This is a good question. When I was first diagnosed with AN it was by accident. Actually the hearing in my AN ear was better than in the non-AN ear. And, the hearing I had was considered within normal limits for my age. I had just lost a little but not anything they could attribute to the AN since it was basically the normal hearing ear. So W&W since 12/2005. About a year ago I started noticing that I needed the TV turned up a little louder at times. I was the one who always had the controler so I could up and down the volumn as needed. My family sometimes got mad at me for going up and down. About six months ago I really started to notice a change in my hearing. I started having problems with word recognition, couldn't understand some people at all especially if my back was turned or I was a certain distance away, I changed the phone ear to my non-AN ear, and the TV was up louder than ever before. Bothersome to say the least, but my hearing is considered serviceable according to the hearing test. So, I can say that my hearing has gradually gotten worse. I wonder about the accuracy of those hearing tests. Anyone here feel the same way? I mean after awhile you just remember the words they ask you. Why don't they use different words when they do the word recognition? Nancy
