Filter by:The primary objective of this study is to determine the (long term) effect of intervention with a CI in adult participants with progressive postlingual moderate/severe-to-profound sensorineural hearing loss on societal related outcomes (participation; communication profile; autonomy; cognition; listening effort; work; productivity loss; income; medical consumption; third party quality of life; quality of life, and capability). The secondary objective is to determine the effect of CI waiting time between referral and CI surgery on the same societal related outcomes, in the adults with postlingual moderate/severe-to-profound sensorineural hearing loss.
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. This study aims to investigate the current freqeuncy response curve in the manufacturer's products to variations of these curves to determine if hearing aid users prefer the variations over the manufacturer's standard curve.
This trial will evaluate a multilevel intervention (STAR model) that combines mobile health (mHealth) hearing screening tools with telemedicine technology for specialty care access in rural Kentucky schools. An initial version of the model was used in rural Alaska where telemedicine-based specialty referral improved both proportion of children receiving follow-up and time to follow-up. The refined STAR model will utilize an enhanced mHealth screening protocol that includes tympanometry for the detection of middle ear disease. The STAR model will also include a specialty telemedicine referral process in schools for children who refer school screening.
This study will improve the understanding of the cerebral mechanisms that underlie the control of auditory selective attention and evaluate the potential of neuromodulation to enhance neural attention control as a possible way to overcome hearing impairment. First, electroencephalography (EEG) will be applied to identify neural marker of auditory attention in individuals with hearing loss (HL), tinnitus (TI) and normal hearing (NH). Afterwards, the importance of the identified markers for attention control will be tested using non-invasive transcranial alternating current stimulation (tACS) and neurofeedback (NF).
This study is designed to advance the promising yet underutilized research on retrieval practice by evaluating the effectiveness and efficiency of two key retrieval practice features (feedback and spacing). The study uses four single case adapted alternating treatments studies, each with four 5- to 8-year-old children who are deaf and hard of hearing to evaluate the effects of feedback and spacing on the efficiency of word learning and retention.
In an era of advanced industry and commerce, working in a noisy environment is one of the most important risk factors for hearing damage, especially among young and middle-aged people. Although acupuncture has been widely used to treat otology-related diseases, such as tinnitus, dizziness, and sudden deafness, there are few studies on the effect of noise-induced hearing loss.
Severe-to-profound hearing loss can have a major impact on patients´ lives leading to social isolation and decreased quality of life. Most commonly the hearing loss is caused by damage to the inner ear or cochlear nerve. Since the vestibular system which is central for our balance is located in the inner ear it can be suspected that patients with severe-to-profound hearing loss also might have an impaired vestibular function. This impairment may lead to a feeling of dizziness or vertigo. This study aims to investigate if patients with severe-to-profound hearing loss also have impaired vestibular function. The vestibular function will be measured with caloric irrigation, video head impulse test and vestibular evoked myogenic potential.
This study aims to evaluate a cochlear implant headpiece.
Patients with hearing loss who use cochlear implants (CIs) show significant deficits and strong unexplained intersubject variability in their perception and production of spoken emotions in speech. This project will investigate the hypothesis that "cue-weighting", or how patients utilize the different acoustic cues to emotion, accounts for significant variance in emotional communication with CIs. The results will focus on children with CIs, but parallel measures in postlingually deaf adults with CIs will be made, ensuring that results of these studies benefit social communication by CI patients across the lifespan by informing the development of technological innovations and improved clinical protocols.
This is a feasibility, prospective with sequential enrolment, multicenter, clinical investigation in adults and paediatrics with a CE approved Nucleus cochlear implant. Subjects older than 5 years will be included. Subjects will be screened and up to 120 eligible subjects will be recruited in the clinical investigation. Subjects will attend scheduled study visits over a period up to 5 years in different sub-studies as described in the sub-study documentation. A clinical setting can consist of therapeutic elements and evaluations. Subjects will be assessed with the commercially available Nucleus sound processor or via the xPC, NIC, etc. if required. Acute testing will be done where possible. Take home use will be applied when learning effects may play a significant role and to evaluate the acceptance of the new or improved sound coding algorithm or signal processing, in as many listening environments as possible. The subject might also be asked to complete questionnaires, to perform at-home tests etc. during this take home use and/or at the clinical visits. The time for a clinical visit will be limited to a maximum of 4 hours. The time in between clinical visits will vary with typical spacing of between 0 (acute) to 4 weeks. The goals of this umbrella investigation are to measure hearing outcomes to assess performance and/or to achieve higher convenience for implant users and hearing care professionals. The outcomes of the study will guide Cochlear to select features for inclusion in future Nucleus cochlear implant systems and/or future models of care.
