The method, which can also be adapted for infants, has been developed by engineering researcher Parivash Ranjbar, who is submitting his findings in a new dissertation at Örebro University in Sweden.
Above all, individuals who are both deaf and blind are a vulnerable group that find it difficult to understand what is going on in their surroundings. But the new aid, which has been named "Monitor," enables them to distinguish different kinds of sounds, such as voices, telephones, birdsong, cars, thunder, rain, and wind.
"After brief training, one of my trial subjects could even understand what was being said in a conversation," says Parivash Ranjbar.
"The deaf-blind already have an acquired ability to glean information from vibrations. For example, they can recognize the step of different individuals through the vibrations in the floor, or feel the vibrations from a pot when the water starts to boil. But with Monitor, they have entirely new possibilities of keeping up with what's going on in their surroundings, and this makes them feel much more secure."Easy to use
"It was easy for the trial subjects to learn to use it, even for those who were born deaf and therefore have no sound library to fall back on."
Monitor, which is small enough for people to carry with them everywhere, consists of a microphone that picks up sounds, a processor that converts them, and a vibrator part that conveys them. The vibrator can also be mounted in pacifiers and bottle nipples to provide infants born without hearing with a chance to become familiar with sounds through their lips and perceive what is going on around them.Early learning
"Many more aids can be developed using this technology, such as helping people who are deaf and blind to ride horseback, using vibrations that communicate their position on a track. I'm constantly getting new ideas when I see the needs and possibilities actually exist," says Parivash Ranjbar.
Parivash Ranjbar is a computer engineer with a background as a practical nurse, and much of her research was carried out at the Audiological Research Center in Örebro.

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...
Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while...
Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
