I’ve just had my 3 month checkup. The first person I saw was my surgeon who is a very happy bunny. All looks good! My internal implant is a little sore along the side of the bump, this turned out to be where it touches the processor. I’ll need to hop along to my opticians and get the arm of my glasses (and sunnies!) adjusted so it doesn’t press against the area behind my ear and weaken the skin.
I then went to see my audiologist. She was also very happy at my progress. I had all my electrodes set again to maximum comfort levels and was given a slight increase in sound. I asked for ClearVoice (high) to be replaced with a normal program with a wider IDR (Input Dynamic Range) of 70 for music. With a wider IDR (explained here), you gain a wider range of sound. For the last two weeks, music has sounded pretty much perfect. When I listen to my iPod with the 70 IDR, it sounds even better, it’s so beautiful that I don’t want to stop listening. If I close my eyes, I can pretend I am hearing in stereo, as I sit enveloped in this wonderful sound that is in-my-face-listen-to-me, full and rich, swirling around my head and making me feeeeel the emotion. Vocals sound normal and some are so beautiful that they make me want to cry. Isn’t this what music’s all about?
I had a hearing test and have improved in the last 2 months so this was great news. The decibel range of zero going down to -30db is considered to be a normal range of hearing for a hearing person (above the red line).

My speech and language therapist tested me on my language comprehension, in the left ear with cochlear implant only. Here’s an updated progress chart from pre-implant through 2 weeks post-implant, to my current 3 month status. I’m aiming to get all speech comprehension scores close to 100%.
Sentences in quiet = Listening to sentences without lipreading
Words in quiet = Listening to single words without lipreading
Lipreading & sound = Lipreading and listening to a speaker’s sentences
Lipreading in quiet = Lipreading a speaker’s sentences with no sound
The biggest change has been my ability to hear sentences in a soundproof booth, it has jumped from 24% with a hearing aid to 43% with a cochlear implant. If I did not have the cochlear implant, this ability would have continued to decline. I have been able to understand some words when listening to my Harry Potter audio book, it’s so exciting when I am able to pick out a bit here and there. It’s hard work, it’s almost like concentrating but trying not to concentrate too hard – like when you look at those magic eye 3D pictures and try to see what’s hidden there. My ability to hear words in quiet hasn’t changed, as this is very difficult to do without context to help.
My lipreading in quiet scores, at 43%, are very high. I spoke to a professor whose area of interest is forensic lipreading, and she said most people would score 5% in lipreading in quiet. Deaf people get to practise lipreading every day of their lives but as there are so many homophenes and unseen phonemes, it is not possible to score 100%. It’s great that I can still lip read well – and thank goodness I can, or I’d be stuffed trying to get through all of this! I’ve been worried that my ability to lipread would decrease as I learn to hear and try to break the habit, but my audie reassures me and academic studies show this is not usually the case. However, some of my implanted friends say they cannot lipread any more, discovered when they run out of battery power and are forced to rely on lipreading. So I don’t really know if I’ll be able to hang onto my lipreading ability.
I have experienced some new sounds in the last month. The beeping as the green man (walk/don’t walk) sign flashes when I cross the road, and I can hear it All The Way Across The Road. Amazing! I went to see a ballet, Swan Lake, at the Royal Albert Hall. This was my first visit to a ballet. I was able to hear the orchestra very well and was surprised to see the ballet dancers enter and exit stage very beautifully and gracefully, but with an incongruously ungraceful THD THUD THUD THUD THUD THUD at the same time! I peeled a banana this morning and was surprised by the loud SSSSSSSSSSS sound it made. I then popped out to the shops and another new sound had me jumping in fright so much so that I almost threw myself into the nearest wall. I heard this very loud and deep roar right behind me, I could almost feel it and it jumped out of nowhere, I didn’t know what it was, and it frightened the crap out of me. I used to be scared of dogs that jumped and barked at me so maybe this is where that fright came from, apart from it being so loud and unexpected. I then saw a Harley Davidson go past, obviously it revved just before it reached me. SHEESH!
Although singing voices sound normal, speaking voices don’t sound normal yet (when people talk to me directly) although they are not far off. I feel as if I am living on Planet Cartoon as people walking past still sound like Minnie Mouse or Donald Duck.
And my shoes squeak all the time! Bah!
