You could try NAL-NL2 with your Lumitys. Most HA OEMs offer several different fitting formulas in the fitting software. Your HCP could advise you, especially from being familiar with your likes and dislikes. Here’s a list of the fitting algorithms available for the Lumity P90 in the Target fitting software.
If you’re into “comfort,” you might like the proprietary Phonak algorithm better. NAL-NL2 is open source. DSL5-Adult is another popular alternative fitting algorithm. I think it’s licensed from the University of Western Ontario, where it was developed. But both NAL-NL2 and DSL5-Adult amplify the highs a lot more than ReSound’s “comfort” Audiogram+, and I would imagine the same is true vs. the proprietary Phonak fits. DSL5 was a little too much amplification for me. I think high-frequency amplification helps me with speech recognition. There are sounds like our security alarm keypad alert that are so high frequency that I don’t hear them well without my high frequencies cranked up, too.
I thought the Lumitys were excellent hearing aids, and if they were available with disposable batteries or rechargeables with a longer runtime, I might have gotten them instead. I found the MyPhonak app very powerful, but a little slow and clunky compared to the ReSound app, and I especially wanted to be able to control my HA’s through my Apple Watch Ultra (one of the reasons I switched from Android to iPhone was for the ability to do that!).
I thought AutoSense 5.0 worked great for the most part, but sometimes it was too aggressive (turning on running aerated tap water while my soft-spoken wife was speaking to me from the side instantly cranked up aggressive noise suppression making her voice hard to understand). But Speech Enhancer was a killer feature for me. The Omnias with M&RIE receivers weren’t quite as good as picking up her soft voice, but they were much better than my ReSound Quattros and quite good enough (like you, noisy situations are a very infrequent occurrence for me. I’m 85% or 90% in quiet environments). Perhaps the natural pinna effect that one is supposed to get with the Omnia M&RIE receivers really works for me and functions a bit like a natural speech enhancer. I imagine my sound localization is much improved, but that may be the placebo effect (the power of suggestion).
I thought the Lumitys focused on making speech very clear and sometimes cut out environmental sounds to do that. The Omnias in All-Around mode seem closer to Oticon Mores and Opns in attempting to let you hear everything around you, even more noise than the Lumitys, IMHO. I’ve never tried the Oticons, and if I were you, you might want to try those next as something very different from Phonak. They get rave reviews from users on the forum. I’d say the Omnias are somewhere in between in terms of focusing on speech vs. hearing everything around you.
