If they have the same receivers they both have the same gain potential.
The size 13 batteries will just last longer between changes.
Are you programming with audiogram direct? Running feedback manager? Stay with those and Target recommendations and you will be close.
Thank you for clarify about the size. I do have the same receivers. I even went ahead and got a pair of cshell so they are both the same. I tried to copy the program from the v90 to the b90 but still not getting them the same as I used to. I may have to wipe the b90 and start over like you suggested.
You can try to use transfer fitting, which allows you to transfer data between different hearing aids.
Thank you. I will try to transfer the fitting later tonight. I learned how to program the buttons on the b90-312 to act as the volume control so it does help a lot. I been playing with the program and I need to find out a way to make the female voice louder so I can hear my wife and daughter better.
Well it’s been many months since I started this thread, and I was surprised to find it’s still active.
I finished messing with the programming back around July and have been very satisfied with the results until about a week ago, when I thought it was getting a bit more difficult to clearly hear voices on TV and certain other sounds.
Living in the SF Bay Area, we have been under a stay at home directive keeping our distance longer than anywhere else in the country, and I would not have looked forward to having to visit an Audiology department. Thankfully all it took was a short trip to my desk to fire up the Target software, run an audiogram direct test to validate that my hearing had indeed fallen off a bit. Based on the test results I made a few programming changes, ran some sound clips from the media library to make sure everything was dialed in correctly and all is good again.
I should mention that in August I developed a problem with one of the my aids. If anything bumped against it like my eye glasses it would send a loud click to my ears. After doing a wide internet search, and choking on repair prices I ended up sending it to Dallas Hecimovich who has an Ebay listing as meds4.2
This guy did great work for a very reasonable price, and my aid came back better than I expected. If you ever need a hearing aid repaired, I would give him a try. He’s not real fast, but that was not an issue for me because I had a pair of backup hearing aids to use in the interim.
All things considered DIY is the way to go. Especially during these times.
I didn’t mean that he was crazy. It was a joke about name confusion. At least one newbie went out and bought a NOAHlink on EBay because of said name confusion. He bought this;
What he really wanted to buy was this;
Congratulations, glad self programming is working out for you.
I too think about all the members needing a fitter to do something with their aids and having a tuff time. Us DIY folks are doing ok.
Glad it worked for you. I have tried what I think is same feature (Oticon’s In Situ Audiometry) and the result for me was not as good as the settings that match my audiogram. Tried it for my wife with a similar result. Our original settings were better.
I use the Audiogram Direct as a relative indicator rather than cast in stone. If I compare a current reading with one from the past, and see a change, that indicates that some programing changes may in order.
What really counts is making the changes and then listening to the Phonak media files. In my case the programming changes were validated by listening to the media files.
The biggest problem I had was remembering how the Phonak Target software worked. 
That method makes a lot of sense. Fortunately for me (and her) our loss has been stable. Another remedy is to make a Costco Hearing test appointment and demand a copy of the audiogram! But with today’s stay at home/social-distancing rules your comparison seems to be a better solution.
@dacuttler I too have found Phonaks Audiogram Direct to be better than tests from professional fitters. I suspect Phonak may have an edge on this technology but that is just a guess. Other members have also had good results using Audiogram Direct.
I find AudiogramDirect to change depending on which dome I am using. The more open the dome, the more low frequency loss I have and the worse my loss is.
That makes since to me too.
But, even with different acoustics you end up with a better fit for speech understanding. The prescription bends as needed for the acoustics you use. At least that is how I see it but I am still learning.
I am using custom ear molds with 2.5mm to 3mm vents, and I am ok with lower frequencies, but it’s the higher frequencies that have been slowly getting worse, which is not unusual for someone in their 80s.
One of the most valuable features of the target software is being able to play different components of speech from the media files, making program changes on the fly, and hear in real time if it helped.
When I started down this path last year, one of the first things I did was to make a trip to Best Buy for some decent speakers for my computer so I could play the media files. Laptop internal speakers just don’t get the job done for testing your hearing.
I was pleasantly surprised and encouraged to read your post… I had the same revelations some 10-15 years ago and set out accomplishing the same goals. Using a serial port HIPro and Connexx software I programmed my Seimans Artis aids. Now it seems I am going to have to relearn almost everything, as I am suffering debilitating tinnitus. I was in sticker shock at the audiologist when I priced new tinnitus masking featured aids. So… ended up with used Opticon Alta 2 ProT miniRITE aids that I understand have that feature. (they are on the way and I have endlessly read everything I could find) Now… have to find what I need to program them. I did find Genie 2 software but need to explore the BTE programmer use and cost. I do find a slowdown in my old brain that is disconcerting but have had strong technical background that may save the day., besides, I am told “if you dont use it…”. Thanks for your posting !
P.S. anyone with suggestions and experience with my new path feel free, I would be grateful.
Are you talking about Oticon hearing aids?
There should be a cable fitting chart in Genie 2. Find your aids in that chart. If your aids are totally wireless you might need the Noahlink Wireless programmer.
I have a serial HiPro too. It has worked great for many years. Recently I bought a Noahlink Wireless, it is the way of the future I believe.
This attachment might help you.
Oops, my old brain is showing 
Well, I guess I need to get price shopping. Someone had said I need another piece of hardware in addition to a Noah. Do you have any idea what they are talking about? (and thanks for the info)
Did you look at the attachment? It is detailed and is a good source for your new aids.
Don’t confuse Noah and the Noahlink Wireless. You do not need Noah.
The Oticon FittingLink should do it no problem for wireless programming.
