Siemens achieved the highest award honoring technology and innovation in Germany for the fourth time - more often than any other company. Joachim Gauck, President of the Federal Republic of Germany, awarded the prize on November 28th for an innovation which makes it possible for patients with hearing loss to hear stereophonically again.
This binaural technology is based on the sound perception of both ears. It enables state-of-the-art hearing aids to remedy a significant component of hearing loss.
The binaural technology is modeled after the natural hearing function of a healthy individual: Analogous to stereo vision, hearing can be stereophonic only through the interaction of both ears. This requires patients with hearing loss to have the hearing aids of their right and their left ear interconnected. Eight years ago Siemens researchers managed for the first time to create this interconnection - with what was then the world's smallest wireless system.
This makes it possible for both hearing aids to interchange and recalculate large data volumes and to adapt synchronically to the momentary auditory situation. The interaction creates an authentic ambient sound quality. The individual hearing aids of the left and right ear interchange wireless information and, for example, adjust the volume automatically.
The principal challenges in developing new hearing aids are to optimize voice transmission while presenting a homogenous ambient stereophonic sound. Ongoing development of binaural hearing systems with integrated wireless technology will target further optimization of the sound pattern. The intelligent devices of the future will automatically identify more and more hearing situations and automatically react to them.
The German Future Prize was established in 1997 by former President Roman Herzog. In addition to the research achievement itself, the most important selection criteria include patentability and marketability. Siemens researchers have been nominated for the Prize eight times and claimed victory in 2004, 2005 and 2007.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
