6 months post switch-on - Cochlear Implant Review

It's now been six months since I was switched on with my third Cochlear Implant. Things are finally starting to go back to what I was used to with my first one, which worked well for 15 years before failing.

My results this time were this..

HINT (open set) Sentences at 3 months: 100%
HINT (open set) Sentences at 6 months: 98%

In background noise +10db SNR at 3 months: 92%
In Background noise +10db SNR at 6 months: 96%

In background noise +5db SNR at 3 months: 24%
In background noise +5db SNR at 6 months: 47%

CNC Words Alone at 3 months: 63%
CNC Words Alone at 6 months: 65%

CNC Words Alone Phonemes at 3 months: 82%
CNC Words Alone Phonemes at 6 moths: 83%

pretty much the same, except a big improvement in background noise, although at one month post switch on that 47% was actually 86% so for some reason I did better back at one month.

I have been practising a lot though. I've been getting audio books out from the library and listening to them - about two per month. At first I needed the book to follow along, but now I don't need that and can just listen to the book while working on photographs. I have to keep listening though, as it's so easy sometimes for my attention to wander and then I get totally lost and have to go back.

I've also bought and borrowed CD's of New Zealand Birdsong. I've been listening to those and relearning the sounds. I used to know them all with my original implant, and they're slowly coming back to me. It has paid off as I was out walking in the country on Saturday and I recognised the bellbirds. So I was thrilled.

I'm finally doing better with the TV as well. I can understand some without text and without the TV cable. With the TV Cable I can follow a TV program well without captions. Still - it's hard work - something to do with the way sound is compressed for the TV. I much prefer captions, but not everything is captioned here in New Zealand, and my last house sitting job had a TV with no captioning ability. In some ways that was good as I was then forced to use and listen without them, and I think that went some way in improving it.

Practise makes perfect.

Great job! Did you get any more recent audiograms with your CI? I remember you as the record holder who was hearing at 0db in some frequencies! It's no surprise your speech is so good :)
