Target Gain and Gain

I am trying to better understand some basic concepts about self fitting. I am using Phonak Target 9.0 on my Marvel 70-R .

As I look at Fine Tuning tab, and see for each HA, there are six plots; Target Gain for G50, G65 and G80 and Gain for each of the gains. Regardless of wWhether one uses , NAL NL-2 or Adaptive Phonak Digital, is the desired end result that the fitting formula matches the gains to the target at all points?

What I am trying to accomplish is obtaining the best understanding of speech possible in background noise - elevate speech audio against background noise. My audiogram is posted, but what is not reflected is that my score is 12. I struggle when background noise exceeds 50 db, that means I struggle to hear the cashier who is 3 ft. away in retail/grocery stores. Frustrating!!

My understanding is that the Phonak Lumity and Autosense 5.0 does a better job of suppressing background noise, and I may make a change when Phonak releases the next generation.

TIA

Upwards masking is a huge issue with hearing speech in background noise as previously mentioned.

Very very rare that the first fit is perfect.

Very interesting thread. I’m in the very early days of self-programming, and some of the acronyms you’ve used are beyond my current knowledge, but will watch this with interest. I have some very well programmed P90s, but are self programming some M70s.

Most of my tiny adjustments have been based on what I remember of how he tweaked the settings in my P90s. A lot of what he did was around the compression at the high end of the . I believe he made efforts to compress the loud sounds to help the soft sounds be heard, a bit like your cashier issue. He did say it was very difficult to do, as changing one value, tended to change others as well.

I just decided to experiment by changing my thick tubes and earmoulds for thin tubes and . On changing the settings to reflect the change I was prompted to run the feedback/. As a result of this, the high frequency gains were decimated. My Audio didn’t run this test, for that very reason on the P90s. He dislikes Phonak’s feedback manager, as it’s far too aggressive. I’ll post pictures later of my gains before, and after running it. I’ve not noticed feedback, other than the occasional squeal when running my hand over my ear. My wife can hear when I stream much more though.
