Can Future Treatments Reduce Hissing or "Cicadas" Tinnitus? Or Only the Standard "Ringing"?

I sometimes wonder about this - with all this "buzz" about these new medications that should be coming out in the near future - do you think that they will only be able to knock out / reduce "standard ringing" as most people have, or do you think it might also be able to help out with other tones as well, such as hissing, or "cicadas"? I'm just wondering about this. I hate to say this, but I have my doubts, considering that none of the scientists and specialists are really talking about this. When you do a search on the internet, there's not even any research about what may cause the different types of sounds.

I'm also a little bit skeptical that the "hissing" isn't a result of hearing loss at all, but is from something else {possibly SSRIs}. Yet, there are no answers. Nobody seems to know.

Last time I had my hearing checked {which was very recently}, my audiogram looked the same as it did multiple years ago, when my tinnitus was normal, with only one tone.

 

The ringing and hissing are often treated as part of one continuum. Many people progress from ringing at the start to cicadas/hissing at a later time. Therefore I am of the opinion that both are the same condition, and so if the hypothesis holds true that restoring correct noise to the brain will eliminate / reduce tinnitus, both should be treatable.

 

Why would the sound make a difference if they're coming from the same structural damage? I have a constant CRT hiss with 6 or 7 tones and get cicadas after a setback or spikes. It also modulates once every 5 minutes. Even so, I still have faith in regenerative medicine/research based on the current models of tinnitus/hyperacusis.
