New Implant techniques help deaf people hear clearly

American scientists have invented a device that is considered as a new generation of Implant implant techniques that can help deaf people to hear clearly .

The University of Michigan team made a tiny implant implant that matches the auditory nerve. According to the researchers, the new device works more efficiently than the implant implant, a tool Technology is currently available. However, the device has only been tested on animals.

Implant cochlear implant techniques have been used since the mid-80s, and the devices in this technique are placed near nerves that transmit sound impulses to the brain. However, they are still separate from nerves by bone walls and fluid, so users often find it difficult to hear low-pitched sounds, making it difficult to communicate especially in noisy environments.

The Michigan school team has managed to successfully place their tiny device right inside the cat's nerve. They measured the acoustic reactions in the cat's brain and compared the results with implant cats of cochlear implants.

Professor John Middlebrooks, who led the study, said: 'The device placed in this position closely interacts with nerves that are able to work more accurately, helping the nerve to transmit signals to the nerves. Clear frequency, reduce the inevitable conditions of electric current and interference between electrodes when they are excited at the same time. "

According to Middlebrooks, the experiment has shown that the device is more efficient at wider frequencies, which means users will be able to hear better .

He said his team will continue to study the auditory nerve interaction with this implant for more than two years, if their work is still going well, they will proceed to experiment. in humans for at least 5 years.

Dr. Carl Verschuur, a lecturer in the audiology department at the University of Southampton Sound and Oscillation Research, welcomed the project as a "potentially great invention ". According to him, although there may still be some technical problems when connecting the device to the nerve and maintaining it in that position, this new technique is a solution to the intricate problems. Old cochlear implant. The fact that they succeeded in doing animal experiments showed that this is a promising and rewarding study.

Brian James, working at RNID, said: 'The implant implant technique has been a revolution, now this new technique if successful in humans will bring greater and far-reaching benefits'. .
