Acoustic digital twin for Salzburg festival
Siemens is developing a digital twin to simulate acoustics for the first time for the Großes Festspielhaus festival in Salzburg, Germany.
Siemens has developed a digital twin especially for large event spaces to realistically reproduce and simulate very precisely a building’s acoustics and structure. The simulation can measure the echo and reverberation of a sound in a 3D model and simulate how sound waves propagate in a room.
The Sound of Science application will be used for the first time in the Großes Festspielhaus – the Large Festival Hall at the Salzburg Festival, and Siemens is planning to digitally simulate further spaces, including concert halls in Germany and England.
The digital twin allows event organizers to virtually explore how acoustics change in different spatial configurations – for example, how adding acoustic panels affects the listening experience – in order to select the optimal acoustic scenario.
Orchestral formations on the stage can also be tested and arranged in advance – before a single note is heard in the real world.
“With Sound of Science, we’re designing the future. Digital twins are not only transforming the everyday for many companies but are also creating new opportunities for the cultural and creative industries,” said Prof. Dr. Stephan Frucht, Artistic Director of the Siemens Arts Program. “In the future, we’ll be able to plan stage productions better and even simulate them acoustically in advance. We’re delighted to have the Salzburg Festival at our side as a long-standing partner, who recognizes the opportunities such innovations offer.”
Siemens will make the Sound of Science app available to selected partners from the cultural world free of charge as a demonstration application. There are currently no plans to market the application but Siemens is selling its simulation tools in Simcenter.
For Sound of Science, Simcenter uses a combination of impulse response measurements and ray tracing for the 3D modeling of each event space. These methods can measure the echo and reverberation of a sound and simulate how sound waves propagate in a room. Depending on the material, reflections of sound waves behave differently. Those that bounce off a concrete wall react differently from those that hit a carpet or reach the ear directly. As a result, the simulation can reproduce the individual sound signature of each event space.

Siemens has been working closely with the Salzburg Festival for around 30 years. Since 1999, the company has also been the festival’s main sponsor. Since 2002, the Siemens Festival Nights have been held on Kapitelplatz square during the Salzburg Festival.
