Filter by:The goal of this interventional study is to describe how people with cochlear implants perceive the perceive speech in noise and their sound environment on adults who are native French speakers with typical hearing or with cochlear implant(s). The measures and strategies developed in this project could benefit all current and future cochlear implant wearers by improving their perception of the sound environment and their quality of life on a daily basis. Researchers will compare normal hearing participant and participants with cochlear implant to describe the speech in noise and their perception of the sound environment. Participants will perform audiological tests to assess their perception of the sound environment, with and without speech enhancement.
Cochlear implants (CIs) are devices that partially restore hearing for people with severe to profound hearing loss. This research focuses on CI users who use bilaterally implanted devices (two CIs, one on each side) and also "single-sided deafness" (SSD) CI users who use one CI together with good acoustic hearing in their opposite ear. The goal is to measure and understand the impact of large input asymmetries across the two ears. These asymmetries are common in BI-CI listeners and always present in SSD-CI users. Although most CI listeners benefit from a second source of auditory input, this project measures how these asymmetries limit speech understanding and spatial hearing. The long-term goal is countering or compensating for input asymmetries. Electrophysiological measures are used to describe the health of the auditory system. Behavioral measures are used to assess if training improves performance. CT imaging is utilized to describe the placement of the CIs.
This is a retrospective study designed to collect speech perception results for HiRes Ultra CI and HiRes Ultra 3D CI users as measured in the clinical routine and to confirm the performance of these devices.
This is a retrospective study designed to collect long-term speech perception results for cochlear implants recipients using electro-acoustic-stimulation as measured in the clinical routine and to confirm the performance of sound processors associated with acoustic earhooks.
Cochlear implantation (CI) allows rehabilitation for patients with severe to profound hearing impairment. Although the use of a robotic assistant provides technical assistance to the surgeon, the assessment of the impact of its use on auditory outcomes remains uncertain, due to inter-individual variability of preoperative audiometric thresholds and the various possible intrascalar positions of the electrode array. WThe investigators aim to compare the hearing results of patients who underwent bilateral cochlear implantation, one side was performed with manual insertion and the other side with robot-assisted insertion. The electrode array intrascalar positioning and the surgery duration were also studied. This retrospective intra-individual study involved 10 patients who underwent bilateral cochlear implantation. The unique composition of this cohort enabled the investigators to utilize each patient as their own control.
An observational study to determine and assess perception of prosodic information in adults who use bimodal stimulation (cochlear implant plus hearing aid) when using both devices vs. cochlear implant alone.
This study investigates a newly developed test, The CochSyn test that can quantify cochlear synaptopathy (CS) (a new type of sensorineural hearing loss (SNHL)) earlier than the current golden standard pure-tone audiogram.This newly developed test is based on auditory evoked brain potentials. A hardware prototype (the Cochsyn test prototype) was developed to use the Cochsyn test in clinical practice. Additionally a CS-based sound-processing algorithm (CoNNear) that is designed to improve speech intelligibility in subjects that are identified to have CS, will be investigated in this study.
The Cochlear Implant - Quality of Life (CIQoL) PROM is a quality-of-life assessment questionnaire for adults with cochlear implants. The CIQoL responds to an important need for a questionnaire that captures the benefits of cochlear implantation as perceived by patients and that can be used in clinical practice.
This trial is a monocentric, prospective and controlled study of the pupil response to detect hearing threshold and comfortable loudness of normal-hearing (NH) and CI-subjects.
Older adults who use cochlear implants to address hearing loss show wide variation in benefit. This research investigates the role of normal aging, the health of peripheral and central auditory pathways, and positioning of the cochlear implant electrode array in contributing to this variability. A range of input types from simple auditory signals to spoken sentences is used to examine these questions.
