I talked to another lady who got CIs(two) and she got lucky, especially in the "worse" ear that had 95-110db loss. She now hears 15-25db thresholds and was so happy she got her better ear implanted. I was worried she would hear worse than her HAs since her better ear had only 85db-95db loss(250Hz to 8000Hz) The Phonak Naida V UP HA's have a max gain of 82db so she would be hearing around 10-15db with those HAs at some frequencies. Yet she says she not only hears speech but also hears environmental sounds better with either of her two CIs! I am trying to understand how that's possible compared to the best HAs. She did say that her "better" ear had some cochlear ossification which was only discovered during surgury. Perhaps this could be a plausible explanation of why she was hearing unusually poor with her HA. I feel I am hearing quite decent with my HAs.
I for one hear a great deal of environmental sounds and my hearing is actually worse than hers except in the low frequencies(75db loss at 250Hz for example) I do know that anyone considering CI should be getting a 90 day trial of the best HAs first. Not to do this is very irresponsible, sadly ive seen a few people get CI without ever trying proper HAs or getting their HAs properly programmed. They have no idea what HAs could have given but with their residual hearing, the results could have been great!
I do know that it's easier to achieve an improvement in speech comphrension since getting the same thresholds with CIs does yield an improvement over HAs but for environmental sounds, it should be the same. My audiologist is going to reprogram my HAs two weeks from now and he should get me down to 10-15db in the low frequencies and around 30db in the mids. Transposition should give me access to the highs by shifting them down to the mids. To be fair, I won't count transposition in any of the math I have done and will do. So therefore ill count it as missing frequencies above 2000Hz entirely.
Transposition will make a 4000Hz sound appear to sound like a 2000Hz sound, one which I can still hear. No HA will give me a real 4000Hz sound since I have no residual hearing in the highs that can be amplified. Oh well ive mentioned before that high frequencies 2000Hz and above only account for 5% of environmental sounds and many people find high pitches annoying to hear. Even my parents say I am not missing out by not hearing high frequencies. I am able to understand 80% of what my dad says without lip reading. It could be 90% after my HAs get reprogrammed. I also mentioned that this profoundly deaf man scored over 90% on speech. I am saying get proper HAs, find an expert audiologist that will program your HAs to the max and give your HAs a chance to shine!
She did tell me that a good surgeon knows how to properly implant the electrodes and won't rush the operation. That could be part of the reason, that and she said she's in the top 2% for CI results. In other words she also got very lucky to have such a good CI result. Her thresholds look impressive as well as her speech comphrension. I am happy for her but caution others to be realistic in their CI expectations. I am realistic and to be honest, I am not expecting CI to give me hearing as good as my HAs so of course im not getting CI till technology improves alot more and my hearing gets worse. You can see my previous posts below for more information and the math ive done.
