I found something interesting. I think the Oticon More uses this platform.
Thanks, @Kem103. Itās an intersting paper, but More uses the Polaris platform, and not Velox.
The Wind Management module probably works in much the same way on Polaris as it does on Velox and VeloxS. (Perhaps @Volusiano will chime in and explain.).
I am using mini fit, bass 8 mm, double vent.
Yep, you are driving way too fast. But the info does help.
You wouldnāt want to ride with me when I go on the highway here in Arkansas or Texas where the speed limit varies from 75 to 85 mph.

@SpudGunner is correct that the More is on the Polaris platform, the OPN S is on the Velox S platform, and the OPN is on the Velox platform. I think itās also safe to assume that the More uses the same wind noise management technology as the OPN and OPN S.
However, wind noise management is for wearing the HAs out in the open road, like when youāre on a bicycle or motorcycle or an open boat. If youāre in a van driving with close windows, I assume what you hear is the loud road noise because thereās really no wind inside the van. I assume that @Kem103 was just using a figure of speech to call it being like in a wind tunnel, but really it was just road noise.
@Kem103 didnāt say which More tier heās on. If itās the More 1, itās very possible that his Difficult Environment Max Neural Noise Suppression level is set to the default of 6 dB, which is the max for the More 3, and not at the max 10 dB that can be set for the More 1. That would be the first thing I would try to adjust (to 10 dB) to see if it would help suppress the van noise better.
I donāt know why the car noise in Kem103ās situation is better than in the van noise. It may be that the car has better road noise insulation than the van. It may be that the road on the trip is not as smooth on the tires then in-city driving so the road noise in the van on the trip is more pronounced. It may also be that the carās tires have better road noise absorption than the van. It may be a combination of all 3 as well. Nevertheless, the most obvious thing is to make sure the Neural Noise Suppression is maxed out for Difficult Environment, and even for Simple environment as well. Thereās really no reason to keep these settings at any lower level than the max level allows, because if thereās less background noise, the HA will be smart enough to apply less noise suppression anyway.
If this doesnāt help a lot, the Sound Enhancer can be set to Comfort, and the Virtual Outer Ear can be set to Focused for even more sound rebalancing. However, these 2 settings are not Max setting, so adjusting these should be done with a little more consideration because they may affect other perception. The middle ground settings for these 2 parameters of course is Balanced.
See the screenshot below for the parameters Iām talking about.

Wow. Thank you for the information. Iāll pass this on to my Audi.
The car is a Lexus which has noise reduction wheels and other sound suppression features so that may account for the less noise in car. However, the opn Mores made it uncomfortable sound-wise versus my Reounds Linx. The same route was taken in the van today. The noise was extremely uncomfortable and I removed the hearing aids with a sigh of relief.
I am trialing the Opn More 1.
I appreciate the level and quality of information. You may just saved my Audi a sale if she will use the information. Iāll keep you all posted.

Just a slight correction that itās the Oticon More 1. Oticon is the company, OPN is the original model from Oticon, followed by the OPN S, followed by the More. It can easily be confused, especially you throw in it the āopenā paradigm on top. 
Yeah, the Lexus is a nice quiet ride for sure. I used to own one. The open paradigm of the More (as well as the previous OPN and OPN S models) for sure will let you hear a lot more road noise than a more traditional HA like the Resound Linx. Itāll take about a month for you to start getting used to hearing too many noises and for your brain to start to learn to ignore them and focus on the sounds that you want to hear. But maxing out on the Neural Noise Suppression settings and the other 2 settings should help alleviate some of this discomfort initially.

Volusiano,
Thanks. My challenge is that there was only road noise. I considered turning on the radio because there was no other sound on which to focus. I will try the Neural sound adjustment and the Sound Enhancer and Virtual Outer Ear settings per your screen captures.
You mentioned āweā took a road trip, so I assume that there was someone else in the van? If so, were you able to have a conversation with them OK when thereās speech going on? Itās supposed to balance out the sounds when thereās speech going on so you can understand speech better, but as soon as speech stops, youād be hearing the road noise again.
One option if you donāt have other sounds going on to focus on but want to minimize hearing the road noise is to turn on the MoreSound Booster option which is available in the smart phone ON app. This is supposed to change the Directionality setting of the More to Full Directional so that the surround sounds get reduced more aggressively so you can focus more on the sounds coming from the front. This should help reduce the road noise although youād still hear it coming from the front somewhat.

I am having trouble describing the sound. We talked earlier about road noise, but I now know that it is not that. The sound is not static, squealing etc, It is a constant hiss or constant wind. Sort of like in the movies where someone is walking in the Artic and there is the wind noise (not crunching on the snow.) If I pull out the hearing aid to less depth in the ear, the sound disappears but so does the ability to hear better. I see my Audi tomorrow but first I thought Iād ask if anyone has/had this issue. Iād like to keep trialing the More because I like the clarity of speech understanding. Could this possibly be a dome issue?
If you are boosting the volume too much with the ON app, you will hear a persistent āelectron hissā that is particularly evident when there are no other sounds present. You can reduce the volume setting to make the hiss go away.

