phones with tactile impact help deaf   A group of researchers from the Massachusetts Institute of Technology (Massachusetts Institute of Technology, MIT) is developing for the deaf and hearing impaired people a device that converts sound waves into vibrations. Usual for this category of people reading the speech the other person on her lips did not always correctly perceived by the listener, and the existing assistant implants is very expensive and not everyone is available. A group of MIT Electronics Research Laboratory, under the leadership of Charlotte Reed (Charlotte Reed) has developed a prototype device that converts sound into vibrations.
The apparatus consists of two vibrators - one for low frequency sounds, the other for high frequency. The main problem of the transformation is that the human ear perceives sound waves with a frequency of up to 20000 Hz, and tactile sensitivity is limited by a threshold of 500 Hz. Ideally, the developer should get a compact device, attaching the arm to which people can touch to hear. Naturally, the cost of such a device would be small. In addition to the hardware component of the researchers working on software that you can use the phones and smartphones with tactile impact.
