CHANGE Feasibility Study

The purpose of the feasibility study is to examine audiological outcomes (audiometry and speech perception) and safety (adverse events and adverse device effects) with the Nucleus CI532 co...

Speech Perception for Children With Cochlear Implants

The purpose of this study is to determine whether speech recognition in noise can be improved by the addition of a special listening program to the sound processor. Thus we propose to asse...

Relationship Between Auto NRT and Behavioural T & C Levels With the Nucleus Freedom Cochlear Implant

Cochlear implants require programming on an individual basis to provide appropriate levels of electrical stimulation. This program, or "map", is placed in the speech processor of the cochl...

Iowa/Nucleus 10/10 mm and Nucleus Freedom Feasibility Study

The purpose of this study is to evaluate whether the Iowa/Nucleus 10/10 mm in one ear, in conjunction with a Nucleus Freedom implant in the other ear can provide useful binaural hearing in...

Clinical Evaluation of a Cochlear Implant System

The primary objective of this study is to assess the usability of a Cochlear implant system.

Bimodal benefit for cochlear implant listeners with different grades of hearing loss in the opposite ear.

To determine speech perception in quiet and noise of adult cochlear implant listeners retaining a hearing aid contralaterally. Second, to investigate the influence of contralateral hearing thresholds ...

Comparison of the Spectral-Temporally Modulated Ripple Test With the Arizona Biomedical Institute Sentence Test in Cochlear Implant Users.

Although speech perception is the gold standard for measuring cochlear implant (CI) users' performance, speech perception tests often require extensive adaptation to obtain accurate results, particula...

Improved Speech Perception in Cochlear Implant Users With Interleaved High-Rate Pulse Trains.

Electrical stimulation with a cochlear implant (CI) elicits abnormally high neural synchrony, which poses significant challenges for speech perception. Previous investigations showed that constant-amp...

Fixed and adaptive beamforming improves speech perception in noise in cochlear implant recipients equipped with the MED-EL SONNET audio processor.

To determine the impact of the fixed and adaptive beamforming technology of the new MED-EL SONNET cochlear implant audio processor on speech perception in noise.

An Evaluation of Output Signal to Noise Ratio as a Predictor of Cochlear Implant Speech Intelligibility.

Cochlear implant (CI) sound processing strategies are usually evaluated in clinical studies involving experienced implant recipients. Metrics which estimate the capacity to perceive speech for a given...

Medical and Biotech [MESH] Definitions

The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.

The brain stem nucleus that receives the central input from the cochlear nerve. The cochlear nucleus is located lateral and dorsolateral to the inferior cerebellar peduncles and is functionally divided into dorsal and ventral parts. It is tonotopically organized, performs the first stage of central auditory processing, and projects (directly or indirectly) to higher auditory areas including the superior olivary nuclei, the medial geniculi, the inferior colliculi, and the auditory cortex.

Acquired or developmental cognitive disorders of AUDITORY PERCEPTION characterized by a reduced ability to perceive information contained in auditory stimuli despite intact auditory pathways. Affected individuals have difficulty with speech perception, sound localization, and comprehending the meaning of inflections of speech.

Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.

The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the SPIRAL GANGLION and project to the cochlear nuclei (COCHLEAR NUCLEUS). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the VESTIBULAR NUCLEI.
