Re: Sound Localization with CI

[Guest guest]

,

When I am out and about, while I dont put much effort into it,

when I'm waiting for the bus, I listen. I jsut could not do it with

the CI alone. Just about every bloody lighted intersection has

different patterns. Not only that, because more and more controlled

intersections base changes on traffic volume, when there is little

traffic, the pattern again changes. Then there is the infamous right

turn on red. You may not always hear the vehicle there until it

moves. The drivers WILL go for it if you aint crossing as soon as the

light is green. That aint the law, but of course, they dont care.

You cannot easily get a fix on sound that is moving. If its

stationary, yes, you can turn your head and get a fix on it.

Oh one thing I can do at the controlled intersections. If traffic

is consistent, I can tell there is a change in the lights because

there is a momentary lull.

You're not kidding about how difficult certain intersections are to cross!

We have just about every kind you can think of in the neighborhood where I

live. T-intersections, 4-way stops, lighted intersections, winding roads

with no sidewalks and a busy 4-lane highway.

One of the benefits I can see to using a CI and HA is the fact that I'll be

hearing sound from my left. As it is now, I only hear sound on my right

which means that I don't hear turning traffic. Whenever I travel, I always

make sure that parallel traffic is on my right. When this isn't possible, I

use a cane in my other hand (held at waist level) for added identification.

I try to limit my travel to the quiet residential streets in my neighborhood

but even then, I've had a few close calls.

Its scary to travel these days and I have a little bit of vision.

Maybe that is why, I can SEE how crazy the drivers are. LOL I'm near

two 4 lane highways.. Both have buses I use often. Whats neat is

that the highways come really close in parallel so its almost like two

bus routes that serve double duty. Whats bad is there is a freight

train line between the two. Not bad as far as Gimlet goes, she got

excited the first time one passed by just 20 feet away. Rumble

rumble. LOL But when they are playing trains down the line it messes

up the traffic pattern on one of the intersections and there would be

no way you could tell who is going which way. I had to wait it out

for about 15 minutes until the boys stopped playing, and they never

did run a train thru that intersection that time. Sheesh.

You asked some good questions. Like , I rely on the momentary lulls

between lights to determine when to cross, plus turning my CI in the

direction of the parallel traffic to determine if there is movement. I have

a harder time with with localization of voices. Much of the time when I

assume a person is in front of me, it turns out he/she is behind me.

You can still localize sound with HA and CI. Though you will have to spend

time practicing again, because the sound ratio you get from HA and CI will

be different from HA and HA. Still, it's possible.

[Guest guest]

Jerome,

That's what I don't understand. If the sound I'm getting from the CI is

greater than the sound I get from my HA, how do I determine where sound is

coming from? Perhaps the CI audi would help equalize the sound I get in both

CI and HA to help make this easier? Guess I'll have to wait and find out!

One thing I do know is that it will be *wonderful* to hear sound on my left

side again. Even if I get minimal sound on my right with a HA, it will be so

much better than what I experience right now.

[Guest guest]

You can do it once your brain get adjusted to the new sound ratio. Just like

how we do with hearing aids. We have one ear better and one ear worse, they

are not equal, but still, we were able to localize sound isn't it? But it

won't be instant since your brain have to adapt to the new sound ratios....

[Guest guest]

Jerome,

Ever since I experienced a 20 dB difference in both ears, I have more

trouble localizing sound. In fact, I don't hear much of anything in my left

ear. However, when my hearing loss was more symmetrical three years ago,

sound localization was much easier.

[Guest guest]

I do have that much difference in 2000 hertz frequency of my hearing, but

only 10 to 15db on other frequencies.

Wouldn't be fair to compare our experience totally since I rely a lot on my

vision for communication. Regarding sound localization in *my* experience, I

get used to the sound ratio of my existing hearing when the sound is in

front, then I will notice the difference in loudness when it's not in front

like when it's on the side, that's how I tell it...

Maybe if your CI turned out very good you might want another one like most

of the members here.

recently i have participated in a research study on sound localization

i am bilateral

basically for this study i sat in a large audio booth facing 7 speakers

in a semi circle

i was to sit facing forward and listen to a simple sentence then

selective the number speaker i thought the sound came from i first did this

with both CI and scored very well

at times i would select speaker 7 instead of the one right next to it

6 but i knew without a doubt where the sound came from

with just one CI i was really surprised .... it sounded like all sounds came

from just one speaker

i honestly couldn't tell when the sounds came from the left or right or

dead ahead

i had thought if the sounds were louder it meant closer to the CI side but i

was wrong

i was shock to see for myself just how i didn't have a clue what speaker the

sounds came from

i also did something where i listen to a statement like " blue 7 " and

pressed in what i heard on this control gadget this sound was coming from

right in front then another voice saying a different statement was added

and i had to concentrate on the directions this was hard this

was done using both CI and then one then the direction statement was said

in the speaker right in front while adding another voice saying something

different using a speaker to my far left was added and i was just using my right

CI i could understand the speaker right in front a lot easier

with one CI but ..... i realized that what was going on on my left was more

or less lost

it was like this voice on my left was just a minor if that blur scary

to know so much sounds were not coming in

being blind i would guess that the more sounds all around would be better,

safer!!!

