Re: Mapping

[Guest guest]

The Nucleus has three strategies to choose from: Speak, CIS, and ACE.

Speak - Spectral peak - this strategy utilizes pitch information from the

sound waves. It is the " slowest " strategy of the three which means that it

needs

less power to work. It is NOT that you hear more slowly. Speak uses up to 20

electrodes and roves all over the electrode array picking up the important

parts of speech.

CIS - Continuous Interleaved Sampling - don't ask me what that means! lol

CIS is the fastest of the strategies and uses timing information from the sound

waves. It only uses a subset number of electrodes that you choose based on

how things sound to you as you try different maps. Some poeple say they like

CIS for music.

ACE - Advanced Combination Encoder - this software takes both pitch and

timing information to deliver sound. This seems to be a very popular strategy!

All in all, there are so many different ways that you can get mapped, that it

is hard NOT to find one you like if you try long enough.

How was that?

Hearing with an implant in noisy situations takes time and practice. We are

fortunate to have software additions that can help us in noise.

Autosensitivity dampens the background din and allows the voices to come

through. Autosens can be found on the 3G and the BWP (body worn processor).

Whisper makes the soft sounds of speech more prominent but is best used in

quiet. We wouldn't want all of the soft speech sounds to be amplified in

background noise. Whisper is only found on the 3G.

ADRO takes both capabilities of Whisper and autosens: it dampens the loud

sounds and raises the soft sounds. I LOVED to use ADRO at the movies!! ADRO is

only on the BWP.

The BWP has a button for everything so we can really play around with all the

settings to get the maximum benefit in any listening situation.

The 3G can only have either a volume map or a sensitivity map but I find the

sensitivity map to function very similarly to autosens. When I lower the

dial, I cut out a lot of far-away sound and leave only the close voices to which

I

am listening.

Mine was changed from autosen to manual sen so i wont have to deal with

autosensitivity works automatically based on the level of sound that is

coming in. a sensitivity map means you can control the sensitivity using the

dial.

if the sounds get louder and you want to cut some more out you would have to

change the dial. with autosens, you let the software do the work for you.

[Guest guest]

think of sensitivity like concentric circles. when you dial down the sens,

you will not hear as much sound from the circles that are furthest away from

you but the circles closest to you would still sound pretty much the same.

however, if you had a volume map then it would lower the volume of all the

circles

around you.

you get 2 program slots on the 3G. you can have both sens maps, both volume

maps, or one of each. the volume remains fixed on a sense map and the sens

remains fixed on a volume map.

my personal experience was that i chose a sens map after my C levels had been

pretty stable for quite some time and didn't feel the need to change settings

a lot. i also liked that the sens map worked better for me in noise. each

person decided what works for them.

Here is an explanation I found on the internet. I can't put it in

better words than this. Alice

The sound heard with the help of the implant is different from the

sound heard with a normal ear. Working on better speech coding

strategies is one research goal. Over the years, Cochlear

researchers have devised speech coding strategies such as SPEAK, and

ACE (Advanced Combination Encoders).

The utility of the speech processor depends on how the sound is coded

and how it delivers the stimuli to the hearing nerve. There are two

ways to perceive pitch: place pitch and rate pitch. In rate pitch,

the rate of stimulation conveys the sound; in place pitch, the

stimulation at a place in the cochlear conveys the sound. In general

it is admitted that at low frequency, rate pitch prevails and at

high frequency place pitch is important.

SPEAK was developed in collaboration with the University of Melbourne

and introduced in 1994. It works by identifying the high intensity

parts of a speech signal and stimulating the appropriate electrodes

with the appropriate energy thus providing both spectral and temporal

information. This approach takes advantage of the 22 electrodes:

pitch relates to the position of the electrode in the cochlear and

loudness on the current intensity level.

Another coding strategy CIS (Continuous Interleaved Sampling) works

on stimulating fewer electrodes but at a fixed high stimulation

rate. This provides good temporal information but the spectral

content of the signal is not represented.

Patients usually choose which coding strategy they want to use. ACE

combines the best features of SPEAK and CIS.

I understand the volume control but can you clarift the sensivity

control? So if you get the sensitivity control you are stuck with one

volume setting. I am getting the 3G. Or can I get 2 programs one

with volume and one with sensivity so I can choose. My audi just

ordered my new Hearing aid for the other ear today the SUMO XP.

Probably have that befor my hookup on the 21st. Got several good

recommendations about that hearing aid working good with the CI

That is correct, you want something you know you can endure over long period

of time,, a short " that enuf " usually is " louder on long run " . For lack of

better word,, you can endure a short headache,, but if it drags on, it get more

bothersome, same idea with your C level.

you only want it " comfortable loud " , not the loudest you can " put up with " .

Evel,

Yep, tones are used to set your low and high levels. This will

probably be done at the next few mappings as the brain adapts.

C & T levels. C Comfort is the maximum you can comfortably

tolerate. T Threshold is the softest you can hear. C & T will be set

for each channel.

Me too, half hour and I am at the clinic. You may want to get

those C levels as high as you can handle since you are new, because

the brain is going to adapt quickly, and you might even find it too

soft by the time you get home. LOL You have much to look forward to.

Does that mean that making yourself used to tolerating louder electrical

mapping somehow affects the IDR 75db (55db sound window)?

I think it would be good if someone know why we should not tolerate a " too

loud " sound and why we should tolerate them...

With hearing aid, the way I see it, if you can hear the louder sound and it

doesn't hurt you, it's better to increase it so that your " dynamic range "

will be better, the compression ratio will be reduced, the quality of sound

will be more natural. I wonder if something similar exist in cochlear

implants.

Be grateful that he did! I am sure there are MANY hearing aid people out

there who would rather take our money then have the professionalism to finally

admit that we can no longer benefit from hearing aids. I was very fortunate to

have had this said to me as well. If it wasn't for my hearing aid woman, who

hardly knew anything about the implant herself, I would never have gone this

route!

I totally agree with this. However, sometimes each individual tone sounds ok

and then when you listen to all the sounds together everything seems too

loud. In that case the audie can just decrease the C levels just a couple of

notches to make everything confortable before you leave the office.

i remember my first week after hookup i was so excited to hear and wanted

more MORE!!!!

so at my next mapping i pushed the high frequency levels i came home to

a week of hell

whenever anyone dropped a fork in the sink i'd like to die those

beautiful bird sounds were horrible if i had a bb gun i would have shot

those

suckers out of the trees this all from pushing levels i learned quick

go as high as comfortable because pushing especially when new can be a

nightmare

[Guest guest]

jerome

the good thing about mapping is each time you go these level change i

kinda think like each time i was mapped my sounds " opened " more the

difference between my C and T on my first mapping wasn't much a very small

difference which i thought i was hearing everything!! over time these

levels widened a great deal for me it took a little more time i guess

because i wasn't used to haveing any auditory input

one good reason why these levels are not pushed beyond tolerance is because

if they were i know i would have never worn the thing doing this

slow but steady allowed me to get used to sounds AND to begin to understand

them if these sounds were LOUD i couldn't

begin to comprehend their meanings
