Hi everyone,

Here is a note from my audi followed by my speech discrimination scores as well as my audiogram with and without the electrodes turned off:

"Lisa,

Here are the audiograms you requested. As you can see, you are missing some of the high frequencies now. This is the area which caused the dizziness and nausea.

However, luckily your speech discrimination scores are stable even with them turned off.

Here are the score comparisons:

4/08

HINT - Left CI: 81%
CNC - Left CI: 54%
HINT - Right CI: 97%
CNC - Right CI: 70%

2/11/09

HINT - Left CI: 89%
CNC - Left CI: 34%
HINT- Right CI: 100%
CNC - Right CI: 78%

Let me know if you have any other questions or concerns.

Linda"

Audiogram with all electrodes turned on:

Test Reliability: Good

Left CI

250 Hz - 20 dB
500 Hz - 30 dB
1000 Hz - 30 dB
2000 Hz - 20 dB
4000 Hz - 30 dB
8000 Hz - 30 dB

Right CI

250 Hz - 10 dB
500 Hz - 20 dB
1000 Hz - 20 dB
2000 Hz - 30 dB
4000 Hz - 40 dB
8000 Hz - 40 dB

Audiogram with 6 high frequency electrodes turned off on each CI:

Test Reliability: Good

Left CI

250 Hz - 20 dB
500 Hz - 30 dB
1000 Hz - 20 dB
2000 Hz - 20 dB
4000 Hz - 60 dB
8000 Hz - NR

Right CI

250 Hz - 10 dB
500 Hz - 20 dB
1000 Hz - 30 dB
2000 Hz - 30 dB
4000 Hz - 60 dB
8000 Hz - 70 dB

Hear Again: As evident by my speech discrimination scores, I can understand speech much better now that 6 high frequency electrodes have been turned off on each CI. I LOVE the way I'm hearing and do not plan to have these electrodes reactivated in the future.
 
Hearing in Noise Test

Consonant/Nucleus/Consonant.
 
faire_jour,

The CNC consists of single syllable words while the HINT is made up of 50 sentences that are played in quiet and in noise.
 
Those are good results right? Since I don't understand much of it, apart from the percentage scores <giggle>

I'm soooooooooo glad your dizziness and nausea is gone!!!! <hug>

The HINT scores show she is very smart and able to extraplolate sentences.

CNC are lower because there are not extra cues like in a sentence.

:giggle:

According to my audi, those are very good scores considering how many high frequencies I'm missing.

The recording for the HINT was a male voice. It was very easy for me to hear and understand even in background noise.

By the way, the background noise used in the HINT really isn't that much louder than the male voice.

Then again, that's easy for me to say now that I can hear well with my CIs.

When I wore hearing aids, I couldn't understand any sentences that were played in background noise.

Another special <hug> for your good scores

CNC Test

The Consonant/Nucleus/Consonant (CNC) Test was developed to provide lists of monosyllabic words with equal phonemic distribution across lists with each list exhibiting approximately the same phonemic distribution as the English language (Lehiste & Peterson, 1959). The CNC lists were revised (Peterson & Lehiste, 1962) to eliminate relatively rare words and proper nouns.

The resulting 10 lists of 50 words (500 words total) contain monosyllabic words with a frequency of occurrence greater than four per million, as calculated in the Thorndike and Lorge word frequency tables (Thorndike & Lorge, 1944).

In each of the CNC tests, every word is preceded by the carrier word “Ready.” There are three practice words at the beginning of each list. The words within each list are separated by approximately two seconds of silence on the CD.

HINT means hearing in noise test.

Thanks for your audiogram, hear again.

Howcome your right CI is better? Does the amazing 10db aided at 250Hz have alot to do with it? Also it's amazing your speech comphrension is similar despite having little aided hearing above 2000Hz. No wonder my audiologist didn't recommend any CI for me and just says I need to train my ears and ill improve my speech comphrension. I am still going to get them reprogrammed with max gains and transposition.

I should get 10db aided at 250Hz, 20db at 500Hz, 30db at 1000Hz, 50db at 2000Hz when he's done maxing the gains. He will utilize other features such as transposition, noise cancellation, distortion reduction, etc that should let me hear loud and clear. Of course if my aided/unaided hearing was as poor as yours, hear again I would probably get a CI(or two!) It's no wonder I am surprised anyone with equal or better hearing than me would get a CI when my audiologist can program his HAs to give those people great benefit!

I believe the speech discrimination with my right CI is better because it sounds much clearer to me than my left CI. I also think this has to do with the fact that my left CI is older technology (N24 CI) compared to the Freedom which has been shown to improve speech discrimination significantly compared to the N22 and N24 CIs.

The reason my speech discrimination is similar is because I was listening to a recording of a male voice. I have a much easier time hearing male voices as opposed to female.
 
deafdude,

The only reason why I'm not hearing well above 2K is because 6 high frequency electrodes were turned off. If you opted to have a CI, you may not have that issue.
 
It's all about clarity to me. What is the point of hearing at 10 db if it sounds like someone has just cranked the volume on the mic up? I have heard people speak into a microphone too loud and it is impossible to understand.

That's a good way to describe lack of clarity, faire_jour and seems to be how I hear with my left CI as opposed to my right. My left CI sounds distorted while my right CI does not. When I watch TV or listen to the radio with my left CI only, I have a great deal of difficulty understanding what I'm hearing. If I listen with my right CI or with both, I have no problems at all.
