This morning one of my Starkey Halo 2 aids degraded in performance. It still outputs audible sound, but it’s just muffled and not as “loud” as it was before. However, some of the observations rule out what I initially assumed: malfunctioning receiver (I have a custom RIC mould).
-
I do not remember doing anything special with them; when I took them of last night, they worked just fine. The other aid seems to be unaffected, as far as I can tell. I’ve also tried putting in fresh batteries and cleaned the receiver.
-
Interestingly, when I stream audio to the broken aid, it works exactly like it used to. This indicates the actual receiver is performing fine, but the issue is inside the hearing aid itself, when it’s processing outside sound.
-
I used to hear some very quiet “clicking” or “whistling” from he broken aid before, but I never really paid attention to it. Now I hear more audible “clicking” and “crackling” from the aid.
-
Sometimes, the broken aid feels like it’s performing closer to usual state, but it’s fluctuating and perhaps I am just making it up inside my head.
-
I have tried connecting the aids to my programmer and check Starkey’s fitting software if maybe some diagnostic alert pops up. Only an alert about feedback cancellation possibly not working showed up.
-
I also tried updating my targets in an attempt to “reset” a broken memory, but no effect.
-
When I ran the feedback process in the software, the software announced that it failed to measure anything, even though I heard the typical buzzes.
So far, my hypothesis is for some reason the feedback cancellation in the broken ear decided to malfunction and is muffling everything. I do not have a vent hole due to my hearing loss (90dB). This could explain why the hearing aid works fine when I am streaming audio to it, because it isn’t running the feedback cancellation algorithm on streamed audio.
Does anyone have any other ideas about what might be happening here and how I could attempt to fix it? Ironically, last week I had a meeting with a Phonak rep to buy an upgrade, so perhaps Starkey gods decided to punish me for my lack of brand loyalty.