Do most people have 2 CI's ? I've usually seen just one. If just one, which

side is it usually on, or is there a " usual " ?

=) Vicki

[Guest guest]

Vicki,

Some do have 2 cochlear implants. You're right, most of people do have only

one. Usually, they have it on right, but some people have it on left. It is

depends on their hearing loss on one ear's side.

[Guest guest]

Hi Vicki,

Yes, some people are fortunate enough to be able to get two implants

(bilateral) but much depends on their insurance company and their ci

center's willingness to do two implants.

There is no " usual side " this is a decision made between the dr and

the implant recipient. Some dr's prefer to implant the worst ear,

some prefer to implant the ear that has had the most recent

stimulation. If the ears are pretty much equal in terms of hearing

loss, the ci recipient generally has a choice of which ear to go

with..This is the case with me..I chose my left ear because I am

usually the passenger in a vehicle and having my left ear implanted

allows me to converse with the driver and other occupants easier..

not so much wind noise if the window is down, however,anyone can get

a longer cable and rest the processor on the opposite ear too.

Hope this helps some

Hugs,

My audie had talked of doing a similar experiment with me. Interesting to

hear your experience. Using only one CI, I know I understand my computer

speech better when I face the computer as opposed to turning my head to the

left or right. The same is true when I add the HA, but my understanding when

my head is turned to the left or right is better with HA than without HA.

Jerome,

If I make good progress with a CI in my left ear, perhaps my CI team will

consider this. At least for now, I have useful hearing in my right ear but

if it continues to decrease within the next year or so, I'll definitely give

serious thought to getting another implant.

[Guest guest]

Thanks - really appreciate that information. =) Vicki

Dear Jerome and ,

My evaluation for the cochlear is coming up on July 2nd. I hope I fail

the word and sentence test.

, I tried to send a message congratulating you but I got " blackholed

sender list " data format error. Congratulations anyway!! Larry

[Guest guest]

I wouldn't mind getting a high score in those tests *if* they can make an HA

that will make me hear very well in the real world. But if not, I hope I

fail too... Haha...

[Guest guest]

We will probably know after your implantation.

[Guest guest]

Jerome,

During my CI evaluation, I tried very hard to hear what I could even though

the purpose of the evaluation was to determine what I *couldn't* hear.

Before my hearing and speech tests began, the audi told me that even if I

couldn't understand a word or sentence, I should tell her what I think I

heard and pronounce the respective word/sentence the best I could.

Unfortunately, I couldn't even begin to venture a guess on some of the word

and sentence tests because with my left ear everything sounded distorted and

with my right ear, all I could hear were vowels. When it came to the hearing

in noise test, I couldn't hear the voice of whoever was speaking.

I wonder if there's a way for the audi to determine whether a person is

cheating? Why someone would want to cheat is beyond me but I'm sure it's

been done before.

[Guest guest]

Hi Jerome and ,

I haven't cheated on hearing tests before but I can understand why

someone might want to cheat on a ci test especially if they ar on the ci

list. I would like to have a ci but I realize that my hearing will not come

back with the flip of the switch by the good doctor. It will take a lot of

hard and sometimes excruciatingly painful work to attain that goal. My audi

told me they would probably not have hair implantation in my lifetime but in

1976 the head of ibm said there was no reason a person would want to own a

computer in their home. Larry

[Guest guest]

Jerome,

Believe it or not, during my CI evaluation, I *wanted* to perform well.

Aside from being a person who doesn't like to fail <smile>, I have vivid

memories of an audi I used to work with a long time ago. He was fresh out of

college and a real " know-it-all. " He tested my hearing and my audiogram

indicated that I had a severe/severe to profound hearing loss. During the

audiogram, he kept telling me to concetrate harder. (Concentrate harder??

Excuse me? How much harder can I concentrate when I have a splitting

headache? Ugh!)

After the hearing test, he discussed the results with me insisting that it

*couldn't* be possible for me to have a severe/severe to profound loss

because my last audiogram (taken a few years earlier) indicated a moderate

to severe loss. He wasn't convinced, so he gave me 3 separate hearing tests.

(I can understand him giving me 2 more for comparison, but 3??)

All 3 tests indicated the same results -- a severe/severe to profound

hearing loss. I had alot of different emotions running through my head. I

was confused. Even though the audiogram results made perfect sense, I kept

telling myself, " Maybe he's right. Maybe my hearing isn't as bad as the

audiogram says it is. "

I went through a roller coaster ride of emotions over the next few months

uintil I switched to another audi who could explain what was going on.

Thanks to her, I was able to put my hearing loss in perspective and turn my

fears into productiveness.

[Guest guest]

Hi all,

Cheating would not be a good thing for someone. If a person does well with

his HA il would not be interesting for her to undergo that surgery. The

chances of disappointment would be enormous for that personl. I can assure

that I had no intention of cheating on april 7 but ma hearing il so poor

that the rusult was certain. I will have my surgery on August 24, probably

for both ears.

Jacques from Montreal

Hi,

I do not know how much the hearing test reflect the reality. As you all

know, my motivation to get CI is not because I want to have CI, but rather,

out of my frustration in communication with people.
