Assessment of telephone speech perception in individuals who received cochlear implant in the period 1993-2003.

Objective: To evaluate telephone speech perception in individuals who received cochlear implant in the period 1993-2003.

Methods: Twenty seven CI users were divided into pre and post-lingual groups, being the speech perception assessed in two stages: first by a list of sentences imposed on speakerphone with the same mapping used to evaluate the phone and, in a second stage, using the landline, landline phone adapter with CI and cell phone.

Results: In the group of pre-lingual hearing loss, 75% of subjects were able to maintain a dialogue with the interlocutor and 19% did so with difficulty.

Temporal organization skills in cochlear implants recipients.

Unlabelled: Processing acoustic clues from the sounds of speech depends on the proper perception of the frequency and duration of stimuli as a sequence of events.

Aim: To assess the capacity for temporal organization in users of multichannel CI.

Method: 14 normal hearing individuals formed the control group, matching in age and gender other 14 users of multichannel CI, who made up the study group, and they were assessed and compared as to the Frequency Patterns Test (FPT) and Duration Patterns Test (DPT).

[Oral language of children with five years of experience using [corrected] cochlear implant].

Background: Cochlear implant (CI) in children.

Aim: 1) to delineate a profile of receptive and expressive verbal language of children who have been using cochlear implant for five years and five years and eleven months; 2) to verify the influence of time of auditory sensorial privation in the receptive and expressive verbal language of these children.

Method: 19 children users of CI with auditory deficiency acquired before language development, who have been using CI for 5y - 5y11m and who have an average time of sensorial privation of 3y (standard deviation of 1 year).

Evaluation of speech perception in noise in cochlear implanted adults.

Aim: To evaluate the effects of different signal-to-noise ratios on speech recognition obtained by the use of cochlear implant (CI); to compare the speech recognition in noise with different types of multichannel cochlear implants (CIs) and to evaluate the degree of difficulty for speech understanding in noise in daily life situations.

Study Design: Cohort transversal.

Material And Method: Forty adults with post-lingual hearing loss implanted with Nucleus 22, Nucleus 24, Combi 40, Combi 40+ and Clarion.

[Speech perception in cochlear implant users: two programming situations].

Background: In order to shorten the programming process of cochlear implanted (CI) children it is possible to establish the T level (threshold level) as being 10% of the C level (most comfortable level).

Aim: To compare the results of speech perception tests using the map of the real thresholds levels and the map corresponding to 10% of the C level. MRTHODS: A list of monosyllables and sentences were used with 30 CI individuals in two programming situations.
