I hear this is a big deal

Cali_Chuck

Jon - thanks so much for putting a light on this. My 83 year old father has had bilateral cochlear impants (e.g. one in each ear) for the last ~8 years. He often says they have changed his life. He began having hearing loss in his mid-50s and by his 70s not even the best hearing aids with highest amplification could get through to his brain. He went through every day essentially deaf - and he has vividly described what it's like to go out on something as simple as a shopping trip or trying to fly to see your kids as a deaf person. He did the first implant - which worried me enormously as I was skeptical of the technology after doing lots of research. But Cochlear (the company) has a great program where they have "ambassadors" - patients with implants - who line up to talk to prospective patients about the experience. They convinced him, and his biggest regret is he didn't do it years earlier. He got the 2nd implant as soon as they would allow it. (Having two implants is very uncommon - among other side effects it can create balance issues as the inner ear is responsible for balance.) In fact he is experiencing this very effect and is medically categorized as a fall risk because of it, but he considers this a small price to pay for being able to hear again, if not perfectly. The brain does indeed retrain itself to process the stimuli from the electrodes into speech - takes several months but he hears my "voice" now as he always heard it when his ears still worked. I'm an RF engineer and much of what the cochlea does makes intuitive sense as a linear series of frequency-dependent resonators. People stop him all the time at the grocery store or other places to ask about the implants for themselves, a spouse or other family member. You've done a great job (as usual !!) with this piece and I learned a lot of which I was unaware despite lots of experience and research on the subject.

In the USA, I was deaf from age 4 (measles) through 11 (early Edmonston-B measles shot ... but, based on other patients, coincidence). The best part about getting my hearing back was the end of summer-ruining quack surgeries popular at the time (I had three of them and a fourth scheduled).
