When you go to the audiologist, insist that they do an air and bone conductivity. Often, they may not do the bone one. If sound goes well through the bones but not the air, you could have ottosclerosis, which is fixable with some good micro surgery. I had to have my right eye done in about 1984. Had superman hearing for about 10 days until my body turned the volume down.
Later, here in about 2001, a doctor did the left ear. It had some nerve damage in mid range; so fixing it was not quite so dramatic.
Had a hearing aid for my left ear for a while that wasn't worth too much, backfed a lot, etc.
About 2 or 3 years ago, I got $2,000 hearing aids for each ear. Still, I have troubles with hearing certain people. Luckily, my audiologist has some programs on mine, and I have a remote control that selects them that help when I'm in meetings trying to understand different people. I need captions to hear all the voices on TV.
I'm a veteran, but I didn't mess with the VA. A friend of mine is a retired marine. He got some similar to mine all paid by the VA.