This is going to sound really stupid but donāt get mad at me. I see lots of comments about wind noise. I havenāt been out on a windy day so I really donāt know what to expect. Just to try and get an idea I stuck my head in front of a window fan. I felt the breeze but all I heard was the fan motor as I normally do (yes a little louder as my head was on top of it). Was that a useless test and I need to be out on a brisk windy day to see if that wind noise reduction really works?

I wish it were a hiss. To use another example, it is like hearing the ocean waves, but at a broader, fuller sound (not electronic, not hissing, not high pitched, not squealing). Iāll search for wind noise and maybe someone has found a solution. I really like the More.
Eskie227: I appreciate the fan test
Volusiano: It turned out that the same situation happened in the car with the left hearing aid. There was no one in the car with me and this time I paid more attention. I noticed it more in the van because it was a conversation about a surgery and I was trying to hear every word from the 2nd row and the wind noise superseded the voices. I have forwarded your recommendation on Neural Noise Suppression to the Audi. Hopefully, that will fix it.
I should clarify that the wind sound occurs constantly, not just in the car. It seems related to the depth I put the receivers in the ear. The Audi said that I needed them deeper. (insert down and then up for full integration.) Also, if I press on the wire that comes from the bottom of the hearing aid casing, the sound can sometimes be replicated.
Could you please tell me what the volume setting is on your ON app, and for which program? (Under normal conditions, it should read zero - which simply means that volume is being neither increased nor decreased. If the setting is, letās say, 4 - you will get that sound that you might interpret as surf sounds , but which I would call a hiss.)

My take on wind noise: What I mean by wind noise is when the wind strikes the microphone openings creating a hars blowing sound (somewhat akin to blowing air over a bottle opening) I donāt think this can be fixed by electronics as I can hear it to a certain extent even with hearing aids off, although itās definitely worse with them on. I think the āfixā is better designed microphone openings. Some hearing aids deal with this by detecting it and then taking the sound from the hearing aid with no or less wind noise and copying it over to the other hearing aid.

That seems to work. Thank you! When I drive to the Audi tomorrow, Iāll share the news.
As a side note, I went to this site to find a sound similar to what I was hearing to share on this thread. Maybe it will help those with tinnitus, although tinnitus options are available with some hearing aids. The iMac version has many more sounds. On devices, use the menu on the right. P.s., I did nit get paid for this advert.

In the old days, a ādirtyā (cheap?) analog amplifier would have the floor noise be quite audible if you crank up the volume, because the signal to noise ratio of the amplifier is poor. Nowadays with digital amplifiers, the SNR is good enough that youād be hardly pressed to hear any floor noise.
To my surprise, when I first got the OPN 1, although I didnāt notice any floor noise, whenever I put it in full directional mode, if Iām in a quiet environment, I would notice the floor noise if things are quiet enough around me. I started reading up and sure enough, there has been research papers mentioning this effect in directional modes via microphones control. Generally, in this mode, it would cause a low frequency roll-off, and as a result, the system compensates through amplification at the low ends, resulting in higher internal mic static noise level (what I call floor noise). I learned about this when I was trialing the Sonic Enchant 100, where they tried to solve this issue by creating a multi-frequency band design so they can leave the lower frequency bands in omnidirectional (to prevent the low frequency roll-off issue) and only activating directionality in higher frequencies. But apparently the OPN doesnāt have this multiband design feature because I can hear the floor noise in full directional mode.
Anyway, to make the long story short, it sounds like what @Kem103 is hearing in the car or van may be this floor noise, especially confirmed if itās diminished when the volume is turned down. Perhaps the More somehow switches to Full Directional mode for some reason in the car and van, maybe because the conversational speech wasnāt clear enough, and this resulted in the low frequency rolloff amplification to compensate, making the floor noise heard more clearly.
Of course this is all a guess. But if itās not the road noise or the wind noise and it sounds like the constant floor noise of the amplifier, then this is the only plausible thing that comes to my mind.
If playing with the MoreSound Intelligence parameters in the screenshot below doesnāt seem to help, you can try to have the audi create an custom program for when driving and set the Directionality Settings to Fixed Omni (as seen in the lower right hand corner of the screenshot below). This will force the More to not be put in the Full Directional mode, thereby avoid the low frequency roll-off situation and help minimize the floor noise you hear. However, this may force you to hear the road noise more, so you may end up avoiding one thing just to hear a different thing anyway. But itās worth trying out, so that if it helps, whenever youāre driving, you can go to this program which is optimized for driving, then return to the default when youāre not driving anymore.

Itās possible you are just hearing new sounds that you have not heard in a long time, donāt know or understand them. These new sounds can be like your description. My hunch they will slowly turn into recognizable sounds in time. You just need to give your brain time to learn them.
