A low-power cochlear implant system
Cochlear implants, or bionic ears, restore hearing to the profoundly deaf by bypassing missing inner-ear hair cells in the cochlea and electrically stimulating the auditory nerve. For miniaturized cochlear implants, including behind-the-ear (BTE) models, power consumption is the chief factor in …

Perception of prosody by cochlear implant recipients
Recipients of present-day cochlear implants (CIs) display remarkable success with speech recognition in quiet, but not with speech recognition in noise. Normal-hearing (NH) listeners, in contrast, perform relatively well with speech recognition in noise. Understanding which speech features support …

Electro-anatomical models of the cochlear implant
While cochlear implantation has become the standard care in treating patients with severe to profound sensorineural hearing loss, the variation in benefit (communicative ability) individual patients derive from implantation remains both large and, for the most part, unexplained. One explanation for …

Reflections on a Single Institution Cochlear Implant Experience
The general metadata -- e.g., title, author, abstract, subject headings, etc. -- is publicly available, but access to the submitted files is restricted to UT Southwestern campus access and/or authorized UT Southwestern users.

Acoustic models of consonant recognition in cochlear implant users
… conditions. By contrast, users of multichannel cochlear implants have difficulty with the accurate perception of consonants, even in good listening conditions. Cochlear implant users are known to show systematic deficits in recognition of consonant features, with perception of the place feature, …

Cognition and communication in children/adolescents with cochlear implant
A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive …

Using electrical stimulation responses to understand cochlear implant status
Cochlear implants (CIs) are neural prostheses that improve access to sounds for patients with severe to profound sensorineural hearing loss. CIs stimulate the auditory nerve with current pulses on a multi-electrode array that is placed inside the cochlea. Success of CIs varies based on a wide range …

Instrument identification through a simulated cochlear implant processing system
The signal processing used by cochlear implants is primarily designed to convey speech and environmental sounds, and can cause distortion of music. Although some studies of implanted listeners have demonstrated their limited ability to identify instruments, these results do not suggest whether the …

Towards artifact-free auditory evoked potentials in cochlear implant users
Cochlear Implantate (CIs) sind Prothesen, welche die Funktion der gesunden Cochlear imitieren. Dadurch können bei Personen mit einem sensorineuralen Hörverlust die Hörfunktionen wiederhergestellt werden. Eine noninvasive Methode, um die Rehabilitation des Hörsinnes nach der Implantation zu …

ERP correlates of semantic and syntactic processing in cochlear implant users.
… in this work given its compatibility with cochlear implantation. Cochlear implant (CI) is a neuroprosthesis that allows the acoustic signal to bypass the impaired inner hear system, by sending an electrical input directly to the acoustic nerve. Although it represents an important success …

Effect of cochlear shape and size on cochlear implant insertion forces
… the critical factors and parameters influencing cochlear implantation outcomes, with the ultimate aim to enhance surgical practices and patient outcomes. Chapter 2 offers a detailed overview of the anatomical and physical properties of the cochlea to aid the development of accurate models for …

Computational Models Explaining Cochlear Implant Principles: A Hypothesis, Applications and Physical Validations
… and clinical data to deepen our understanding of cochlear implants (CIs). For the past two or three decades, improvements in CI performance have been limited due to gaps in our understanding of how CI interacts with auditory nerves. Persistent questions, such as the unexplained polarity effect and …

Electrophysiological and behavioural measures of central auditory processing in adult cochlear implant users
… frequency discrimination in 12 experienced adult cochlear implant (CI) users and to compare the evoked potential results in the CI subjects to those of a group of age- and gender-matched control subjects with normal hearing. The CI subjects all used the Nucleus CI-22 implant with the SPEAK …

An overwhelming journey: Mothers of children cochlear implant users experiences with speech-language pathologists
… across the experiences of mothers of children cochlear implant users with speech-language pathologists. Parents describe learning that their child has a hearing loss as an overwhelming journey with much to learn and many decisions to make, especially in their child’s first year of life. Parents …
