I had some tests today.
When I was assessed for suitability for a CI I scored 37% on a “sentences in quiet” test. That’s when you sit in a soundproofed room, a certain distance from a speaker which plays a recording of a male voice repeating sentences. The volume is set at a specific level. You wear your hearing aids set at their optimum levels.
Today I had several tests and scored:
Sentences in quiet with moderate to loud volume 95%
Sentences in noise with moderate to loud 96%
Sentences in quiet with quiet speech 93%
Male and female voices in quiet 89%
Male and female voices with background noise 52%
Words only, in quiet 72%
Sounds, ie on the right lines but wrong word 88%
You can see the importance of context in understanding speech. A word alone and the score is 72%. Within a sentence the score leaps up to 95%. You can also see the effect of background noise on understanding with a huge drop from 95% to 52%.
One sentence was “The milk is in the pitcher”. I heard “The milk is in the picture” and thought that I hadn’t understood the sentence, why would the milk be in a picture? Then I realised that the word was pitcher. In Britain we would use the word “jug”. Pitcher is used rarely. You can see how you have to be thinking and analysing all the time in order to understand what is being said.
So, a very good visit. Some more volume was added with no other adjustments to the map. I exchanged a cable that connects the word processor to a radio or MP3 thingy as mine doesn’t seem to be working properly. I will try that out sometime.
Oh, and yesterday I had my HA adjusted. The high frequency volumes were moved down so that the sound in that side became more comfortable. That seemed to make an improvement over what I could hear as when I came home I noticed that I could hear the kitten squeak for the first time.
Edited to add this audiogram chart showing my unaided hearing in the right ear, before and after implantation. Very little difference except in the 25o range, so the Med-El Flexsoft electrode does preserve residual hearing.
