A question for audiologists and Phonak DYI experts

Hearing Aids
#1

Hi,

I want to translate a modification I’ve made on MyPhonak app into a permanent change affecting all Autosense programs.

In order to pass the right information to my audiologist, I need to know the range of frequencies covered by the treble, bass and mid switches in the equaliser.

In this article here (How Do I Apply My Patient's myPhonak App Adjustments to Their Hearing Aid Settings in Phonak Target?), it says:

  • Bass:** <290 Hz*
  • Middle:** 500-2.5kHz
  • Treble:** >1.5kHz

However, it seems wrong as middle and treble would overlap and there would be a gap veteeeb the bass and the middle.

In general, which frequencies should I mention to the audiologist if I increased the middle switch by two steps (which should correspond to 6 db… can you confirm?) and lowered both treble and and the bass by one step (supposedly corresponding to 1 db each)?

Thanks in advance for your help!

Get her to select 3 channels in the software and then it’ll give you the bass, middle and treble.

So you mean that the audiologist can “condensate“ the channels to just 3 in Target to mimic MyPhonak app interface?

Yes

These are the channels she can select.

Thanks Zebras, you‘re a life saver!

Can you confirm that one step in the equaliser corresponds to 3db? My audiologist isn’t sure about it…

#6

I’m not sure on that one and not sure how I would find out.

Hopefully someone else can help.

One curveball you may encounter is that the Phonak Target software won’t allow these boosts, as its feedback management, just won’t allow it. Even though your alterations haven’t caused feedback, it still does this. It’s very frustrating.

Can I suggest your Audiologist goes into each of the elements of Autosense (Calm Situation, Music, Speech in Noise etc), and reduces WhistleBlock to the minimum you can get away with. In other words, reduce it to a level where feedback will start when you cup your ear, but will stop when you remove your hand.

Another point to look at the the G50, G65 and G80. These are the 3 lines. You may be better pushing for G50 increases.

My notes re your question (info from here):

Graphic interpretations from App to Target:
Each notch on the graphic is +/- 3dB with a max/min of 12dB
Low - <290 Hz
Mid - 500-2.5 KHz
High - >1.5 KHz

Just my 2P.

Thanks Peter, very helfpul, let’s see how target behaves!

How did you assume that each notch would be 3db?

#9

I read it somewhere on here that’s all.

I am the furthest thing from an expert…

A few years back Target would remember changes you made to the aids in different environments. When you hooked up the aids Target would recognize those changes and ask if you wanted to implement those changes.

It has been a few years since messing with hearing aids but the newer ones just might do this too.

Please correct me if I am wrong about this.

Where did you see the reference for 3dB, as I’d be interested in knowing this for sure, personally I wouldn’t think it’d be that much.

Edit: sorry I see it was @PeterH
yeah interesting tho

I‘m not familiar with target as I’m not DYI but my audiologist told me that he can’t read the programs I create with the MyPhonak app…

#14

I have target, and I’ve never seen any of the customised app programs.

#15

Several months back I took some Audeo Lumities and connected to my phone to check this out specifically. I did test box measures with the hearing aids programmed at first fit to a flat loss, presenting the carrot passage with the EQ sliders maximized or minimized. This is my first foray into doing this kind of verification of app settings, but it should help with identifying which frequencies/bands to adjust.

Hi Paul,

Thanks for your contribution.

So, what can we assume out of your tests? I’m confused (and very unfamiliar with Target).

Thanks!

#17

Sorry, forgot to task, what do G50, G65 and G80 mean?

#18

@PaulC

This is extremely interesting.

Thanks.

#19

50dB, 65dB and 80dB.

These are what can be adjusted.

#20

It’s the different gains in your programming.

G50 is quiet sounds under 50dB,
G80 is loud sounds over 80dB and
G65 (I guess) is those inbetween.

Having G80 lower, reduces the loud clattering of life, such as Pool balls smashing together. It just takes the edge off. Boosting G50 helps me hear my softly spoken friends. Compression plays a big part.

To me, this all works well with the “Adaptive Phonak Digital” fitting formula. I’ve tried NAL-NL2, but it seems to suit more profound loss, than mine at present.
