Interesting topic. One that is of high personal interest to me. Prof is right, it's the damage to the cochlear hairs that does the deed. I read a story about a woman in the Halifax, PA area that fired a .30-30 three times at a deer and effectively lost her hearing for life. She had horrible ringing, banging, etc. in her ears for life. Her father had ear problems, and had gone deaf, so it seems like it was an inherited weakness. That brings me to my point. I don't have any scientific proof of it, but it seems that different people have different sensitivity to loud noise. While everyone suffers hearing loss from loud noise, I think some people might suffer more loss more quickly than others. I know my own ears are very sensitive to loud noise, and if I subject myself to loud noise, I pay for it with ringing and subdued hearing for a couple of days. I've worked around loud noise all my life, and my hearing has suffered for it. I have tinnitis and some hearing loss. I try to keep ear plugs handy in the gun cabinet so I can take them when I go out to shoot. In an emergency situation, I would stick a set of ear valves in (which would let me hear peoples' voices, but would deaden gunshots) when I grab the firearm, IF I could do so without further endangering myself or my family by the approximate two second delay. On the other hand, if the ear protection wasn't available, or if time just didn't permit, I would go without and take my chances. I certainly realize that in a situation like this, seconds count. The noise factor and its effect on my ears is one reason I don't care for extremely large caliber handguns or hot magnum loads. I figure I have enough training to be able to hit center of mass and stop an assailant with a 9mm or .38+P, and I just can't be convinced that a .44 mag or hot .357 mag load wouldn't be harder on my hearing. If my life is threatened, I intend to survive, and I intend to do it with zero injury to myself and my family if possible. Just a few rambling thoughts on the subject.
