From a lifetime of loud engines, chain saws, farm equipment, loud stereos, loud farm animals, hunting, and a multitude of other assaults on my ears I feel like I'm closing the gate after the cows are out when I put on the "ears." However, with the first word of response being "huh" most of the time I feel the need to protect what I have left.
All that aside, I'm not going to worry about going deaf over shooting a handful of shots in an enclosed space if it means protecting life ... mine or someone else's.
