Studies on Pitch perception

[Guest guest]

Hi ,

I would love to have a copy of the studies you mentioned, I really do

not want to enter into any brand debates I am just thoroughly

interested in all things CI. I am currently in a study of Pitch

Perception so the timing of this information is great. The study I am

in at the moment is for a grad student doing her Thesis and there are

no brand comparisons that I know of, but it is interesting.

if you could eMail me the study you mentioned I would appreciate

it very much – HYPERLINK " mailto:gigabyte@... "

You are right and I apologize. I only recently switched to email and

started sending posts through that as I was going through the site

previously. After I saw the post, I noted there was no separation

between the quoted segments and my statements. So that should be the

last time that happens. I can imagine that was hellish for you.

The 2004 Spahr Dorman study had a melody recognition component. I

believe there are others that have done pitch perception testing,

however the gamut of these were done with previous implant releases

and have less value now. I am not aware of independent research

scoring pitch perception among implant users with channel

steering/channel shorting, however these tests would not likely be

done until after the commercial release of 120 Channels where both

implants more easily indepdendently tested. The currently published

results were done by AB researchers for the purpose of supporting

continued pursuit of the usage of current steering, which found that

users did improve both pitch perception and hearing in noise. That is

what justified AB's moving forward with it. Just as we didn't see

independent studies comparing CII and 3G users until 2 or so years

after release...the same will go for the Freedom and Harmony.

Cochlear's own studies are still of interest in the same manner as

AB's..but we have to wait for comparisons. My complaint is someone

referring to a study done but unable to produce the documentation that

outlines the results. Speaking of which, I'll be happy to provide the

studies done in support of current steering should anyone be

interested.
