Filter by:This observational study aims to validate the use of a tablet based audiometer to provide an accurate, efficient, and cost-effective means for diagnosis of hearing conditions in controlled and uncontrolled environments in adult and elderly populations.
This study investigate weather one type of cochlear implant (CI) surgery (insertion of the electrode via paracentesis of the round window (RWA)) leads to less vertigo than another type of CI surgery (cochleostomy). The participants will be randomized into 2 groups: RWA or cochleostomy. They will be examined with a video head impulse test (vHIT) before and after CI surgery to clarify their vestibular function.
Next Generation Sequencing (NGS) strategy is a powerful tool to identify genes implicated in very rare diseases for which the previous genetic explorations remain negative to date. The aim of this project is based on groups of patients with original clinical phenotypes including neurosensory impairment without genetic cause identified to date. The investigators will study these families using whole exome sequencing to potentially identify new genes and new underlying biological pathways involved in neurosensory diseases.
The purpose of this study is to evaluate the benefit of bimodal hearing and bilateral cochlear implant hearing in comparison to unilateral cochlear implant hearing in the perception of speech intonation.
This study is a feasibility study of the Nucleus 24 ABI in children without NF2. It will be conducted as a repeated-measures, single subject experiment in order to accommodate the known variability in cochlear implant clinical results. Data obtained in the course of this study will be compared with the existing published outcome data from children with normal hearing and with cochlear implants (CIs). These comparisons may provide additional useful information about the progress of ABI subjects' performance over time. Also, this may allow the results of the current study to be utilized to design future pivotal studies of the device in the pediatric population.
The purpose of this study is to find out whether the High Frequency Digit Triplet test can be used to screen patients with cystic fibrosis for hearing loss in conditions of health and pulmonary exacerbation. It is also designed to find out the youngest age at which a child can perform the test, the prevalence of hearing loss in a CF population and the prevalence of genetic mutations known to be associated with hearing loss in the same population.
The specific aim of this research is to evaluate the performance, effectiveness, and long-term training benefits of a formal hearing protection fit testing program. This study may provide preliminary evidence on the benefits of direct education/training combined with a formal hearing protection device (HPD) fit testing on HPD fittings on United States Air Force (USAF) employees. Currently, Public Health provides informal, subjective training to employees; this practice may be altered by the results of this study.
Treatment with cochlear implantation is now offered to proximately 95 % of children with deafness in Norway. More than 500 children have been operated at Oslo University Hospital. The study is a cross-sectional study aimed to investigate speech perception, language skills, quality of life in all childhood cochlear implant (CI) recipients in Norway from 1988-2012. Factors such as child characteristics, characteristics with the family, the cochlear implant, the rehabilitation situation, choice of communication mode, school and work situation are surveyed to see if these factors can be associated with variations in outcome. The study will include pre and post lingual deaf children and children with multiple disabilities. Participants are recruited and examined in conjunction with their annual CI control at the hospital. It will be conducted a series of tests determining listening, speech and language development, non-verbal intelligence. Questionnaires are used to collect background information and quality of life experience. The questionnaires include self-report forms for different age groups, and a parent report form. The patient will be tested for the most common genetic causes of deafness. Additional data will be collected from patient records and from local health register at Oslo University Hospital.
The objective of this multi-site observational study is to further assess the long-term patient use of the Sonitus SoundBite Hearing System. Information can be gained by assessing benefit for the subjects that were enrolled in the SoundBite Hearing System Long Term Multi Site Study (Protocol CLN006) for an additional 12 months.
Differences in speech-understanding and the quality of the subjective perception among cochlear implant patients (Digisonic SP) depends on numerous factors. The electrical field distribution (interaction between electrodes) could also explain the disparity of the performances? The objective of our study was to quantify the influence of the electrical field interactions between the channels of stimulation according to the vocal performances of the implanted subjects, for various subjective levels of electric stimulation.
