Background:
I was diagnosed with Central-APD based on abnormal test results, and my own extreme difficulty with hearing in any environment with background noise, multiple speakers, distractions or while multitasking. I was tested on APD specific criteria, such as reciting numbers you hear differently in each ear, where my performance was extremely out of range.
I suspect I also have early Ménière’s disease due to recurring episodes of pulsatile tinnitus in either ear, along with a sudden muting of low frequency sounds, but I have no significant losses on my audiogram.
Trial:
I trialed a pair of Phonak M70 for a week, and I noticed the most benefit when decreasing the gain on low frequencies by a large amount when compared to the mids and highs. Along with power domes, this significantly cut the volume of the low frequencies, and I stopped hearing this constant low-frequency hum/babble that seemed to drown out everything else.
Increasing the gain on the frequencies within speech range, so as to be perceived louder than normal, also seemed to increase detail retrieval and clarity. Raising noise and echo cancellation cleaned up the audio well and made it easier to understand. I got so comfortable that after only a couple of hours with this profile, removing them made my ears feel plugged and muted and I was struggling again to hear others.
Purchasing:
I’m considering a top of the line hearing aid, as these seem to have the best features concerning speech processing, echo cancellation, and noise treatment. I’m really only interested in RIC models for the best value for the features available, as well as disliking how BTE earhooks look and their size. This narrows my search to:
Phonak Audeo Paradise p90
Oticon More 1 miniRITE
Signia Pure 7 AX
Starkey Livio/Evolv AI 2400 RIC
Resound One 9
I plan on buying used HAs online off ebay, and being fitted for receivers and domes locally. I’ve checked with audiologists here (I’m in Jordan) and they will fit hearing aids bought elsewhere for fairly low fees. Hearing aids from the manufacturers listed are available to try in-clinic only. I would prefer not to get Widex aids as there doesn’t seem to be an audiologist here that supports them.
