Restoring Hearing Using Bionics

Restoring Hearing Using Bionics

A mother wrote in the Wall Street Journal yesterday about the miracle of Cochlear Implants.

Lydia Denworth described when her 2-year old son, who is deaf, got these implants and how now he is now able to attend 5th grade in a “mainstream school” and is “nearly indistinguishable from the other children.”

These implants allow her son, Alex, to have a conversation with another child about the hearing device that “can open up the world of sound and spoken language.”

Denworth states at the end of the editorial, “Moments like that make me deeply grateful for the technology.”

For me, reading this was an opportunity to go learn about the amazing bionics that has already restored hearing to 320,000 people!

While hearing aids amplify sounds and make them louder, they don’t resolve permanent damage to the inner ear.

A cochlear implant bypasses the damage by receiving sounds in a microphone, digitizing them, and converting them to electrical impulses that are sent directly via implant to the auditory nerves– bypassing damaged or missing sensory cells in the ear–in a way that the brain can understand.

I am in awe of the inventors–Graeme Clark, Ingeborg Hochmair, and Blake Wilson–who are being recognized for their pioneering research leading to the development of Cochlear Implants.

Hopefully, soon we can do for sight, smell, taste, and touch what we can do for hearing and restore the impaired to fully functioning again.

We are living in a time of great miracles–thank you G-d!

Sign Language That Really Talks

There are over 40 million deaf or hearing disabled people in the world.

Many of these people suffer from not being understood by others and feel isolated. 

Four Ukranian graduate students have created the answer for them called Enable Talk–these gloves translate sign langauge into sound. 

The gloves have sensors including compass, gyroscope, and accelerometer that captures the wearer’s sign language. This is then transmitted via Bluetooth to an smartphone app that matches the sign pattens to those stored (and which can also be programmed/customized) and translates it into words and sounds. 

Enable Talk gloves won the Microsoft Imagine Cup 2012 student technology competition, and was named as one of Time Magazine’s Top 25 Best Innovations of 2012. 

For $175 these gloves are an amazing value for the hearing impaired who just wants to be communicate and be understood by others. 

This is a great advance for the disabled, and I’d like to see the next iteration where the gloves have the translation and voice mechanism and speakers built in, so the smartphone and app isn’t even needed any longer–then the communication is all in the gloves–simple, clean, and convenient! 😉
