about the only way i can think of would be a device like the walkers game ear.......im going to try my earmuffs this year...just to see if the amplify sounds any......i got a tactical pair just for the range.....dad got them for me.......nice being able to hear people at the range...but no noise from gunfire at all...very neat.....and adjustable to lower or louden the lower noises...like people talking....birds gobbling...so im going to see if they "help" me hear birds gobbling......and groundhog hunting and dove hunting im definently wearing them.........my hearing is taking a beating....and i never did anything about it...i do wear protection when at the range...about half the time....i wont lie...i used to all the time when i was young....but id always forget them when i started to drive......i think my tactical ones made by peltor or something like that are 120-150ish...kinda pricey...but i dont know any other way to save your hearing...but hear birds gobble.....
