after doing more research I don’t think that signia makes a hearing aid as powerful as the Phonak Naida B. I may also consider the oticon xceed.
Regarding REM, how big is the microphone that goes in before the ear mold. The last time an audiologist tried to make an ear mold for her — three tries — there was so much feedback I began making her molds using earplugs that work much better. But I also make them so the tube comes very close to the eardrum which greatly helps her.
I wonder if there’s room for a microphone between this custom mold and the eardrum. and right now she’s at maximum volume anyway so I wonder if REM would really make any difference.
