These implants utilize the functionality of the human middle ear and require adequate speech conduction through the middle ear chain. Consequently, the clinical test of this degree of speech transfer can contribute to the pre-operative indication for middle ear implants.\n\nWideband Tympanometry (WT) is a non-invasive diagnostic tool for the clinical assessment of the condition of the middle ear. Unlike classical tympanometry, WT tests the impedance of the middle ear system as a function of both pressure and frequencies. Consequently, a WT measurement contains many times more information about the functionality of the middle ear than classical tympanometry and is ideally suited as a diagnostic tool for the clinical assessment of speech transfer through the middle ear. The WT measurements will be correlated with the Speech Intelligibility Index (SII) collected in normally hearing individuals and patients with isolated conductive hearing loss. This index is a measure of speech transfer through the middle ear. Consequently, a correlation of the WT measurements with the SII addresses the need for a non-behavioral clinical test of speech transfer through the middle ear.\n\nAdditionally, WT measurements will be performed longitudinally in cochlear implant candidates, one of the populations that can benefit from the developed clinical test. These longitudinal WT measurements, which will be performed both pre- and post-operatively, allow for the evaluation of the impact of middle ear surgery on the predicted SII.",[28],"RECRUITING","2026-04-24",{"date":62,"type":38},"2026-04-29",{"date":64,"type":38},"2025-07-04",{"date":66,"type":21},"2027-11",{"name":68,"class":69},"Universitaire Ziekenhuizen KU Leuven","OTHER",{"id":71,"slug":72,"hasResults":11,"nctId":73,"briefTitle":74,"officialTitle":75,"acronym":4,"eligibilityCriteria":76,"healthyVolunteers":15,"sex":16,"minAge":77,"maxAge":78,"enrollmentInfo":79,"targetDuration":4,"studyType":22,"phases":81,"briefSummary":82,"conditions":83,"keywords":84,"overallStatus":59,"whyStopped":4,"lastUpdateSubmitDate":87,"lastUpdatePostDateStruct":88,"startDateStruct":90,"completionDateStruct":92,"leadSponsor":93,"locationsCount":46},"100610024","evaluation-of-flexible-conductive-hearing-aids-100610024","NCT07222202","Evaluation of Flexible Conductive Hearing Aids","A Noninvasive, Flexible Conductive Hearing Aid With Micro-epidermal Actuators on Pediatric and Adult Patients","Inclusion Criteria:\n\n* Male and female infants, children, adolescents, and adult patients who are diagnosed with unilateral or bilateral mixed or conductive hearing loss\n* Male and female patients seen at Atrium Health-Audiology for a clinical, standard of care office visit who have a diagnosis of conductive or mixed hearing loss and may currently wear hearing aids\n* Male and female infants, children, adolescents, and adults who are candidates for conductive hearing aids (Osseo-integrated or wearable aids) or for canalplasty or ossicular chain reconstruction surgery\n* Healthy subjects will include male and female infants, children, adolescents, and adults who do not have conductive or mixed hearing loss\n* Pregnant women -are eligible for this study.
