I feel your pain.
I am about 90% deaf in my left ear, due to a virus I had years ago, damaging that ear.
My "Stereo" hearing is now gone.
What I do have left is a constant, low level "pinnngggg" sort of ringing sound, that really troubles me when I'm trying to focus on a sound in the woods for example.

I've tried various potions, and remedies (mostly oils). They didn't help me in my case at all.

When I hear a twig crack, I have to do a quick "snap-snap" left right look. Otherwise me hearing will fool me.
It really hurts my ablility to jump deer in brush.
I sadly will probably never enjoy that option as much as I did when I was younger.

Just really lean on your visual skills more. Watch other forest animals more, pattern the deer, so you have a better idea on which way they are going at what times, pick sites with more shooting lanes ie. more time to shoot, etc.
