New Dutch invention: Varibel, the glasses that hear

07.04.2006


These hearing-glasses are called ’Varibel’ and offer older people the chance to stay active longer - free from the aesthetically unpleasing and technologically limited traditional hearing aids. In each leg of the glass’ frame there is a row of four tiny, interconnected microphones, which selectively intensify the sounds that come from the front, while dampening the surrounding noise. The result is a directional sensitivity of +8.2 dB. In comparison, regular hearing aids have a maximum sensitivity of +4 dB.

Today a new hearing aid in the form of a pair of glasses was unveiled. These hearing-glasses are called ’Varibel’ and offer older people the chance to stay active longer - free from the aesthetically unpleasing and technologically limited traditional hearing aids. Delft University of Technology in the Netherlands originally developed the hearing-glasses. Varibel developed these glasses into a consumer product in partnership with Philips, Frame Holland, the design agencies MMID and Verhoeven, and others.

Approximately 1,265,000 people in the Netherlands over the age of 60 are hearing impaired. Of these, half 22% (or around 275,000 people) use a hearing aid, but it is not always possible to hear others well if there is surrounding noise. Many hearing aids intensify sounds from all directions. The result is that people hear noise, but not the people they are speaking to. Because people have such difficulty understanding what others are saying, many people - in spite of their hearing aid - have less social contact with others or must retire from their jobs earlier than desired. The hearing-glasses can provide a solution to this problem, say the experts and users who have tried and tested the Varibel.

The Varibel cannot be compared to traditional hearing aids. In each leg of the glass’ frame there is a row of four tiny, interconnected microphones, which selectively intensify the sounds that come from the front, while dampening the surrounding noise. The result is a directional sensitivity of +8.2 dB. In comparison, regular hearing aids have a maximum sensitivity of +4 dB. With this solution, the user can separate the desired sounds from the undesired background noise. Dr. Cor Stengs, ENT specialist involved in the clinical tests, said of the Varibel: "Practical experience with the hearing-glasses supports the theoretical claims that the ability to understand speech is much better. There is a significant improvement in the sound quality.”

With Varibel, natural sounds can still be heard. This solution allows people to hear naturally and clearly in the direction in which they are looking. This has great advantages for daily life. Martin de Jong, audio-technician, says: "With the Varibel, the natural sounds that people enjoy are retained. This works surprisingly well. People can hear good and at the same time clearly – and especially in rooms such as in a cafe or at a birthday party."

The development of Varibel was made possible by a developmental loan from the Dutch Ministry of Finance. The STW Technology Foundation financed the research of the Delft University of Technology on the hearing-glasses and supported Varibel with the development of patent protection.

Im Focus: OU astrophysicist and collaborators find supermassive black holes in quasar nearest Earth

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...

Im Focus: What would a tsunami in the Mediterranean look like?

A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).

Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...

Im Focus: Self-healing landscape: landslides after earthquake

In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.

These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...

Im Focus: FIC Proteins Send Bacteria Into Hibernation

Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.

For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...

Im Focus: Fraunhofer IPA develops prototype of intelligent care cart

It comes when called, bringing care utensils with it and recording how they are used: Fraunhofer IPA is developing an intelligent care cart that provides care staff with physical and informational support in their day-to-day work. The scientists at Fraunhofer IPA have now completed a first prototype. In doing so, they are continuing in their efforts to improve working conditions in the care sector and are developing solutions designed to address the challenges of demographic change.

Technical assistance systems can improve the difficult working conditions in residential nursing homes and hospitals by helping the staff in their work and...
