3D Directivity Measurement of Immersive Audio Systems

3D audio and immersive sound is pushing the listeners experience to a new level. To reproduce spatial sound the complexity of the sound systems have increased a lot compared to a standard Hifi-Stereo system. For example, many loudspeakers are distributed in the listening room. Other methods use complex centralized sound systems with many transducers and large dimensions (e.g. line arrays, pla-nar arrays, sound panel). These devices can shape very distinct beams and include controlled reflec-tions from the room boundaries to create an immersive sound experience. The control algorithm of the sound devices requires directivity data of the individual transducers with very accurate phase in-formation, which cannot be fulfilled by performing traditional far field measurements. The presenta-tion will give an overview on state of the art directivity measurements that comply with the high re-quirements and determine comprehensive data of near- and far-field.
