Visit a local audiologist. They can give you some real world options. I've had tinnitus ever since a practical joke explosion at work many years ago. It's more and more debilitating as time goes on, because the tinnitus gets progressively worse and takes more and more hearing with it. I had a noise cancelling hearing aid early on that did mask some of the noise, but now it's gotten so bad, nothing will touch it. So that's my advice.
