If I had "only" 85db loss average which is what Phi4sius and Miss Kat has, I would be aided way better than 30db with the same HAs I currently wear. At 1000Hz, I am aided to 40db(115db HL plus 75db gain) At 85db loss, id be aided to 10db! Was a gain of 75db ever tried? If not, how do you know it wouldn't work? Phi4sius is going to be trying just that. He's already getting huge improvements in speech with his new, more powerful HAs!
A deaf dude's life: All my audiograms thus far with my comments on them!
You can see my audiograms in my blog post. My 1998 audiogram, I had much worse hearing than Miss Kat, yet I am aided at 35db. If I had 85db HL instead of 100db HL back then, id be hearing at 20db!
