Nothing but first-class seats at the movies

29.06.2006
Visitors to the 4D cinema in the grounds of the Bavaria Film Studios can plunge into a completely new kind of movie experience. Not only are the images real enough to touch – as is usual in 3D movie theaters – but the sound, too, gives viewers the feeling of being in the thick of events.

Against the backdrop of an abandoned mine, the wind drives bales of dry tumbleweed across the seats of the movie theater. A thunderclap makes the audience flinch – the thunderstorm is right over their heads. Then down comes the rain, so close that they can almost feel it. A hissing rattlesnake darts out of an old tipper truck and turns into the ghost of the old mine keeper, who takes the visitors on a helter-skelter journey through the haunted mine.

The illusion is created by state-of-the-art video and audio engineering methods. The IOSONO sound system developed at the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau ensures perfect acoustic reproduction in all seats – regardless whether a viewer is sitting at the front or the back, at the side or in the middle. Until now, only a few seats offered perfect surround sound. The traditional multi-channel system works by cleverly mixing the sound signals coming from right and left, back and front, but the desired surround-sound effect is only achieved at a central point in the room, the so-called "sweet spot".

IOSONO no longer has such a sweet spot, or rather, the sweet spot is everywhere. A ring of loudspeakers is positioned right round the movie theater. The acoustic signals emitted by the speakers overlap and interact in such a way as to create the perfect surround sound experience in every seat. "The IOSONO technology makes sound waves spread evenly across the room, rather like the ripples you create when you throw a pebble into a pond," explains Dr. Sandra Brix of the IDMT, a member of the IOSONO development team. A "synthetic wave field" is generated by superimposing the sound waves from all 432 loudspeakers.

Although calculated by several computers, this wave field conveys a realistic impression of natural sound. Nothing is left to chance: The sound engineer can place a virtual sound source at any point in the room, and the software ensures that the loudspeakers produce the corresponding acoustic signals – such as the rattlesnake, which appears poised to strike the viewer, regardless of whether he or she is sitting in the front or the back row.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
