There's a lot of new things coming out in hearing aids these days, due to extreme miniaturization and the ability to run one for a long time with very little power. Fortunately, since my hearing loss is not too severe, I can wear the
Lyric , which is hidden in my ear and stays in for about 3 months until the battery runs down. I even jumped into a lake a few months ago because I had forgotten they were in, which I'm not supposed to do, but they kept on working.
If you need a little more help, say your high frequency range is totally shot, you can get digital hearing aids with frequency shifting or frequency compression. You may never be able to hear high frequencies again, but the hearing aid can, and it can move those frequencies down to a range where you can still hear them. You wouldn't be able to hear the full range of an orchestra, but you could hear every note, albeit at a lower frequency than it was played. These are getting small enough to be hidden in the ear too, although not for extended wear yet. The Lyrics go from year to year, and I may try a pair of the hidden in the ear digitals at the end of this year to see if I like them better.
Even though the Lyrics don't really extend the frequency range you can hear, they work really well for hunting, because my experience is that the sound of an animal walking through the forrest has plenty of mid-range noises to pick up. Plus, being more or less permanently in your ear, they are one less thing to keep track of on those early morning starts.
A few years ago, I spent $900 on some higher end amplified hearing earbuds that are supposed to protect your ears against loud noises too. They are fine, I guess, but within a year I ended up getting hearing aids anyway, so it turned out to be kind of a waste of money. I think those are a better idea for someone who doesn't really have a hearing problem, but wants amplified hearing and hearing protection for hunting.
