happened to me when I was 17, I was driving and my friend shot a .22 rifle out the back window and the end of the barrel was like a foot away from my right ear....even though I held both hand at my ears after he shot (boom) my ear popped...for like a week I had about 80% hearing loss in my ear and it slowly came back, however do THIS DAY, THIS MOMENT , I have ringing in my ear because of that..i just learned to live with it..and that was over 10 years ago......use protection from now on bro......
