Temporal coding and music perception in bimodal listeners.

Objective: Limited low frequency (LF) pitch and temporal fine structure (TFS) sensitivity have been thought to contribute significantly to poor music perception in cochlear implant (CI) listeners. Thus, this study aimed to evaluate music perception in relation to LF pitch perception and temporal coding, specifically in people with bimodal stimulation as a promising approach to improve spectro-temporal sensitivity in CI listeners.

Methods: Eleven postlingually deafened bimodal listeners participated in the study (mean age=55.

The role of speech rate for Italian-speaking cochlear implant users: insights for everyday speech perception.

This study investigated the effect of speech rate for Italian-speaking cochlear implant (CI) users with the aim of gaining insight into everyday listening situations where speaker's rate may vary considerably together with speech level in fluctuating background noise. The test material was prepared by processing the Italian STARR test with temporal compression of sentence material. Twelve adult CI users were divided into two subgroups based on their STARR performance: good and poor performers.

Temporal Fine Structure Processing, Pitch, and Speech Perception in Adult Cochlear Implant Recipients.

Objectives: The aim of the study was to investigate the link between temporal fine structure (TFS) processing, pitch, and speech perception performance in adult cochlear implant (CI) recipients, including bimodal listeners who may benefit better low-frequency (LF) temporal coding in the contralateral ear.

Design: The study participants were 43 adult CI recipients (23 unilateral, 6 bilateral, and 14 bimodal listeners). Two new LF pitch perception tests-harmonic intonation (HI) and disharmonic intonation (DI)-were used to evaluate TFS sensitivity.

Adaptation of the STARR test for adult Italian population: A speech test for a realistic estimate in real-life listening conditions.

Objectives: To introduce the Italian adaptation of the STARR test based on a roving-level adaptive method to mimic challenging real-life listening conditions for use in people with auditory prostheses.

Design: Normative data were collected and interlist-variability, as well as learning effects, were investigated using a within-subject design with repeated measures.

Study Sample: A group of 32 normal-hearing (NH) adults participated in the study.

Long term results in late implanted adolescent and adult CI recipients.

The aim of the present study is to assess long-term outcomes of CI in prelingual deafened adolescents and adults, describing, where present, differences in performance, self perceived benefit and highlighting specific characteristics. Twenty-three patients were enrolled: 10 adolescents, 13 young adults. Each patient underwent speech perception/language development, psychological evaluation and structured interviews on self perception concerning CI.

Implementation of perceptual channels in children implanted with a HiRes 90K device.

Conclusions: The increased spectral resolution that characterizes the HiRes 120 device contributes to improvement of performance. Discrimination and identification in noise are consistent with reports of improved perception under everyday listening situations.

Objectives: This work focuses on speech perception findings after implementation of current steering in HiResolution strategy of children implanted with Clarion HiRes 90K.

Schooling and educational performance in children and adolescents wearing cochlear implants.

Objective: The aim of the study was to assess the impact of cochlear implant use on schooling.

Design: Retrospective study which examined the educational characteristics, gap between chronological age and class attended, learning skills and quality of social interaction with peers and adults in 50 children with cochlear implants.

Methods: Structured interviews with parents, questionnaires for teachers, school report cards and psychometric tests.
