they just amplify all the things I didn't need or want to hear, everything except the voices I did want to hear more clearly, even though they were "tuned" to my audiogram.
End of Daiwa's quote
Hearing aids amplify sound, but they cannot fully restore damaged sound-processing in the inner ear or auditory nerve. Many people with sensorineural hearing loss especially lose clarity/consonants (“s”, “t”, “f”, “sh”), not just volume. That's part of my problem. Background noise often gets amplified along with speech. Restaurants, TV, crowds, dishes clattering, air conditioning, and road noise can overwhelm the brain’s speech filtering. Also, you might have more luck understanding male speech over female because of frequency.
The ones I have from Phonak are really good with S/N because they have AI filtration as well as focusing more in the direction I'm looking. They suppress road noise, too. I asked my audio tech not to improve the male vs. female speech thing but she didn't seem amused. Go figure.
I think I overemphasized the audiogram in this discussion. Mea culpa. There are many brands, and some might be better suited to your needs than others. Many companies allow a trial period, and one probably should shop around...not just for pricing but for specialized features, as well.
I asked my AI to put together a list of features by brand. If anyone's interested, just let me know and I'll forward it to you.
