I have had my hearing checked after years of shooting plus working in a vibration test lab. I always figured I was going to come up "bad" but it turns out that I have better than average for my age
My big problem is that in an even slightly noisy environment, I "loose" what people are saying - I can hear them, but unless they speak clearly and fairly loud, the background noise will kill all meaning
I guess that fact that in my early teens, someone told me about hearing loss problems, and I started wearing ear plugs - heck, I used to go to concerts wearing earplugs - I feel I get the best that way - I could feel the bass, hear the music at a reasonable level, and the crowd noise was muted to "background" - even the idiots who whistle
