Yeah ok, so you can see that open domes in this regard is not suitable, your not meeting targets,you can see the after running the feedback test it’s limiting those higher frequencies (of course this was to be expected) but those lower frequencies look a lot better then what you had originally which was completely flat,so the issues you were having are now gone right or not?
So you can see that if you used a click sleeve or even better molds (these are vented) you’ll get those higher frequencies back, which is what you need, you could try the exact same fitting with the closed domes you have, as you’ve already posted you don’t like occlusion, but again, just to check those issues you’ve been having, and to show the difference in gain available.
And yes if you wanted you can do exactly the same in-situ fitting, my guess everything will be just a lot “louder” all round.
Talk to your audiologist about getting custom molds made up.
