After a welcome and some introductions with the audiologist, I was handed my shiny new processor (the bit for the outside of my head) in Bordeaux Red and hooked up to her computer. The switch on took about an hour, and unlike the name suggests, involved more than just a simple flick of a switch.
The implant cable which now sits inside my cochlea has 12 electrodes, which you can see if you look carefully at my x-ray image. Each of these electrodes is responsible for a different set of sound frequencies, ranging from high to low tones. The switch on process involves adjusting each electrode in turn, to produce a comfortable range of high and low volumes.
"Ouch!!!!" was my first reaction when I was connected to the computer. I felt a loud, uncomfortable crash inside my head. My instant reaction was to rip the processor off my head. But I resisted, and the sound faded away. The session continued like this for about 30 minutes, using the computer to throw different tones at different volumes at my implant - the quiet ones were fine, the louder ones brought tears to my eyes.
Walking back to the car, I felt nothing but exhaustion. When we got home, there were so many sounds coming from everywhere and after an hour, I pulled the processor off, and wondered how it was going to work. I'll be honest, I wasn't expecting it to be quite like this.
While not pleasant and consistently uncomfortable, this reaction is typical, so I'm assured. My brain will take time to adapt. But at the moment, it feels like there's an awful lot of adjustment to be made.
