I've said this before
A key part of my defense plan is to wear electronic shooter's muffs when the alarm (yappy dog) goes off. My hearing sucks to begin with, so the amplified muffs will pick up sounds without my having to fumble for my hearing aids; if (lord forbid) I do have to fire, at least they'll blank out the sound. Damage is damage whether you perceive it or not.
