I wouldn't go to a place that sells hearing aids and have their standard tests, I would go to an ear, nose, throat doctor. I have heard there is a surgery that makes some kind of patch in the eardrum or something with fat from somewhere else in the body ... sorry, but it has been so long since I heard it mentioned that I cannot remember if it was for tinnitus or for inner-ear disturbance. I think most ear doctors will tell you tinnitus is not curable, but there are devices to mask the sound with white noise.
