You probably have developed your brain hearing well enough
Let me reiterate that this is not what Oticon’s moto means. Oticon is trying to use what we know of how the brain hears naturally to optimize their hearing aid processing, which is a great goal. They are not claiming that their hearing aids develop your brain in any unique way that other hearing aids do not.
I agree that Oticon is not claiming that their hearing aids develop the brain in any unique way. But I maintain that what Oticon is saying is that with the open paradigm, it’s OK to want to hear more sounds around you if you so desire, because your normal brain hearing (the normal way people hear, not any special other way) will take care of it. It’ll learn to adapt and differentiate between different sounds and be able to focus on what you want to hear more, including speech (with a little help from the Oticon aids to make the speech a bit cleaner). You don’t have to shut off all the surrounding noise as the only way to able to hear speech.
So Oticon is not saying that their aids helps develop any special kind brain hearing. Oticon is just saying that don’t be afraid of the open paradigm because your normal brain hearing will take care of the sorting out for you. May take some time to adjust if you’re used to speech exclusivity before, but you’ll get there.
One caveat, I think, is that this doesn’t necessarily apply to everybody. I think folks with much heavier hearing losses such that they wide dynamic range compression is too heavily compressed, there’s not enough wiggle room in the compressed gain to really sort out the different sounds as well.
That’s why when @e1405 switched from the More to the Lumity, he said that OK, there’s less surrounding noise with the Lumity and speech seems crispier and clearer than the More (probably because of the speech exclusivity), but hey, he can still understand speech with his More just fine as well, even if it’s not crispier and clearer.
I can’t speak for @e1405 on whether he would understand speech just as well with the More if he’d started out exclusively with the Lumity first, becomes used to the speech exclusivity, then gets overwhelmed initially with speech understanding when trying out the More next, because the open paradigm lets all the noise in to compete with the speech.
But while I can’t speak for @e1405 about this, this is the EXACT thing that happened to me when I went from a pair of Costco Rexton aids that had frontal beam forming in noise to the Oticon OPN aids. I was completely overwhelmed in a noisy place and could not focus on and understand speech, because I was already accustomed to the speech exclusivity in the Rextons. But eventually, I learned to adjust and re-adapt and regain my normal brain hearing to learn to focus on speech and filter out the noise.
