I lost a lot of high frequency sounds in my left ear when I shot a tom perpendicular to a 200 yr old oak I was set up against. The sound must have bounced right off the tree and back into that ear. That ear rang deafeningly for a week.
I noticed in the years that followed, I could no longer pinpoint the direction of gobbles, as my right ear was much better than my left.
I finally went to my ENT and had my hearing checked and got a pair of Soundscopes hearing aids made specifically to my canals. I could hunt with them turning up my left ear to full volume and my right ear to half volume and tell exactly which direction a gobble came from. I used them for a decade or so, then lost them in a field working around a bird. At $400 wholesale, I've been too cheap to replace, so I now use a walkers alpha 360 earmuffs. Again, turn up the left ear volume to full, and the right to half and works fine. Way more bulky, and gets hot in the second half of south MS season, but at least I know which direction to head when I hear that first gobble.
I can hear drumming when the bird is within 50yds, but can hear the spit from 80 yds away.
I may bite the bullet and get another pair of custom made hearing aids sometime.
They do cut out with loud yelping, but usually stay on with soft to mid volume calling.
