Prolight & Sound Frankfurt 2020 cancelled

KLIPPEL at Prolight & Sound


Prolight + Sound Frankfurt 2020 cancelled

On 12 March, the Hessian Ministry for Social Affairs and Integration issued general decrees prohibiting large-scale events expected to attract more than 1,000 visitors due to the background of the rapid spread of SARS CoV-2 infections. At the present time, it cannot be assumed that the current situation will have changed by the time the postponed event was to have been held. Therefore, Messe Frankfurt has decided to cancel the event.

Prolight + Sound 2021 will be held from 13. - 16. April. More information on the official Prolight+Sound website

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.
