Bad hearing

Well, I am still messing up on the birds and the biggest reason is that I can not hear good enough any more. This has really cost me alot of birds. Until I got back from Desert Storm I could hear and kill birds. Now, when they are really close I think they are farther away, so I just keep hammering away. When they are really super close in the woods . I figured this out last weekend when I was scouting on Saturday night and videoed some birds 400 meters away, and while still videoing I let out a great cut and finished with a fly up cackle and the strutting gobbler just let out a long gobble but while watching him gobble, I did not hear him. Then the next morning before dawn I set up where they went in and when it started to get daylight I had them gobbling all over. At least 5 and one huge one was sounding off. Well, I had two come in and they just skirted me and fanned and gobbled and again I did not hear it. Now, I truely know that I am getting deaf which is really disturbing. I can not afford hearaid so what am I to do. I can not hear them unless I am right on them. If I have one of my buddies they will say hear that bird, of course not. So I really do not know which one to go to. Steady
