I have a loss of hearing do to loud noises. I passed the hearing test to get into the USMC but after 9 months of Viatnam in the grunts I was seperated from active duty without an exit exam. I said "no problems" that I knew of. Within 4 months I knew I did not hear things like birds and crickets chirping, but did not file a claim on service related disability. Now, 46 years later, I'd like to be approved for a set of hearing aids but have too much income to have VA approve them unless I can prove service connected. So now, the question ??? What and how much documentation will I have to provide ?? Any advise will be appreciated.
