Filter by:Study of freedom sound processor users that upgrade to N6 sound processor CP900 series. To test speech understanding in each device and usability of upgrade.
Collection of normative voltage tomography data during and/or immediately after electrode insertion into the cochlea using Surgical Assistant (SA16) research software and postoperatively at activation, three and twelve months post-activation with CS19 research software in adults who are receiving a Cochlear Nucleus CI512, CI422, CI522 or CI532 cochlear implant.
The aging of the population, and greater exposure to noise, are responsible for an increased incidence of hearing loss (presbycusis). This hearing loss is sensorineural disability that has become a real public health problem. The main means of rehabilitation of this disability is represented by the apparatus of patients with conventional hearing aids. However, these hearing aids have several drawbacks that limit their profits, often abandoning the prosthesis by the patient. Middle ear implants were developed to answer these problems. They are intended to amplify the sound signal by transmitting directly to the middle ear to compensate for the hearing loss and are indicated in case of failure or contraindication of conventional equipment. However, these middle ear implants currently have limitations as performance failure. Recent data show that the performance of the ossicles repair techniques are dependent on the coupling of the ossicular prosthesis to the ossicles. Furthermore, advances in the understanding of the biomechanics of the ossicles confirm the importance of the placement and linkage of surgical restoration processes. This data can be applied to middle ear implants to improve performance. Indeed, a preliminary experimental study on anatomical parts, using analysis of the vibration of the middle ear structures by laser velocimetry, allowed the investigators to define the transducer placement method and coupling method to ossicles. Investigators wish to validate in vivo results in a pilot study on a small number of patients by comparing two surgical techniques guided by velocimetric measures.
Most of us will experience some degree of hearing loss as we get older. It can affect one or both ears and without treatment causes difficulty with following conversations in the home or workplace. Audiologists are trained to diagnose and treat hearing loss and tinnitus problems. They also dispense, and fit hearing aids. Physicians do not provide or fit hearing aids directly, however they diagnose hearing loss and can recommend hearing aids amongst other treatments for hearing loss. It is undecided whether consulting with a physician in addition to an audiologist will improve user's satisfaction with hearing aids, compared to consulting with an audiologist alone. The purpose of this study is to determine whether physician involvement (in addition to an audiologist) in the hearing aid fitting process improves users' satisfaction with hearing aids. The study utilizes questionnaires to assess satisfaction with hearing aids. Furthermore, participants decision to keep the purchased hearing aids will be recorded. The study will take place in the clinics of family doctors, Otolaryngology (Ear) surgeons and audiologists. A hearing aid suitable for the needs of the participant will be fitted by an audiologist. In the first 21days after the fitting, participants will attend follow-up visits with the audiologists for adjustments to the hearing aids to best meet their specific listening needs. After 21 days, eligible participants will be allocated to either the Control or Test groups. Participants in both groups will be asked to describe the change in their hearing performance related to the use of hearing aids to their audiologist(Control) or Physician (Test) at a follow-up visit. At the study's final visit, participants will be asked to complete a satisfaction-based questionnaire. The time taken to fit a hearing aid varies depending on the individual needs of the patient. It is estimated that at most 10 visits will be required over 90 days to complete the hearing aid fitting and study processes. These visits will be of 30 minutes duration on average, except for the initial and final visits which lasts for 45 minutes. A patient will spend a maximum of 330 minutes to complete the hearing aid fitting process, but only 25 minutes of this time will be specifically related to the study. The study is intended to determine the satisfaction with hearing aids and consultations with health professionals.
This RCT will have two arms: A control group that receives the standard of care from audiologists and an experimental group that receives both the standard of care and the at-home use of the TELLYHealth intervention. Subjects in each group will complete questionnaires at enrollment, mid-study and at the end of the study.
The objective of this pilot study is to explore whether repeat doses of AUT00063 can provide an indication of improvement in performance of tests across a battery of speech and hearing assessments in cochlear implant users.
The NC NEXUS research study is exploring the utility of next generation sequencing in newborn screening and parental decision making. The National Institutes of Health (NICHD and NHGRI) are co-funding this study under a single U-19.
The purpose of this feasibility study is to evaluate the benefit of unilateral implantation in adults who have severe to profound sensorineural hearing loss in one ear, and up to moderate sensorineural hearing loss in the other ear (asymmetric hearing loss).
People with the congenital anatomical malformation known as "Enlarged Vestibular Aqueduct" (EVA) may experience decline in hearing ability. This is an online registry to gather patient experiences with EVA, with the goal of providing future researchers with the information necessary to better evaluate and make recommendations for patients with EVA. Data will be obtained from volunteers who enroll and submit their information on a website, https://eva.uhhospitals.org, and a limited data set may be provided to researchers interested in analyzing repository data. The limited data set would not contain any identifiable information except for ages, dates such as date of diagnosis, or city/state of residence.

The overall aim of the study is to compare the verification accuracy and hearing-aid outcomes between the traditional, fitting approach where the patient is present during the visit and a coupler-based fitting approach where the patient is not present and mailed their hearing aids. If the coupler-based fitting protocol tested in this study as effective as the traditional fitting protocol, then patients receiving replacement hearing aids may circumvent a face-to-face visit.
