Research summary
Hearing aids provide limited benefit to patients with severe to profound hearing loss. When people can no longer obtain satisfactory benefit from hearing aids, a Cochlear Implant (CI), which is an electronic device implanted into the hearing organ (cochlea), may be an option. Currently, only one CI is offered to adult patients. Many patients will have some residual hearing in their non-implanted ear and continuing to amplify this residual hearing with a hearing aid (bimodal stimulation) may be useful. CIs provide good speech understanding in quiet situations, however, they tend to provide poorer detection of other cues, such as accent, emotion, speaker gender or emphasis. Bimodal stimulation provides improved access to low pitched sounds which is not provided by the CI alone. The purpose of this study is to determine what benefit adults fitted with a CI and a hearing aid obtain when using both devices vs just the CI. Research into the benefits of bimodal stimulation is particularly relevant when considering the on going research into the potential benefit of bilateral CI for adult patients.
This study is part of Scientific Training Programme in Audiology (master's level) and will be sponsored by Guy's and St Thomas' NHS Foundation Trust Research and Development department. We plan to recruit 20 adult participants who are patients at the Hearing Implant Centre at Guy's and St Thomas' NHS Foundation Trust, over a period of 12 months. The data collection is planned in a single session, at the patient's routine 9-month follow up. This session is expected to last 1 hour. Participants will be asked to go through speech testing tasks in two conditions, CI alone and CI + HA, and complete a questionnaire (12 questions).REC name
