Your loss in some ways is similar to what I have in my left ear. You are on the margin where a custom mold is needed to avoid feedback, when you are given full prescribed gain. Are you trying the closed domes or closed sleeves? The Connexx software is showing that closed domes are not good enough to avoid feedback, but the closed sleeves may be OK. It kind of depends how well they actually fit you.
The software does not suggest frequency compression for your loss. My fitter told me the same thing as yours. They really only use it as a last resort if the user cannot hear the higher frequency speech. I would agree that you are probably not a candidate.
I would ask for some closed click sleeves to try if you have not already. Another thing to try are different fitting formulas. There are three basic choices; Signia proprietary fit, NAL-NL2, and DSL v5. And if none of that works, you may want to think about custom molds.
If you want to see what other fittings would be like, post a new thread. I don’t want to drag this one down with Signia stuff. I recall we may have discussed options before in another thread…
