“What are you saying?”
If you’ve spent much time at a skeet or trap club, you’ve probably noticed some of the older members of the club talking loudly and asking you to repeat what you just said. Perhaps multiple times.
For most people, hearing loss is a function of at least two factors: aging and exposure to thunderous noise. In addition to aging, these older gentlemen likely started shooting long before anyone paid attention to hearing protection. They may wear some form of protection now, but the damage was done long ago.
