I got implanted in my worse ear. Would it have made a difference if I implanted in my right? Not really. To me the sounds are coming in my head, so it's not like I can only hear "out of my left", per se.
I'm one of the ones that still have residual hearing. And to be really honest, after a few weeks of activation, everything sounds "normal", just like wearing my hearing aids, but I pick up sounds a lot easier, especially in the high frequency range. Right now I hear everything on the 10db line (so yeah, I have supersonic hearing), and I was told that it's sort of rare for this to happen. While everything sounds natural, i still need tweaking.
I have come to a conclusion that my hearing aids is compared to Bass. I pick up all the low frequency sounds. The only high frequency sounds I heard through my HAs would be female voices, whistles (when people whistle, not hearing aid whistles), that's pretty much it. The CI adds the "treble" part. So, now I can hear the SHH, CH, high pitched sounds, and sounds from a distance that I couldn't hear before, unless if it's right there in my face. So, I could see why some deafies says, "Oh ew! It sounds electronic, staticky, robotic", etc. BUT...I think they don't realize that they're the high frequency sounds that they have never heard before so they're like "WTF?"
To me, I personally feel that anyone who has residual hearing and functioned very well with their hearing aids, but lost their residual hearing for whatever reason, will do a lot better than those who have been deaf their whole life, with low to poor lipreading skills, poor hearing skills. Mind you, I'm making this comment based on 8 other friends who have CI. Only two of us are able to hear very well with our hearing aids prior to CI. The others complained and bitched about how everything sounded so electroinic when they were activated.
SO...based on my comment, it's all on indivdual basis.
Sorry for blah blah blah! I'll be thinking of you on Leap Year!!
