I'm only 24, but I'm suffering the results of 120 db Car stereos back in HS..... I have a hard time understanding things on the phone, especially when accents are involved. Even face to face I have trouble distinguishing words alot.... but I can tell subtle differences in pitch, and vibrations in engines, and can still hear a deer jump a fence when I'm on the stand, so for now I guess I'm ok.

My dad though has been working in factories most of his life.... alot of which without earplugs.... he has to turn the tv up FULL BLAST just to have a chance at understanding what they're saying. He wont go get hearing aids though...
