Greetings all, There were many cold mornings that I remember. The thermos of hot coffee, and the dawning light of day would find us in the duck blind. The smell of wet dog, hot coffee, and warm gun barrels makes it easy to remember the carpet of magnum shell casings on the floor. Yes, it is loud work to shoot ducks. There is also the aural memory of how sharp the crack of a .30-.30 deer rifle was on a cold winter morning. Being taught by our government how to shoot a machine gun out of a helicopter window ................ These things stay with you. These things are LOUD! So, it was not a surprise to have the audiologist tell me that there was a case of classic explosion damage in my left ear. It takes the form of a 40% drop in sensitivity to frequencies between 3500 and 4200 Hz. This is the top of the piano's range and they mentioned that most people with this loss would not even know it. I knew it; though my unisons at the top were clean, it sure was taking more work, and I found that the SAT was tuning cleaner unisons than I was up there. The implications for voicing are much more serious. Soooooo......... I went to the hearing lab, and got fitted with the latest in digital technology. The Digifocus system, by Oticon. This hearing aid has seven discrete bands of amplification, it is set to match ones inner ear harmonics by computer, and given the steepness of the slope on my hearing chart, was the only viable equipment. A broader range of amplification would boost areas that didn't need boosting, creating confusion and a horribly distorted sound. When it was all tuned and set for what I wanted, we had four out of seven bands turned off, and the others were tailored to match the narrow, specific, loss that I had. I am now able to now hear the apparent sharpening of a note as the decay makes it's effect known. I can tell the conditon of string level by ear now, whereas before I had to lift the hammer to the string. If anybody would like to know what it is like, I will be glad to post the R&D that we went through to get it right. And it is right. I am tuning cleaner now than I have in years!
