Active clinical trials for "Hearing Loss, Sensorineural"

This thesis project proposes to investigate the "state of the art" of the programming of the cochlear implant. In the center of audiophonologie Brussels, the classic 'manual programming' has been in use over 20 years and also the new way 'Artificial Intelligence programming'. The investigators want to compare, objectify, and control this new mode of programming. The study is planned over 4 years, in order to test, randomized, 15 subjects with manual programming and 15 other subjects with Artificial Intelligence programming. To test the performance of Cochlear Implant patients, audiological, language auditory perception and questionnaire tests will be presented. This research aims to determine the contribution and results of Artificial Intelligence programming.

Main objective: Investigate how the FineHearing strategy of the MED-EL cochlear implant can extract prosody based solely on the frequency of the voice fundamental (F0) in speech Secondary objectives: Evaluate the time evolution of the results of prosodic tests Evaluate the time evolution of the results of differential frequency threshold test Evaluate the time evolution of vocal audiometric tests in silence and noise Evaluate the correlation between prosodic test results and frequency differential threshold results

Main objective: Show the superiority of Fine Structure (FS4) strategy compared to Continuous Interleaved Sampling (HDCIS) strategy on the qualitative preference for the listening of musical pieces. Secondary objectives Show the superiority of FS4 strategy compared to the HDCIS strategy on the perception of musical elements (contour test). Analyze the link between the results of musical perception tests and the subjective preference of musical listening. Show the non inferiority of FS4 strategy compared to the HDCIS strategy on the perception of speech elements. Analyze the link between the results of musical perception tests and the results of the perception of speech elements. Analyze the qualitative multidimensional perception with HDCIS and FS4

Speech intelligibility in noise will be evaluated in adults with moderate to moderate-severe sensorineural hearing loss using a Phonak Roger microphone and hearing aid with compatible Phonak Roger receiver. Target speech will be presented from multiple directions while competing diffuse background noise is presented simultaneously. Participants will repeat back words and percent correct is calculated.

Cochlear implants (CIs) are medical devices now widely used in persons with severe to profound hearing loss. After a six month to one-year period following implantation, adults typically reach optimal fitting parameters, which lead to a stabilized hearing performance with their CI. At this stage, they usually enter a routine clinical after-care program, which involves regular appointmentsattheir CI center. Such visits aim at identifying any complication, which can be medical (abnormal cutaneous healing evolution) and/or device related, as well as any declinein performance (possibly related to the former). In France, the HAS (French Health Authority) recommends CI users tobe seen around threetimes a year during the second and third years after implantation, and then annually. While the schedule of appointments remains dependent on centers' practices, there is some kind of consensus about the minimal content of a long-term follow-up session:medical consultation, CI external parts checking, free field aided tonal audiometry, fitting adjustments if necessary,speech understanding assessments. Our center (CRIC) is one of the biggest French CI implant centers approved by the HAS, providing after-care for no less than 750 CI users, most of whomhave entered their long-term follow-up period. For some, attending follow-up appointments may need several hours, require taking a half-day off work, and entail travel expenses. Some patients may also have associated disabilities making it difficultto reach the center.Moreover, although the cohort of patients has increased over the years, the number of trained professionals and the clinical care infrastructures have not evolved proportionally. As a consequence, there is a need to reduce the number of routine visits, to allow more scope for complex cases andto efficiently identify issues. Remote consultation seems to address all the points listed above. However, it appears that little has been doneto develop remote after-care for cochlear implant recipients. Published studies mainly focus on the fitting aspects. The development of telemedicine has become one of the key priorities of the French government over the past few years, and it is now feasible thanks to the development of high speed connections (ADSL, mobile internet, high definition transmissions). Promoting telemedicine has several goals, the main one being to extend health care services to underserved patients in remote locations; it also allows some medical units to be freed upand to reserve infrastructures and professionals for patients requesting critical care. Of course, telemedicine is also meant to save costs. The objectif of this protocole is to evaluate the feasibility of telemedicine applied to adult cochlear implant users' follow-up by comparing the data of the medical consultation and speech therapy assessment, carried out in the CRIC service and videoconferencing when the patient is home, using his computer equipment to communicate with the CRIC.

Bilateral severe to profound hearing loss is a socially disabling handicap. Cochlear implants can be used to improve hearing in cases where conventional hearing aids are not effective. There are few studies about the long latency Auditory Evoked Potential (P300), in individuals with hearing loss and Cochlear Implant (CI) users. The aim of this project is to study the behavior of P300 in users of unilateral CI.

The objective of this study is to make a comparison between two surgical techniques used when implanting a Ponto bone anchored hearing system.

Purpose: The purpose of this study is 1) to evaluate the safety and efficacy of currently available multichannel cochlear implant systems for newly implanted adults with an indication based on open-set sentence recognition that expand criteria currently used by Center for Medicare & Medicaid Services (CMS), and 2) to assess the correlation between measures of speech recognition in candidates for cochlear implants and their utility in predicting audiologic and quality of life outcomes after implantation. Participants: Adults (≥ 65 years of age) and CMS-eligible as a primary source of medical insurance coverage. Procedures (methods): Evaluate objective and subjective outcomes of cochlear implantation in a patient population that does not meet current CMS candidacy criteria.

The purpose of this study is to find out whether the High Frequency Digit Triplet test can be used to screen patients with cystic fibrosis for hearing loss in conditions of health and pulmonary exacerbation. It is also designed to find out the youngest age at which a child can perform the test, the prevalence of hearing loss in a CF population and the prevalence of genetic mutations known to be associated with hearing loss in the same population.

Within the course of this study, a signal processing feature has been developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with Sonova AG, in order to enhance the listening experience with remote microphone systems. In particular, the developed feature is supposed to improve the so-called audio-visual fusion, i.e. the fact to perceive the sound as coming from the physical location of the source. One of the main goals of the present study is to evaluate the extent to which this feature reaches that objective.
