Research summary
This is a feasibility study designed to be conducted in preparation of a full scale future study. This study will be conducted as part of the award of DClinSci from the University of Manchester. The study will take place at University Hospitals Birmingham Cochlear Implant department and will involve prospective evaluation of patients with cochlear implants.
The Cochlea is the sensory organ for hearing. A Cochlear Implant (CI) is a surgically implanted device designed to restore hearing for people with moderate-to-profound hearing loss. CIs function by delivering an electrical signal within the cochlea to elicit a neural response and subsequent perception of sound. CI manufacturers in the UK typically use an electrode comprising 16-24 stimulating electrodes designed with the principle of stimulating multiple frequencies and replicating normal cochlear function.Previous studies have addressed the impact reducing the number of stimulating electrodes has on a patients ability to perceive speech. This study aims to assess the feasibility of delivering a full crossover study designed to gain further insight into the impact reducing the number of stimulating electrodes has on the amount of effort a patient exerts to support listening when using modern CIs.REC name
