Active clinical trials for "Deafness"

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy (TFS4) to a default fitting strategy (FS4) for the speech recognition in noise. Secondary objectives: Comparison of TFS4 to FS4 for speech recognition in quiet. Comparison of TFS4 to FS4 for the auditory skills experienced by the subject.

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.

In this study, the investigators hypothesize that studying monogenic variants with strong effect associated with severe insulin deficiency of Wolfram syndrome will provide important insights into the more complex type 1 and type 2 diabetes mellitus. Aim 1. Establish and maintain a registry of patients with Wolfram syndrome. An Internet based registry will be employed to enroll participants with the clinical diagnosis of Wolfram syndrome (insulin dependent DM and bilateral OA). Clinical information regarding age of diagnosis and progression of the disease will be collated and analyzed to better define its natural history, along with potential metabolic phenotypes such as glucose intolerance of heterozygous parents and unaffected sibs. If not already completed, blood for WFS1 sequence analysis will be obtained on the participants (parents and sibs also for control purposes) and sent to a CLIA certified lab to define the mutation. This information will benefit patient families and referring physicians by providing a genetic diagnosis and where indicated. The Wolfram Syndrome Registry will foster international collaborations to more efficiently and systematically collect Wolfram syndrome patients and their clinical and experimental data.

The primary purpose of the research is to study how synthesized speech and non-speech percepts (sounds) are recognized in subjects with cochlear implants (CI) who are not getting functional speech recognition using existing speech to CI algorithms. By identifying a partial set of phonemes (units of speech) from this CI feedback, a new language could be developed.

The principal aim of this study is to evaluate the cortical developement of perceptual skills and executive functions over time, in children with cochlear implants aged 10-24 months and 3-7 years compared with normally hearing subjects (NHS). To do this, the investigator will use functional Near InfraRed Spectroscopy (fNIRS) during 4 tasks that engage the childs perceptual and cognitive skills over a period of 18 months. The performance scores obtained by each participants as well as the cortical activity will be analysed and decrypted.

This descriptive and observational research project aims to characterize MMN as a neuronal marker of localization deficit in single-sided deafened subjects and subjects with bilateral profound deafness treated by a cochlear implant (CI). It includes several electro-physiological and psychoacoustic assessments performed on subjects with single-sided deafness and cochlear implanted subjects, with normal-hearing subjects as control: Evaluation of the characteristics of the MMN involved in sound localization by EEG. Evaluation of the spatial localization abilities for a sound source presented in the open field. Assessment of performance for speech recognition in noise. These evaluations are performed in subjects with symmetrical hearing, in a natural binaural condition and a monaural condition (with a plugged ear), in subjects with single-sided deafness and in subjects with unilateral CI

Considering the extent to which HAs play a role in sound perception and residual hearing preservation among patients with tinnitus and co-existing HL remains a lack of compelling extensive evidence, investigators designed this single-blind, 6-months randomized, controlled trial with two parallel groups. One is the HA treatment group, and the other is the waiting list control (WLC) group which receives no interventions during this period.

The HEAR-study pilots and evaluates a national, low-threshold screening program to detect hearing problems in Swiss adult childhood cancer survivors. Participants will conduct a hearing test in a local hearing aid shop and report about their experiences at the shop in questionnaires and interviews. The screening program will be evaluated using the RE-AIM framework.

This is a study of the feasibility of activating the auditory system by an electrode in direct contact with the cochlear nerve.

The goal of this clinical trial is to find out whether hearing test results using functional near-infrared spectroscopy (fNIRS) will help to fast-track early intervention for infants born with a hearing loss. fNIRS is a method of imaging brain activity using light. The main questions are: Can audiologists make more confident decisions about the optimal interventions at different critical points in the hearing care pathway when they are given additional fNIRS information compared to when they have standard audiology test results alone? Is the experience of their infant having an fNIRS test acceptable and comfortable for the parents or care givers?
