Hybrid "products" Hearing Aids & Cochlear Implant don't appear to make much sense. Dealing with different conditions, Deafness is not the same as having some problem with hearing.
Depends on how you look at it. If you are a true candidate for a hybrid then you are both HoH AND deaf. Deaf in the frequencies to be implanted, HoH in the frequencies to be aided. While SoundRecover is a great first step to allow people with steeply sloping losses to perceive high frequency sounds, it makes a mess of
how they perceive it. If you are a musician then being able to hear in low frequencies and being deaf in high frequencies doesn't get you anywhere because you need to be able to hear exactly what you need to hear, not compressed, not distorted, not with bits missing. I think that is a comment based on the way we understand implants to be now, not the way we could understand the development of implant technology - if people have a profound loss but it's only across half of the audiogram why go to a special effort to exclude them from the technology because it's "Not for the Likes of Them"?
I have to presume there is a market for the product or it wouldn't be for sale. I don't think companies are looking for ways to spend money on unmarketable ventures in this economy, and ski-slope is one of the most common audiograms. One of the features they must address in the clinical trial data is the effect of repeat implant surgery if the person has a deterioration in hearing in future. Reasonably stable hearing is a requirement for candidacy, but the possibility has to be addresse.
I'm not currently an implant candidate, hybrid or otherwise, because of my high frequency "hearing". It's not usable hearing because it distorts and hurts and gives me crazy tinnitus and vertigo so it's clipped off using SoundRecover to avoid exposure. They would not allow me to voluntarily destroy that "hearing" in exchange for potentially usable hearing from an implant, but I'm interested in the progress of selective frequency implants. This is the easiest audiogram to hybrid, and it may never be possible to do any other such as reverse slopes becuase the high frequency is in the first turn of the cochlear. My dead area is a bit further down, but as my loss changes and progresses and technology moves forward there may be something in the pipeline. I know a lot of people with the right profile for a hybrid implant, though, and I'm interested on their behalf also.
I'm interested in the possibilities for a range of purposes, they recently reprogrammed a CI to use it to stablise balance in a patient with severe vertigo from Menieres. It's very, very early days of trials, but that's a huge development of the technology to use it for something totally unrelated to hearing.
