I think that fitters don’t do their due diligence of properly fitting aid for the trial. If they didn’t do REM, test you with word recognition and tweak until you got good results, what exactly information you can get from such trial?
If your fitter was like that, then you can trial it for a months and still not have a clue if that device would work for you.
On the other hand, if your first fit was 2h long with all measurements before and during the fit and you left with ability to understand, then you can see how the aid will work in your everyday situation.
And yes, additional fits will help to adjust HA to your needs.
But point of wearing it at home isn’t to decide if it’s powerful enough for you, that should be found out at the office and you shouldn’t even go out of there with aid that can’t give you what you need.
Your wants are checked through trialing, but your needs should be met from the first fit. Why on earth would fitter fit you with not enough powerful aid and let you go out?
Ability of aid isn’t determined by chart from manufacturer (only) but through the verification with you, eg adjusting aids until speech recognition is satisfactory to you.
To me your experience sounds like your fitter doesn’t have a clue how to do proper fit and therefore trialing. Or what’s the purpose of both.
That doesn’t have anything with you or your experience in wearing hearing aids. We shouldn’t be pushed to self adjusting / diy if fitters would do proper professional work in the first place.
I trialed phonak marvel m70 twice. First time, with nice guy but I concluded that I’m better on my own. Then finally I found someone doing proper measurements and fitting, and oh boy, same device, same custom mold and insanely different results. With first (and we did spend some time ‘adjusting’ it by ‘how do you hear me now’ method) I couldn’t understand everything said on TV 2m from me. Anything more complex was a failure. Keep in mind, I have one good ear, so that means that signal coming out of the HA for another ear was so useless that it killed my brain’s ability to recognise speech.
Two weeks after I gave back the aid, I got new one, same device, but proper fit. Not only I don’t need to watch tv to hear it (on average), but for the first time I could understand my hubby speaking from my bad side, while we were in a busy parking garage of a shopping centre.
Same device, insanely different fitting procedures, and insanely different results.
So, if you like device features, try it with some better fitter. Even if it’s 2h away, you won’t probably need so many visits as you’ll need with a bad fitter. Like, 1-3 (2h) visits could be enough for good fit, unless your environment needs are complicated.
As to autosense on marvels, someone mentioned it can be adjusted even when it will switch. And yes, you have only 3 completely customisable programs. Like almost different audiograms customisable, I mean, you can impact all frequencies, not just turning on and off of special features like noise reduction etc.
However with the app, you can adjust each program on the fly (which focus, bass/middle/trebble, noise cancelling, volume of course, decrease loud-increase soft) and save it if you want. I don’t know the limit there, but also, you don’t have to save it, if you need it just once.
However, you have to manually switch back to autosense when you’re done. That part I forget
Oh and my new audi said that his goal is that I don’t need the app adjustments for my usual every day needs. Plus good speech recognition score.
However I do have moderate-profound or something reverse slope hearing loss aka low frequencies are dead which is very hard to fit. And by my short experience with several fitters in my life, all but one had no clue how to approach it so that I can get nice results.
I thought that it wasn’t possible for me to get good speech understanding, but only stereo sound. That’s how bad previous ones are
