Study Stopped
Demant's transfer of its cochlear implant activity to Cochlear. Slow recruitment and misalignment with Cochlear's interests are also determining factors.

Outcome Measures
Primary Outcomes (1)
Measurement of the pupil dilation response to a range of auditory stimuli (acoustic and electric).
Pupil dilation response for each intensity and frequency \[Mean pupil dilatation in milimeters\]
At Visit 2 (Month 1)
Secondary Outcomes (1)
Evaluation of the loudness perception of the subjects regarding the different auditory stimuli (acoustic and electric) to correlate the results to the pupil dilation response.
At Visit 2 (Month 1) and Visit 3 (Month 2)* [* if done]
Study Arms (2)
Control group (normal hearing in regards of age)
OTHERNormal hearing participants according to pure tone hearing levels defined for age and tested frequency (audiometry ISO 7029 and Wang \& Puel, 2020 recommendations for hearing loss at the tested frequencies). Total of 32 subjects in this arm.
CI group (cochlear implanted subjects)
EXPERIMENTALCochlear implanted subjects with bilateral, severe-to-profound sensorineural hearing loss, with at least one Oticon Medical cochlear implant system . Up to 40 subjects in this arm: * 20 subjects will perform experiment 1 \& 2 * 20 subjects will perform experiment 3 * The subjects of the experiment 3 ore either those taken part to experiment 1 and 2, or subjects who only take port to the experiment 3
Interventions
Pupillometry measurements are carried out by a dedicated device (eye tracker), which includes cameras allowing the measurement of pupillary dilation. The subject stands in front of a screen and fixes a point in the center of the screen, the cameras placed on the screen allowing a measurement of the pupillary dilation in a non-invasive way. These eye-tracking measurements are performed simultaneously with an auditory task and allow to study the pupil's response to different stimuli.
Eligibility Criteria
You may qualify if:
- Both groups:
- Adult (≥ 18 years old)
- Fluent in French language
- Affiliation to social security
- Information and signature of a written consent prior to any study-specific procedure
- Control group (normal hearing in regards of age):
- Normal hearing participants according to pure tone hearing levels defined for age and tested frequency (audiometry ISO 7029 and Wand \& Puel, 2020 recommendations for hearing loss at the tested frequencies)
- CI group (cochlear implant subjects):
- Bilateral, severe-to-profound sensorineural hearing loss, with at least one cochlear implant system
- Using Oticon Medical Neuro Cochlear Implant System (NCIS) or Digisonic Cochlear Implant system (DCIS), unilateral or bilateral
- Duration of cochlear implant experience ≥ 6 months (period from cochlear implant activation to study enrolment)
- Pure Tone Audiometry must be strictly below 50 dBA, CI aided.
You may not qualify if:
- Both groups, according to the best practices for pupillometry (Winn et al., 2018):
- Eye diseases: nystagmus, amblyopia, and macular degeneration
- Severe head injury or any history of significant neurological problems: These issues can affect gaze stability, congruence of eye movements, and pupil dilation
- Concomitant medication that can impact the parasympathetic autonomic nervous system
- Person under State Medical Assistance (AME for "Aide medical d'état" in French)
- Use of one of the following treatments: Trihexyphenidyl, Biperiden or Tropatepine (anticholinergics, commonly used in the treatment of Parkinson's disease)
- Person under legal protection (guardianship, curators, other, etc.) or under family authorization
- Unwillingness or inability to comply with all investigational requirements
- Additional cognitive, medical, or social handicaps that would prevent completion of all study requirements
