Active clinical trials for "Hearing Loss"

The middle ear implant are used for patients with mild to severe sensorineural hearing loss, who cannot benefit from conventional hearing aids because of medical reasons such as chronic external otitis or external skin irritation. The device is also available for patients who are dissatisfied with the conventional hearing aids because of poor sound quality, feedback or occlusion of the ear canal. To date, more than 1500 patients have been implanted in Europe and about more than 600 patients in France. The aim of the present study is to compare in a randomized study the performances of the system to those of the conventional hearing aid in patients with similar degree of 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. Based on the conclusions of the first study, we have identified areas that require further analysis and testing prior to implementing of the proposed frequency response curve into our products. 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.

In the study, the speech intelligibility in noise (Outcome) between a novel noise reduction algorithm (Intervention) versus the standard noise reduction (Comparator) will be tested in adults with a N3-N4 hearing loss (Population) using streamed signals via hearing aids.

In this study, patients with aged-related hearing loss with depression and without depression were evaluated by audiometry (pure tone audiometry and speech audiometry), cognitive function assessment (MMSE scale for simple mental state test, MoCA Scale for Montreal Cognitive Assessment), and depressive symptoms assessment (GDS-15 and HAMD), resting state EEG. The ananlysis of resting state EEG included power spectral density, traceability analysis, functional connectivity, microstate, clustering coefficient, characteristic path length, characteristic path permeability, and compatibility coefficient. EEG signals were used to explore the activation of brain regions and poor connectivity of brain regions affected by cognitive reserve dissonance on the level of brain imaging. This paper innovatively explores the influence of cognitive reserve dissonance on depressive mood in senile deafness by means of audiological assessment, cognitive function assessment, depression symptom assessment, resting state electroencephalography (EEG) and other technical means. Auditory and cognitive cortical activation, functional connectivity of brain regions, small-world attributes and microstates were analyzed in senile deafness with or without depression at the brain imaging level.

This study will compare different microphone technologies in a noisy environment when the dominant speaker is at the front, back, left, or right side of the listener.

Participants with hearing loss and Tinnitus will wear hearing aids with amplification-only or with an added sound, and have their tinnitus level evaluated before and after intervention.

A methodical evaluation of novel sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and asses strength and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa

The investigators will conduct a small pilot study that will randomize ~ 40 70-84 year-old adults with hearing loss to best-practices hearing rehabilitative treatment (hearing assessment, counseling, fitting of amplification devices) versus a successful aging intervention (one-on-one counseling/education sessions on successful aging topics). Participants will be followed for 6 months, and outcomes will focus on communication, quality of life, cognition, and other functional surveys. This pilot study is in preparation for a larger planned trial to investigate if hearing loss treatment can reduce cognitive decline and dementia in older adults.

Evaluate the Cochlear™ Nucleus® S-Round Window (S-RW) implant in newly implanted adults with broader requirements to be considered an eligible candidate.
