Cochlear implants are routine treatment for people with severe hearing loss. This study tests the RONDO 3, MED-EL's newest single-unit audio processor which comes with new features (Beamformer, Wind-Noise reduction, Ambient noise reduction, Transient noise reduction, Adaptive intelligence).
Individuals with cochlear implants will complete tasks which measure auditory resolution, working memory, stream segregation, and speech recognition in the presence of competing speech using their everyday clinical device settings. The relationship between these tasks will be examined to identify the factors which predict successful speech recognition in the presence of competing speech.
The purpose of this study is to see if remote programming visits for cochlear implants are possible.
This clinical investigation aims to collect data on the use of the Mi2000 system, a totally implantable cochlear implant system, for the first time in human subjects.
The goal of this study is to take into account channel interaction in the cochlear implant (CI) fitting process. Designing a fast and accurate method of measurement would help to customize the fitting procedures to patients' specificities in order to maximize speech understanding in every day conditions especially in noise.
MED-EL Cochlear Implants (CI) provide auditory sensations via electrical stimulation of the auditory pathways for severely to profoundly hearing-impaired individuals who obtain little or no benefit from acoustic amplification in the best aided condition. Front-end processing of acoustic signals picked up by the audio processor is routinely applied to provide optimal hearing performance under varying listening conditions. Automatic Sound Management (ASM) was introduced by MED-EL with the TEMPO+ audio processor. With the new SONNET 2 audio processor, ASM 3.0 was implemented and the features noise reduction, transient reduction and an automatic scene classifier were added. This study will investigate the impact of ASM 3.0 as implemented in the SONNET 2 on CI users' speech performance and their subjective quality of hearing.
Investigation of a new ECoChG system (Electrocochleography) during the surgical insertion of cochlear implants, for patients with Advanced Bionics devices. The sound recordings created may be useful in aiding the surgeon to better implant the patient by letting him or her know if they are damaging the ear during implantation in real time Patients will be followed up for 1 year post surgery within our trial, and have a further 3 ECochGs performed in the clinic setting, (6 weeks, 6 months, 1 year) through their implants.
This project will complete a long-term follow up for children that have received cochlear implants (CI) early in life and had their CI's programmed based on objective measurements. At Sahlgrenska University Hospital in Gothenburg, generally, all younger children (0-3 years), the last ten years, had their CI's programmed based on objective measurements. The programming of the CI carried out during the first year after the surgical insertion is done on the foundation of the objective measurements and is generally what the child will live with thereafter. This method also seem to be close to other clinics in Sweden and the rest of the world, however, there are no specific guidelines regarding the how the programming of the CI is to be carried out on small children. To this date there are no studies, to our knowledge, that have confirmed the validity of using these objective measurements and if it is the best for the child. We therefore aim to do a long term follow up on children that have received CI and programmed this way, and study if there would be beneficial to redo the programming when the child is old enough to actively participate. The aim with this project is evaluate how suitable it is to mainly use objective measurements when programming the cochlear implant and, in addition to this, examine if the children's hearing can be improved if the programming is based on the behavioral measurements of sound when the children are old enough to participate in such. It will examine what happens with the end result if the programming foundation differentiates from one another; if there are any measurable differences in hearing skills. The result from this project expects to generate knowledge that is highly important for those working with small children receiving CI's, and by extension it will benefit the children that rely on this device in there every day life.
The objective is to investigate the new Naida CROS device in adult recipients including chronic phases and to generate some preliminary pre-launch data. The formal study objectives are to compare the speech intelligibility in quiet and noise when using the CROS device with the Naida CI Q70 processor versus the Naida CI processor alone in quiet and noise conditions. Subjects will be tested with and without CROS at the baseline visit and then at follow-up visits taking place one month and three months after baseline. Subjects will use the new device at home between the first two visits appointments and then will only use the Naida CI processor for two additional weeks to better evaluate the handicap of not having access to contralateral signal input. There will be four visits to the centre in total. Subjective feedback will be collected through questionnaire like the APHAB and Speech, Spatial and Qualities of Hearing Scale (SSQ). A customised questionnaire focusing usability and benefit of the CROS will also be administered. Additional interest of the study will be to evaluate any acclimatisation effect with the CROS device both objectively and subjectively.
