Exactly, any hearing aids will help the OP, the brain training (to separate the background noise) will come over time (hopefully)
@happymach has a boost in the high frequency with his OPN 1, and he wears open domes, and he’s struggling in noise with it. So OK, he doesn’t need much based on what you guys are saying, but nevertheless, he does need help with noise reduction from the hearing aids, no?
I’m sure he’s had his OPN 1 for a while already, but apparently his brain training to separate the background noise hasn’t come over time yet.
Feel free to correct me if I’m wrong, @happymach.

Kinda depends on your definition of noise.
Speech in speech noise; more HF and directional assistance.
Speech over traffic noise; more occlusion so the lower channels can be managed down while maintaining the HF and directionality.
Listening to TV; speech/background noise from same source + HF speech enhancement (directionality is redundant) with slightly more occlusion as the aid will regulate the LF better.

Thanks for that information.
Very helpful.
Yes, I’ve had the OPN 1 for almost 2 years. I really doubt that there’s going to be any more brain training at this point. More likely that the neurological features that help with differentiating speech in noise are not functioning well anymore.
I need hearing aids to do more of this work for me. You and I had previously discussed noise-cancelling headphones that either cover the ear or completely occlude the ear canal in order to cancel noise more effectively; they also offer a “transparency” mode where they reproduce and feed sound from the outside into the ear. You had told me that the “receiver” in hearing aids is too small to do that effectively (at least across the entire audio spectrum), but it does seem like blocking some of the outside noise so that the processed speech isn’t downed out would be a good idea.
How much attenuation can one expect from a “bass dome” with two openings?
I’m sure you’re misquoting me here in this context of the HA receiver being too small to be able to effectively reproduce and feed sounds from the outside into the ear. I was probably saying it in the context of HA receivers not being able to reproduced VERY low frequencies (like 20-100 Hz), typically the big booming bass sound and/or the thumping bass kick that has a lot of energy and you can feel it in your chest. Yes, the HA receiver is too small to be able to reproduce that kind of response that your ear can hear. So if you listen to much bigger type noise cancelling headphones, they can do a decent job of reproducing those thumping lows, but the HA receiver cannot.
But HA receivers should be able to reproduce the majority spectrum of where speech sounds belong with no problem. Most HA receivers can go from 125 Hz and up. When I had my audiogram test done in the sound booth, my HCP started the audiogram at 250 Hz and up.
On your question about how much attenuation you can expect from a double vented bass dome, I’m not even sure if your HCP can give you a definitive quantitative answer. He/she’ll probably tell you “Why don’t you just try it and see for yourself if you want. I can switch it in and reprogram it for you”. Hypothetically speaking, even if I’d told you that bass dome can attenuate 10 dB or 20 dB or 30 compared to open dome, the quantitative numbers still don’t mean much to you anyway. So the answer to your question is to just try it out to see if it helps. It’s an easy enough change to do as long as your HCP is willing to help reprogram it for you to match the new fitting.
When I wear my single vent bass domes and listen to music from the speaker system, I can hear the very low bass and thumping sounds just fine, they don’t attenuate much that I can tell. I’m sure I don’t get it from my HA receivers. So those low sounds must have simply gone through my single vent in my bass dome, and I don’t feel like I miss any bass sound at all. I have a subwoofer in my sound system, and even those very low ends still sound excellent through my single vented bass dome.

There’s absolutely no way that the bass dome can even attenuate 10 dB. Headphones with active noise cancellation offer 15-25dB, and that’s with considerable passive isolation, but the domes are made of a flimsy piece of silicone … Imagine less than a 5dB reduction, if that.
I had completely forgotten that the hearing aids would have to be reprogrammed with the different domes. You may remember that I’m able to reprogram my HAs myself (thanks to you!), but different domes would require new REMs?
Probably through bone conduction?
I think you completely missed my point because you’re still hung up on the numbers. I just threw 10, 20, 30 out there to illustrate the point, not to try to be accurate.
Let’s say if I revise it now to 3, 5 and 7, would you be more happy with that? It still goes to the point that your trying to quantify the numbers is futile because it’s easier and more accurate to just try it out, than trying to quantify into numbers, for what? To crunch the numbers through some kind of formula?
Yes, ideally different domes should have new REM done. But if you’re a DIY and don’t have ready access to have REM redone, it still shouldn’t hurt just trying to switch to the bass dome and change Genie 2 to re-prescribe for the bass dome, even without REM, just to see if it makes a big enough difference to you or not. If it does and you want to stick with it, then you can try to get REM done to round it off nicely. Even if you no longer have an HCP resource to get REM done, but find a big enough positive difference, then just do in-situ audiometry on top and re-prescribe to the in-situ result. It would still be better than before, even if not as good as with REM.
If it’s actually through bone conduction, then it’d still be a non-problem and I could still have a completely closed dome and still not worry about the lows not reaching to my ears now, would I? That is, if your worry is that the bass dome with vent(s) would block out too much of your very lows that would affect your music enjoyment.

Actually, I got your point. I was just musing about how (in)significant the difference between open vs. semi-closed domes must be.
By the way, I saw elsewhere your posting that the More line can be updated wirelessly via Genie 2?
I had seen that too, but when I asked my audiologist, I was told maybe in the future but not at this time.
With that said some fitting changes can be done remotely with the Oticon Remote app, it is an invite from your audiologist and phone call plus remote connectivity through your phone

Yes, only the Noahlink Wireless is compatible with it now, so even firmware update on the More has to be done wirelessly via the Noahlink Wireless. Wired firmware update is no even an option for the More anymore.
It’s been reported by many (@flashb1024 being one) that they were able to update the More to firmware 1.1.1 via the Noahlink Wireless just fine.
If we’re talking about firmware update for the More wirelessly via the Noahlink Wireless to the More, then your audi is wrong. It can be done now.
But in deference to your audi being an expert, perhaps his response was in the context of doing firmware update to the More via the RemoteCare feature. Then he’s probably right about that. But these are 2 different things we’re talking about. I believe @happymach was inquiring about firmware update via the Noahlink Wireless interface because he’s a DIY’er.

Exactly, you’ll need to download the latest version of Genie 2 (2021.2), and when you connect your Mores, the new firmware available window opens.
Nice to be able to do wireless f/w updates.
@happymach, just be aware that the update to 1.1.1 removes the legacy Music program, and replaces it with MyMusic, which is to these ears and @SpudGunner’s ears is a total fail!
There is a thread on this subject you may wish to peruse b4 you do the update.
The only workaround I’ve found that is acceptable is to create a Music program yourself.

But if - like me - you can’t do DIY by yourself, you are a spirally grooved, solid cylinder.
[Yes, 
Flash , “do DIY by yourself” is a Gunnerism.]
Ah, my mistake. I thought it was the OP who was having trouble in noise.
Aye, I did a Gunnerism!! Me so proud.
Can you have your audi dial in remotely?
He can then just duplicate your General program, and turn off NNS Change VOE to Aware, and Directionality to Fixed Omni.
Those settings are in the Moresound Intelligence screen (a true oxymoron) as far as music goes.
Then go into Automatics, and set Feedback management to Low, and disable the rest.
Voila! a listenable Music program.
What is your reference to “occlusion”
I know that to mean blockage as in blood artery occlusion.
I could not find a reference to it related to Hearing.

Wow, thank you.
Ears - hearing is complex.
My wife suffers from ear squeal, from me. Most of the time I do not hear it.
Currently I am trying a set of power domes, double seal. They seem to work if I push them in deep and I remove ear canal hair.
