Active clinical trials for "Hearing Loss"

The purpose of this study is to test the effectiveness of a community health worker intervention to expand access to hearing health care among older adults facing health disparities.

The following research questions will be investigated: What is the knowledge of medical interventions for moderate to severe hearing loss and what is the knowledge of the reimbursement criteria for hearing implants of otorhinolaryngologists in a secondary setting in Brabant. This will be evaluated by means of a specific questionnaire that will be systematically gone over with the participants during an interview in the first and third phase. In a second phase, the investigators will investigate how the knowledge of medical interventions for moderate to severe hearing loss and the knowledge of the reimbursement criteria for hearing implants of otorhinolaryngologists in a secondary setting in Brabant can be increased by training the otorhinolaryngologists in a secondary setting in Brabant. In the third phase, the investigators will evaluate the knowledge of hearing implant interventions and reimbursement criteria among otorhinolaryngologists in a secondary setting.

To test the effectiveness of body-worn, digital hearing aids, model 02 which is developed by the National Electronics and Computer Technology Center, Thailand.

Investigators hope to study patients with 1 cochlear implant and who have had hearing preservation surgery and compare the changes in the brain of these patients with normal hearing patients by doing a scan of the brain when listening to speech. The information investigators collect may help investigators to understand how the brain learns to hear with a cochlear implant and whether it uses the same areas in the brain to listen as in normal hearing patients as well as predict which patients will do well with a cochlear implant as a very specialised operation is needed to insert the cochlear implant in to the ear and is done by very few surgeons in the country. After the operation, patients need several months of teaching to help them learn how to hear through the implant. Having a cochlear implant requires a lot of cooperation and time from the patient and if investigators could understand how the brain learns to hear with a cochlear implant and predict which patients do well and why then we may be able to avoid unnecessary procedures.

Main objectives The first main objective is to evaluate the non-inferiority of the ADHEAR system compared to the PONTO 3 SUPERPOWER softband system in terms of average tonal gain. The second main objective of the study is to evaluate the superiority of the ADHEAR system compared to the PONTO 3 SUPERPOWER softband system in terms of comfort. Secondary objectives Evaluate skin reactions with ADHEAR and PONTO 3 SUPER POWER on softband. Evaluate and compare perception in silence and noise with ADHEAR and PONTO 3 SUPER POWER on softband. Evaluate and compare the subjective auditory perception with ADHEAR and PONTO 3 SUPER POWER on softband. Evaluate the satisfaction and use of ADHEAR.

Pilot study to test the feasibility of translating the English language into haptics (touch sensations)

Phonak Hearing Devices pass through different development and study phases. At an early stage, feasibiltiy studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interpendency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, resulting from the pre-validation studies, they get optimized. Prior to product launch, the Phonak Hearing Systems get reviewed by a final quality control in terms of clinical trials. This is a pre-validation study, investigating improved algorithms, features, functions and wearing comfort. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

The purpose of this study is to measure the potential effects of surgical drilling noise and/or vibration exposure on the hearing in the ear contralateral to the surgical site during skull-based surgeries

This study measures sounds produced by the sensory receptors of the inner ear called hair cells. These sounds are called otoacoustic emissions and one special case the investigators are studying are called distortion product otoacoustic emissions (DPOAEs) produced by presenting two tones to the ear. If the ear is damaged by noise exposure DPOAEs are reduced. In this study the investigators are attempting to improve the DPOAE test by adding a third tone to make the test more frequency specific. Whether the third tone helps will be determined by comparing DPOAEs collected with and without the third tone to clinical audiograms. If the addition of the third tone helps then the investigators expect DPOAEs tracked as a function of frequency (DP-grams) will more closely match the clinical audiograms.

The purpose of the feasibility study is to investigate hearing performance (audiometry and speech perception) using the CI624 in a group of adults (n=15) with low-frequency residual hearing who meet inclusion criteria.
