CI-activation log no. 4 – day 5 – Initial shakedown

Wow, what a week! I’m very tired now, but need to put some impressions onto writing…

Have already had many CI-moments, here are the ones I remember now:

  • the dogs at my mom; when they walk on the hardwood floor they give off a ticking sound for every step. I can detect them moving with sound only!
  • I can detect the chorus in rock songs that I know well; like “Girls, girls, girls” by Mötley Crüe (I also hear the motorcycle revving in the beginning!)
  • I detect my son singing in the car while the window is open
  • Jingling of my key-chain
  • I hear mobile phones ringing in TV-shows (never heard that before, ever!)
  • I could detect my sons heavy breathing in the car (he had just been running, racing me to see how far he can get from the garage before I catch up with him, I have to wait for the gate to open first)
  • I detect the difference between –s and –sh

I10-85-cochlea2 All sounds are very thin, high pitchy. That is due to the fact that my hearing residue before the operation all were located in the innermost curves of my cochlea. (from 1500 Hz to 200 Hz in the diagram on the left) That’s where the bass is. The entire frequency range that my hearing aids could amplify, and the vibrations the hair cells were able to pick up, were dealt with by the hair cells in that that innermost curve. (Because of the limited number of remaining hair cells in the outermost areas, I experienced recruitment.)
Now, all those frequencies go to the previously almost dead outer areas of my cochlea (20 000 Hz to 1500 Hz). Which used to be the medium and high pitch range of sound vibrations were picked up by hair cells. Because of this radical relocation of sound information in my cochlea, my brain has to rewire all the frequencies through neurons forming new permanent pathways to the old brain-recipients cells who did the actual “hearing”. Until that rewiring has completed, it will continue to sound high pitched and heliumish.

I wonder if the brain would be able to do the job by itself without the aid of any other senses? Now I’m telling my brain what sounds should go in there when I drive the car, or listen to that rock music, or hear my sons voice. Because I SEE the sounds. But what if I did not see anything, just had to figure out the sounds? I’m thinking my brain probably works both ways, some sounds it’s rewiring by itself, some are helped by my thoughts… Anyone with insight into how this process might work?

As I stated in the beginning, I’m really tired! Today I had a 4 – 5 hour period where I did nothing active… (very unusual for me) Last night my son snuck into my bed behind my back without me noticing it before it was too late (he had fallen asleep). That’s never happened before. Usually I have a very sharp sense of sight, detecting any movement very fast.

All kids are really great about my CI. They fancy the magnet and think it’s way cool🙂

The first 3 days of my CI-life, I suspect I was high on adrenaline. Everything seemed more crisp and sharp. Now I’m almost like I was before I got activated. Dead tired, numb in my bran (just not as “muddy”) and with some psychological reactions, especially very sensitive to any stress, which gives me this tremendous tinnitus again, only now it’s in both ears, and it’s has changed quality in my implanted ear… more low frequency than before, or it’s just my brain who has already started rewiring? Where does the tinnitus come from? Auditory hair cells in cochlea who are trapped in an eternal death scream, or is it from my brain which screams for those frequencies, and when it gets nothing it creates it by it’s own?

I have been avoiding the issue of tinnitus, partly because it’s has been my strategy, to ignore it away and to death, and that has worked quite well… If the tinnitus thing continues now after the CI-implant, I will have to read up on the issue… And I’m afraid the tinnitus on my left ear will take over the job since my right ear now gets plentiful of audio information….

I listen to TV-shows and movies with both the CI and the hearing aid most of the time, sometimes I turn off my hearing aid for a while. While I drive the car I only use CI, since I get too much recruitment from the hearing aid ear. While I’m walking around in shops, ore doing daily chores, I use only CI.

I need the hearing aid to communicate to everybody.

    Everything sounds different at this moment, is to learn to hear with the IC for more excited than you are, a fan of sounds is gone opening slowly and when less to wait you are run over by an emotion and in such a way! You are again child to explore the world auditory, will detail the detail, noise the noise and finally word the word. I taste in such a way of the sound of the wind, the voices of the small children, the sea and finally music although to be perfect it does not have rhythm.

    Good discoveries!
