Floating in Space – with Fraunhofer 3D Sound at Zeiss Planetarium Jena

01.11.2011
From now on, visitors of the Zeiss Planetarium in Jena can go on an acoustic and visual journey like no man went before: With "SpatialSound Wave" the scientists of the Ilmenau Fraunhofer Institute for Digital Media Technology IDMT create an outstanding spatial sound event in a dome theater.

It is the first fixed installation of this Fraunhofer 3D sound system. The combination with the newly installed full-dome projection system of Carl Zeiss AG creates impressive 3D worlds for eyes and ears. On November 3rd, 2011, the innovative image and sound concept of the Zeiss Planetarium is going to be introduced to the public.

The Fraunhofer sound solution creates a naturally immersive sound environment absorbing the audience into a world of musical-acoustic effects. The listeners experience the scenes in outstanding quality on every seat. SpatialSound Wave is based on Wave Field Synthesis. With the integration of the innovative sound system in Jena it is the first time such a fixed installation like this has been set up in a planetarium.

For the audience in the Jena dome theater, this Fraunhofer technology opens up totally new opportunities: Apart from a natural nightlife sound scenery, the audience experiences most diversified music highlights and thrilling audio drama. René Rodigast, responsible for the project at Fraunhofer IDMT, describes the advantages of this new 3D audio system: "Our SpatialSound Wave system could be easily integrated in the existing sound solutions of the planetarium. In order to do so, 60 loudspeakers that are controlled by our audio system, have been integrated inside the dome as well as horizontally around the audience. This way, sound sources – a speaker, FX sounds or musical effects – can be positioned freely in the dome theater and arranged as 3D audio shows".

In addition to SpatialSound Wave, this planetarium also uses state-of-the-art projection technology by Carl Zeiss AG. Their digital full-dome projection system "powerdome®VELVET" featuring highest contrast, allows video projection of any content across the whole planetarium dome. It completes the classic, opto-mechanical star projection technology of the "Universarium" projector. In addition to purely astronomic presentations, the digital ZEISS technology allows crisp video projections with 3D effects on a pitch-black background.

The three-dimensional experience for eyes and ears is created by an interface between the SpatialSound Wave and the powerdome®VELVET systems. This way, audio and video content is synchronized. On a projection area of 900sqm, the audience goes on an acoustic and visual space flight.

"We are proud to be one of the most state-of-the-art planetariums worldwide – thanks to innovative technologies from Thuringia. The novel effects enrich our education and entertainment program and make discovering the stars a real multimedia experience", says Jürgen Hellwig, Managing Director of STERNEVENT GmbH, the operating company of the Zeiss Planetarium in Jena.

The new concept will be introduced on November 3rd, 2011, at 11 a.m. on a press conference in the Zeiss Planetarium Jena. From 7 p.m., the technical novelties will be presented in an evening ceremony.

Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau conducts applied research in the field of digital media and works on leading projects and topics in the field of audio-visual applications.

Besides sound solutions for home and professional users (e.g. IOSONO® Wave Field Synthesis technology) software technologies for analysis and characterization of multimedia content as well as audio-visual applications for medical engineering are being developed. Furthermore interactive AV applications for entertainment and knowledge management and the design of architectures for digital online-distribution are in the institute’s research focus.

The Fraunhofer IDMT realizes innovative scientific results through prototypes and applicable solutions which come up to customer and market requirements in close cooperation with partners in economy, culture and science.

Since 2008, Fraunhofer IDMT has two new branch labs. The department Children’s Media, based in Erfurt, works on the development of innovative computer based program and edutainment formats for children and adolescents. The new project group Hearing, Speech and Audio Technology, based in Oldenburg, researches topics of audio system technology concerning the fields of health, transportation, multimedia and telecommunication.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
