Yup, I differ! Or better yet I should say I DIFFER
From years of various noise I have lost a fair amount of hearing, in the woods I'll almost always see movement before I can hear an animal moving, at least one of deer size, pigs are a whole different story.
Buy a good set of electronic muffs, they will run less, or about the same, as that 7mm TCU brake and much, much less than hearing aids later on down the road. Care to know what a pain it is? Drop by your local VFA hall when there are a bunch of cars out there and drop in to say hello, you'll get an earful, cheer up some boys, and learn a lot about what a PITA it is to have hearing loss.
