I’m not sure what your audi means by this. In the Oticon Genie 2 software that controls the Oticon settings, there’s really no “compression” value that your audi can simply DIRECTLY just “turns on or off”. At least not that I’m aware of.

If you look at the screenshot below for the Genie 2 Fine Tuning page for an example MyMusic program, it shows the gains at each of the frequency handle for Soft, Medium and Loud, and the CR (Compression Ratio) in between the 3 gain values for each frequency handle. The gains are adjustable, but the Compression Ratio (CR) is NOT adjustable, it’s just a resulting value based on how your gains are prescribed by Genie 2 based on your and fitting selections and personal profiles and features, etc.

So my question to your audi is, if CR cannot be directly adjusted, how was he able to “turn off” the compression??? By the way, turn off here simply means change it to 1.0 → no compression. The only way to do it is not by changing the value of the compression ratio because it’s not adjustable. The only way to change it is by changing the value of gain of one loudness knee point with respect to the other in the same frequency band. But note that if you BLINDLY just change your gain values simply to get a CR result of 1, you’ll in no time TOTALLY modify/destroy your (carefully prescribed by Genie 2) gain curves for Soft, Medium and Loud.

The MyMusic program is already designed to achieve minimal compression ratios as much as possible, but it doesn’t mean that Genie 2 can simply “turn it off” completely and totally. Now if you’re a (like @flashb1024 ) who doesn’t like his MyMusic gains setting, you can go in there and methodically experiment with changing your gain curves to your liking until you achieve what you’re looking for. But that doesn’t mean that all his CR values end up being exactly at 1.0 (correct me if I’m wrong, @flashb1024 ). So if you’re not a DIY, then you can work with your audi to methodically experiment with your Fine Tuning gain curves for the MyMusic program to make it sound better for you. But don’t just accept your audi’s comment that he’s already turned off all compression for you in MyMusic because as far as I can tell, the Compression Ratio in Genie 2 is NOT editable DIRECTLY.

Below is a link to a thread a couple of years ago that discusses compression, if you’re interested in trying to understand better what compression is and how it helps, and why it’s not simply a parameter that one can willy nilly turn on or off without taking many different other parameters into consideration. In this thread, the audi simply blamed his client’s issue (left ear performance sounds flat) on “bad compression” done by Oticon in the left ear adjustment. I think that was a gross generalization of blame, and I asked the OP to get the Fine Tuning print out from his audi to confirms whether it’s really due to “bad” compression like his audi said or not. I never heard back about that, though.

Oticon and Compression question
A few years ago, I bought Resound 3d Hearing aids and had nothing but problems with them, despite being relatively happy with my previous Resound hearing aid. So I bought the Oticon Opn 1 hearing aids and abandoned the Resound 3d and will probably never go back to Resound as I have found Oticon far better for me in noisy environments. You can view my previous lengthy posts on the Oticon as well as my hearing chart to get some idea of the initial problems that I had with them and how they were …

@Volusiano: Exactly, Mr V…Exactly! (bring back memories??)
Quite right, we have no way to alter compression ratios.
The 1st iteration of the OPN platform using the older Genie fitting software did have that ability.
Oticon developed the original music program, and felt the default provided the proper compression levels, so they disabled programmable compression.
Now, with the More MyMusic debacle, the powers that be deermed it essential to institute the Harmon Curve for MyMusic, because they found 70% of the people they interviewed preferred the emphasized bass & treble of the Harmon.
Of course, the 30% who don’t agree are left to their own devices.
Hence, for me.
Anyway, back on track, @Volusiano next time you take a screenshot of your MyMusic fitting graph, could you click on the “” icon?
That’ll bring up the separate plotting for Soft/Moderate/Loud curves, and you’ll see how Oticon shaped the program.
Luckily it can be tweaked, but you will induce a bit more compression, but also achieve more “Air”
I don’t even know where I’m going with this, so Later!

Thanks, that’s a good tip I learned from you today, @flashb1024 ! It sure gives a nice visual graphical representation of the curves to look at. Pictures are worth a thousand words (I mean numbers) here!
