My Dad and me on Hilton Head. His sister Helen is behind him and he is, as usual, making a wisecrack.
One of the most interesting things that happened to our family in the last decade of my father's life was a curious-looking invention he wore around his neck. It looked like a black plastic necklace. But it was a high tech hearing aid, invented by Professor Bernard Widrow of Stanford University.
My father's hearing was badly damaged during the years he served on the Sixth Army Pistol Team, where he won dozens and dozens of awards firing .22s and .45s in competition. If you can believe it: nobody wore ear protection back then.

So, by the time Dad was in his sixties, he was wearing hearing aids. By the time he was in his late seventies, even the best hearing aids in Silicon Valley were not helping him enough.
His audiologist told him about a professor at nearby Stanford University who was working on a "microphone array" for use with hearing aids. My mother and father were nothing if not resourceful and determined, so they got in touch with Professor Widrow of Stanford's electrical engineering department and the next thing we knew, our Dad was wearing his black, plastic necklace.

I'm not an engineer, so I can't tell you exactly how it works. I get the idea it is a sort of stereo speaker system for the ear. Professor Widrow's website says this:
"This method enables the design of highly-directive hearing instruments which are comfortable, inconspicuous, and convenient to use. The array provides the user with a dramatic improvement in speech perception over existing hearing aid designs, particularly in the presence of background noise, reverberation, and feedback."
The only part I'd disagree with there is the "inconspicuous" part.

In going through my father's things after his death, I found the Widrow array and some notes Dad and Mom had made on the instruction booklet that came with it. I knew my Dad had ceased to wear it during the last two years of his life. And I wondered what had happened to the project. It had helped my father extend the time during which he could hear our voices. Yet I had never seen the microphone array on anyone else.
So, since I figured Professor Widrow would want a follow-up on my father's case and would be interested in the positive difference it made, I mailed the microphone and my father's notes back to Bernard Widrow at Stanford. I thanked him for the work he had done that improved my Dad's quality of life.

The good professor called me up immediately when he recieved my package to tell me he is hoping to get the device into production very soon. He was interested to learn more about how my Dad had used his, and how long it had continued to work for him. I sent him lots of photos. You can't exactly miss this inconspicuous invention.

I wish Bernard Widrow all the best in his effort to market and sell his device. My father was lively and intelligent and it was devastating to him to find himself treated as if he were stupid because he couldn't hear. Watching his struggle taught me so much about how callus we all are to the disabilities of others, especially the disablities of the elderly.
And every invention that comes along puts us one step further toward understanding. Each person who asked my father what that funny-looking thing was around his neck had a small lesson in what it must be like, for a bright-minded senior, not to be able to hear.
In the end the most joy my father got from the device was to be able to hear my mother's voice. It was just a little thing, when you think about it. But it meant the world to him.
