The Miracle of the Cochlear Implant

By Barbara Sinclair

Barbara and her husband, Charles, who also has a hearing loss, in 2004.

My mother didn’t realize I couldn’t hear until one afternoon when I was about 3 years old. I was happily playing on the floor with my younger brother. Suddenly I glanced up and saw Tex looking at Mother, who had clapped her hands. Not hearing any noise, I didn’t respond. Frantic with worry, Mother called Daddy telling him I couldn’t hear. She then took me to the doctor. No wonder I was slow in talking! Sound meant nothing to me. I didn’t know that I needed to talk to express feelings.

A teacher trained at St. Louis’s Central Institute for the Deaf taught me how to speak and read lips at home in Cleveland. I never heard a sound until I got my first hearing aid around age 9. The earliest audiometric evaluation I still have is from 1984, when I was 55, and it showed a profound hearing loss in my right ear. My left ear was even worse, termed “dead.” With training in speaking and lip-reading (speech-reading), I stayed in a mainstream school with the help of a hearing aid, although I really depended on lip-reading to get by. The hearing aid gave me a sense of being able to communicate, but it didn’t help much when it came to understanding speech.

I imagine anyone born with a hearing loss doesn’t always understand why they can’t hear. Many times I had wondered this myself. My doctors are also unaware of the cause. I speak a little differently, with a metallic sound and slight accent, sometimes accenting the wrong spots as I speak. However, this did not impede school or, later, work. After I graduated from Arizona State University, I held jobs in bookkeeping, the library, and human resources.

Sounds such as shouting, banging, ringing, and clanging all sound the same to me. What does a ticking clock sound like? Tap-tap, or click-click? Or running water? To me, these sound the same. I can’t hear the wind rattling the window. I feel it. I can’t hear the fury of a rainstorm. I feel it.

It’s hard for me to detect changes in speech tones or pitch, or to tell a low voice from a higher one. I read that a child’s laughter is like the delightful rippling of a water stream. I can’t identify that sound. But even though I can’t enjoy music or follow group conversations, there are some advantages to not hearing—I sleep without any interfering noises.

In 2001, our audiologist mentioned cochlear implants to my husband Charles, then age 72, who also has a hearing loss as well as being blind from retinitis pigmentosa. I researched cochlear implants and found this description from ABC News. It dates from 2001 but is still accurate today: “For those with normal hearing, sound enters the ear, triggering hair cells in the cochlea, a spiral tube filled with fluid. Those excited hair cells send information to the hearing nerve, which sends signals to the brain, allowing us to hear.

“But, if deaf people have damaged hair cells in their cochlea, an implant can also do the same work. With an implant, sound is picked up by a tiny microphone connected by a cord to a small box outside the ear. The box turns sound into a signal—transmitting it through the skin, straight into the skull. Electronics in the skull send the signals straight to the hearing nerve, bypassing the cochlear hair cells that don’t work.”

We went to see Wesley Krueger, M.D., an otolaryngologist in San Antonio. After a series of tests, Dr. Krueger told Charles that his hearing wasn’t actually severe enough to be a candidate for an implant. He was stunned for a minute, and then asked the doctor if there was a possibility for me to get an implant. Then it was my turn to be stunned.

Weeks later, following my own series of tests, Dr. Krueger came into the room, grinning, and announced, “You are a candidate for a cochlear implant!” I was speechless as he showed me the components of “the bionic ear”: the external hearing aid-like processor and transmitter; the receiver under the skin that connects to electrodes; the magnet that holds the implant in place on the skull.

I had the surgery a month later, when I was 72 years old. A week after the bandage from my right ear was removed, I felt dizzy, but there was almost no pain at all. I then realized that the implant made me unable to hear with my hearing aid. Whatever hearing I had was gone.

For 30 days I agonized whether I’d be able to hear. The incision behind the ear must heal for that period before the bionic ear can be activated. Then, finally, activation day came—and was successful! There were beeps and squawks, but I could hear! Relief enveloped me as I progressed through the programming of the device. Sounds were distorted and muddled, but they were all new to me.

It has been 17 years since the implant. My device has been reprogrammed again and again until clarity reached its peak. I still don’t understand speech perfectly, but I do hear sounds I had not heard before: a ticking clock, running water, a humming car motor—and yes, the laughter of our four grandchildren.
