Got hearing aids, can hear but way too much

I've had severe tinnitus for a long time now. All you can do is mask it with a noise louder than it is. Nothing makes it go away. I have a hearing aid, but through the years the tinnitus has worsened to the point that it is no longer effective. I've looked at other hearing aids, but none have really appealed to me, plus our present insurance coverage covers little to nothing. I am seriously considering learning to sign, because I will likely be deaf by the time I am sixty.
