Thank you for your explanation. It seems to me It’d make more sense if I had that type of experience unaided, whereas that was never a problem. Unaided I only have speech issues in corner cases (deep voices usually with accents or poor enunciation). And now, with aid, I was very lost.
Contrast this with my Audi’s small office where she has air filter, AC, lots of machines, aided I did not have issues speaking to her. Worst case using the auto settings, I could still understand her even though the other noises were overwhelming to deathly loud.
If it matters, my ears have been this way likely since birth, and flagged in kindergarten. In the last 10yrs, when I got tested as an adult, not because I experienced issues, they have been stable. Other than the things mentioned, I have loved my experience aided because it gives me a 3D world/immersive experience which was only possible previously when I cranked up the volume quite a bit. My cello sounds much more beautiful. I don’t want to go back to unaided world.
