It took me almost a year to get my Signias where I wanted them to be and currently I can hear in noisy environments quite fine.
BUT, I’m using behind-the-ear Stylettos (7AX), which (as already mentioned) have more microphones.
The modifications that I’ve required are tied to my type of hearing loss (high frequency, extreme slope) and your needs will be most likely different.
I had my fitting algorithm switched from manufacturers default(AXFit/IXFit) to DSLv5, which is better suited for high frequency losses and uses less compression. With this change I can finally hear all the whispery, hushed, tiny noises I’ve been struggling with.
I have just three programs.
- Universal
- Copy of Universal, with all automation and smart stuff turned off
- Musicians (which focuses on fidelity and also has most of processing and automation turned off)
in social settings, even noisy ones, 2 and 3 work best for me.
Number 3 has feedback management turned off, which requires a good fit, usually with earmolds, but for me domes/sleeves are enough.
7AX/IX levels have extended range/bandwidth (10khz+) but it had to be manually pulled up since software and fitting algorithms don’t take it into account.
Environmental processing setting was changed to low (it processes/moves the planes of sound, closer and further from you) meaning that I get more sound from the environment, by default it’s balanced.
Noise management for each programme was set to per band/manual, where it only affects low frequency/rumbly sounds.
I don’t use the “Noisy Environment” programme at all, Instead I just use the Universal one and narrow the cone of focus via the app, which will cut the desired amount of noise out. I found the automatic noise management to be really annoying and ineffective.
And finally I did In-situ testing of my hearing via my hearing aids, with per 1dB accuracy (5dB is the default for hearing tests)
You having them for 3 weeks probably means that they’re still in “acclimatisation mode” which means that they will progressively get louder as to not overwhelm you, before they reach their full potential (the time for it can vary from weeks to months, depending on what your fitter deemed applicable. It can be turned off for more experienced users)
