• •NB: Patients included in another research project are not excluded from this one
• •NB: patients wearing a Lyric hearing prosthesis or any other permanent hearing prosthesis or cochlear implant can be included in the study but will not perform audiological examinations because the audiogram can't be easily performed without hearing prosthesis. Nevertheless, these patients could participate to the study with self-administered questionnaires and could be included as cases (i.e. patients with hearing deficiency) in analyses.
