Acoustic Support System
This early patent for an Acoustic Support System for hearing aids addresses a big and growing market. It describes a technology to add harmonic waves to the basic frequencies to active and train hearing abilities; and enrich and ease the sound for a better understanding. The patent is granted only in Germany, but due to the size of the German market and the origin of the key market Players (esp. producers of hearing aids) from Germany or neighbouring countries, it indirectly targets the world market.
The described Acoustic Support System targets users that cannot hear specific frequencies. These disabilities are normally addressed with electro-acoustical amplifiers by increasing the relevant frequencies. The described technology proposes that the hearing aid (a) activate and trains the hearing ability by adding harmonic waves that stimulate the hearing sense; and (b) supports the hearing abilities by complementing the basic frequencies with related harmonic waves. The user "learns" to relate the harmonic waves to the disabled frequencies and hereby decodes the sound more clearly.
3. Development Stage
The inventors successfully build a prototype in 1997 but did not follow up with a commercial product.
4. Market / Opportunity
Only a few big companies control the world market, whereof Siemens (D) is markel leader with 23% followed by Phonak (CH) and William Demant/Otikon (DK) with 22% market share each. Resound (DK) is #4 addressing 13% of the world market. All four companies have a very strong position in the German market - with a total value of approx. 300 mUSD - and, cumulatively, catch >80% of the hearing aid sales. The technology to add harmonic waves to increase the hearing ability is known and used in commercially available hearing aids. Due to the increase in the proportion of elderly people, the market for hearing aids will continue to grow significantly. As the German market is one of the most important markets worldwide for hearing aids and the most relevant players are located and partially have manufacturing sites in Germany or one of the neighbouring countries, the patent has a significant value for the world market, even if just a German patent is granted.
The described Acoustic Support System, respectively this early patent, could be interesting for any producer of hearing aids or an IP-holding-company seeking "licensing out” opportunities.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
Physicists in Garching observe novel quantum effect that limits the number of emitted photons.
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
