It seems some audiologists do not like to enter the acoustic code for the molds. Is that because Target will then give warnings if the molds are changed in the future? I suppose with there’s no point in the acoustic code?

Yeah i didn’t ask why my audiologist not entered the acoustic code and the wire lenght.
Maybe because the fitting software are conservative ? so it’s may allow to get the most amplification as possible ?

The wire length is likely just for reference. This explains a little more about the acoustic code: When it comes to acoustic vents, size does matter! | Audiology Blog1 but it does not make it clear as to whether makes entering the code irrelevant. I assume it does as REM will check targets accounting for the venting.

Doesn’t make any difference, it’s a reference thing, you just enter the vent sizing from the drop down menu.

I’m not sure how many audiologists could figure out the vent size of a AOV designed by Phonak and then pick the closest vent option from a limited list.
I suppose the same question taken to an extreme is if one picks the wrong vent size and then performs , does the incorrect venting selection matter?

Yes your correct in they won’t actually need to randomly do this, as it’s all worked out and based on a number of different things including the formula being used etc, yep having say a 0.9mm vent and then entering 2.0mm is obviously going to make a difference, it won’t happen as the vent size would be known after being made right and sent back to the audiologist, if I remember the drop down menu is in steps, as in say 0.9 to 1.2mm and so on, so I guess what happens if it’s 1.1mm or whatever, I wonder how would target would even know? AOV is supposed to take all the hard work ( guess work?) for the audiologist, but when I had mine done it was like 0.9 or 1.0 and no way was it correct, 1.6mm is what i ended up with.

I’m going to be experimenting with a third party mold and none of the fitting software options match. If I have done it probably will not matter. If I do in-situ only, is there a way to optimize for a vent size that is not selectable?

The UP one it’s there without anything … sadly i realised the next day that someting where wrong
Why he has given you so large vent? If you have hearing loss that severe, you shouldn’t have vent at all, especially when you have problem with feedback.
There is my insertion gain and output with Sphere 90 with cShell UP 0.9mm vent:
If you receive new cShell with no vent, I would ask your audi about trying with more gainin high frequencies.
