How to go about my hearing loss from work?

My name is Danny and I'm 17 years old. I'm not gonna say what company I work for but our store plays music that is too loud and not safe for my hears. I worked their for 6 months now and I've noticed that i've had significant hearing problems now due to working over 20 hours a week. I did some research and read that hearing lost starts at 85 decibels. My manager at work told me the loudness of the music is decided by corporate. My question is: is their any legal actions I could take?
