I have ringing in my ears and doctors showed a graph (after testing my hearing) that showed the range of sound that I’ll never be able to hear again. They said they have hearing aids that emit a noise that’ll cancel out the ringing in my ears…but they cost about $4,000 each. Told them for 8 grand, I’ll put up with it. Someone mentioned to me that I should check with the VA as their father was a vet and he got hearing aids for free. Never followed up on it but his father said they did work well and cancelled the ringing in his ears.
