I have several thousand hours in C-130's. The VA provides my hearing aids, and I have a 10% disability which provides a portion of my retirement to be tax free. I got it based on being in Nam at Pleiku in 69-70 and I tried for the program where Nav's could cross train to Helecopter Pilot but failed the hearing test at DaNang. I was given my first set in the 90's and am going to get a new set next month.
Hope this helps.
