Yes, I reported on that after taking an Audiology Online course back in September 2021 in which ReSound summarized their recommendations after the ReSound Ones with M&RIE receivers had been out and in use for about one year. (see graphs in my post)
OTH, Dr. Cliff, in a YouTube video, has said that he’s successfully fitted patients with loss that doesn’t match ReSound’s advice and that patients that he’s fitted with the M&RIE receivers prefer those to standard receivers.
I think part of ReSound’s advice might be grounded in the standard practice that people with good low-frequency hearing should have a relative open fit so they don’t have occlusion and can use their own good hearing and pinna effect with an open fit to good advantage. You can’t have an open fit and serious high-frequency amplification with M&RIE receivers, or you’ll get feedback galore.
OTH, if you’re like me and wear a totally occlusive fit, you’re essentially also relying on your HA’s for even low-frequency amplification. So I’m essentially having myself fit like a moderate to severe loss across all frequencies. And I am probably pushing the M&RIE limits. I have to have an ~almost perfectly fitting mold or I’ll get feedback. I am also pushing things by employing the NAL-NL2 fitting algorithm, which amplifies high frequencies a lot more than ReSound’s proprietary “more comfort” Audiogram+ fitting algorithm.
So if I can’t get a good enough fitting left mold with a ReSound remake for my left ear, I may just switch to Audiogram+ or just cut back a bit on NAL-NL2 high-frequency amplification for my left ear to compensate.
