Phonak Target Tweaks, Tips, Techniques, Troubles and Thoughts!

Another Target Fitting question to help understand concepts better.
I just decided to try NAL 2 again. Was unable to totally overcome annoying sibilance especially in the left ear, with the DSL-V5.

So this is a reset fitting, to target with the NAL 2
I raised all levels by 3dB both ears equally just because the default seemed very low in calm, tv and phone. I raised the levels in those three modes.

But look at the graphs. Why don’t the left and right themselves, coincide the audiogram curve more? Why does the dip coinciding with better hearing, not align with the audiogram for each ear?
Also - why are the Media and Phone specifically different curves at some points.

Can someone please help me to understand the theories on this?

Different formula gives different results so each program has a different curve obviously, but isn’t there an “autorelate” feature in target so the programs are more aligned, can’t you make exact copies of them, try clicking on the “options” AutoSence is weird, I never liked it.

I understand that each formula, would have a different curve. For example the NAL has much more compression, than the DSL
BUT the three graphs here are all for the NAL new profile.
See the comparative curves left and right, where my hearing dips don’t seem to corelate as I would have expected with the fitting. Why?

Also why are the phone and TV so different… what is the logic on that difference.
Just think we could learn from this.

There’s is many factors, which were considered by NAL-NL2 creators, below there are surely two of them:

Equal-loudness contour3

An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing frequencies are said to have equal-loudness level measured in phons if they are perceived as equally loud by the average young person without significant hea

and:

Also see the “Gain” screen and check the feedback threshold and the maximum possible output by your particular receivers - they may be limiters.

By the way, do you have to have quite high compression ratios?

Low compression I find painful or distracting. I think somewhere around1.8 - 2.4 is more comfortable in most frequencies. But I am just guessing from poor memory this moment.

Allright, indeed, it can be. It is highly individual.

Just seen this thread, very interesting. I saw somewhere that the new Infinio Virto uses Autosense 7.0

With this in mind, perhaps a firmware update will appear for the earlier ones in due course?

Regarding earlier posts, I concentrate on Music and Calm the get the the curves similar. I’ll alter the Bluetooth curves (speech/music) to get them close to each other, and similar in volume to the others. I generally spend more time with the sliders in Program options, than anywhere else.

Also - under what circumstances should the Fourth tic box be checked to RESET PROGRAM OPTIONS. I assume those are like the noise settings and the microphone angles etc.

If you change something like you molds or fitting programme, the box will come up with this 4th option unticked. If you tick that box, it will reset all the elements to their defaults. For example, you may have altered your sliders in Calm situation, or music. Leaving it unchecked leaves your changes as they were

I been away too long….been listening instead of reading.
Promise to catch up on missed posts…ASAP.

Meanwhile, need to replace my iPhone 12Pro Max. What phone of any type - do phonak sphere users find super great and compatible. Is there any great user experience ?

Currently, wind noise is a problem for the other person to hear me.

All environmental noise is an issue, you’ll never be able to make it better unless your in a quiet place, your better off using your phone as a..well a phone, work’s perfectly this way, maybe in the future AI will somehow work this out.

normally, one speaks into the mic end of the phone, and the phone can be held to shield the built in mic from the direction of wind. But with the Phonak’s and iPhones, as been discussed on this forum, the phone’s mic is disconnected with BT connection to the HAs. So the exposed mics on your instruments - right out in the wind, get the street noise, before your voice.
Thought I read how Android’s are different.
Can someone confirm this and suggest a better phone match to the Phonak Spheres, than the iPhone ?

My personal experience is that iPhone connect better with Oticon due “MFI”. Phonak connect better with Android phones.

iPhone and Android both use the Phonak HA Mic for phone calls, unfortunately.

This was on the update for Target V11.0 but we can’t work out what it means and where IN Target you disabled hands free calls.
