While I agree to an extent, I believe current conditions play a lot in how sound is processed. I have sensitive ears, and wear ear plugs a LOT. I own/operate a tree service, and wear them nearly all day at work. I use them when running a push mower, even a skilsaw. However, I have, on more than one occasion, shot a deer, without hearing protection, and heard the deer fall. My theory is that adrenaline shuts off the hearing circuit to protect it, but that may not be correct. I just know shooting a can will deafen me, while shooting at deer does not.
