I think that FrankenMauser is generally correct, and as a western guy, I've generally not worn ear protection while still hunting--although I wear plugs/muffs when doing pretty much anything but cleaning my firearms.
However, I am definitely in the market for the ear protection such as outlined by Peetzakilla. Apparently, this year was a tipping point. I took only 2 un-filtered shots to fill my buck tag, but my ears have had low-level ringing ever since. I'm still about 3 decades out from reaching life expectancy age, and I plan on hearing my grand kids laughing at me. Lesson learned: I'm going to be wearing protection from now on.
