Gotta agree with all the other posters...USE HEARING PROTECTION.
I didn't when I was younger and have ~70% of normal hearing now when there is no background noise. With background noise such as wind or in a car going down the highway, my hearing is only ~24% of normal.
It is amazing what I can't hear. Had some company over the other night and they commented on all the locusts 'singing'. I couldn't hear them and haven't heard them for several years. I can see various song birds singing when I see them, but cannot hear them. Finally got a hearing aid a few years ago and that does help, especially for hearing turkeys gobble in the spring. I now wear foam plugs whenever I am around any equipment and use both foam plugs and muffs when shooting.
PLEASE guys, protect your hearing!
