NCT ID: NCT05923203 Recruiting - Hearing Loss Clinical Trials

Combined Electric and Acoustic Hearing (EAS) in Children and Adults

Start date: December 5, 2022
Phase: N/A
Study type: Interventional

Cochlear implants are surgically implanted devices which restore the ability to hear to the hearing impaired. Improvements in surgery and electrodes have results in an increased number of adults and children who have residual hearing and can benefit from electric and acoustic hearing in the same ear. This is called Electric Acoustic Stimulation (EAS). Many studies have shown that adult EAS users show significant benefits for speech understanding in noise and spatial hearing tasks as compared to a CI paired only with a contralateral HA. Even though this type of hearing is becoming more common, there is limited research on how it can be beneficial to children with CIs. The benefits of this study are a greater understanding of the participant's speech understanding, binaural processing, and spatial hearing. The results will help audiologists and researcher better understand how cochlear implants work, specifically when using electric and acoustic hearing in the same ear.

NCT ID: NCT05917496 Not yet recruiting - Clinical trials for Cochlear Implantation

Analysis of Parental Support in Families Using the LENA After Early Cochlear Implantation

ACLEIC
Start date: July 2024
Phase:
Study type: Observational

The language environment that influences the child's language development has been studied using different subjective tools, mainly audio and/or video recording and manual transcriptions. The linguistic results of the implanted deaf child are dependent on the age at the implant, but also on the auditory and linguistic stimulation in the first months following the placement of the implant. Parents are the main actors in the child's language development. Professionals can rely on the LENA tool: Language ENvironment Analysis, which objectifies the language environment of the child at home in his daily environment. It is possible to obtain statistics on the number of adult words received by the child, the number of words produced by the child as well as the exposure to media and noise. On the basis of this quantitative data, the family can be supported in an attempt to optimize the conditions for receiving their child's speech. The purpose of this study is to analyze the effect of speech therapy parental support using the data provided by the Language ENvironment Analysis (LENA) tool, in a pediatric population implanted early, i.e. before the age of 18 months and aged under 24 months inclusive at the start of their participation in the study.

NCT ID: NCT05898659 Recruiting - Clinical trials for Sensorineural Hearing Loss, Bilateral

Comparison in New Cochlear Implanted Subjects of a Tonotopy-based Bimodal Fitting With or Without Synchronization

Start date: October 17, 2023
Phase: N/A
Study type: Interventional

Main objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy with synchronization between HA and CI (ABFS) to a tonotopy based fitting strategy without synchronization (ABFnoS) for the accuracy of sound localization. Secondary objectives: Comparison of ABFS to ABFnoS for the bias of sound localization. Comparison of ABFS to ABFnoS for speech perception in noise. Comparison of ABFS to ABFnoS for the auditory skills experienced by the subject.

NCT ID: NCT05893992 Not yet recruiting - Hearing Loss Clinical Trials

fNIRS, Listening Effort, and Motivation

Start date: August 2023
Phase: N/A
Study type: Interventional

The purpose of the current study is to measure oxygenation in the PFC using fNIRS in a sample of older adults with hearing loss. Participants will be instructed to listen to sentences in noise at a challenging signal-to-noise-ratio, and to indicate what they heard using a closed-set response interface. Participants will complete 4 sessions: a training session, and a session for each condition. During each test session, participants will be instructed to listen to at least 100 sentences. Oxygenation, response times, and listening accuracy will be measured throughout.

NCT ID: NCT05892731 Active, not recruiting - Depression Clinical Trials

Study of Cognitive Reserve Disorder Affecting Depression in Aged Related Hearing Loss Via Rest State EEG

Start date: February 8, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05870527 Enrolling by invitation - Hearing Loss Clinical Trials

Pupillary Dilation During Post-Auricular Vagal Nerve Stimulation

Start date: July 10, 2023
Phase: N/A
Study type: Interventional

The research team will evaluate pupillary dilation from vagal nerve stimulation of Arnold's Nerve, a branch of the vagus nerve, during routine cochlear implantation surgery.

NCT ID: NCT05869266 Completed - Hearing Loss Clinical Trials

Tuned App Self-Fitting vs. Professional Fitting

Start date: May 1, 2023
Phase: N/A
Study type: Interventional

The aim of the study is to compare the perceived outcome of the self-fitting performed by the participants using the Tuned mobile application with the traditional professional fitting as performed by a licensed professional audiologist in subjects with mild to moderate sensorineural hearing loss.

A Study Evaluating the Application of Hearing Aid Technologies to Signal Processing for Adult Cochlear Implant Recipients

A feasibility, prospective, multi-centre, repeated measures investigation evaluating the application of hearing aid technologies to signal processing for adult cochlear implant recipients

NCT ID: NCT05859568 Enrolling by invitation - Hearing Loss Clinical Trials

Baseline Performance and Fitting Parameters for Sonova Products

Start date: April 17, 2023
Phase: N/A
Study type: Interventional

The purpose of this study is to assess the effectiveness and optimization of various FDA approved products.

NCT ID: NCT05855005 Completed - Hearing Loss Clinical Trials

Direct-to-Consumer Hearing Aids and Listening Effort

Start date: October 25, 2022
Phase: N/A
Study type: Interventional

The aim of this proposed project is to understand whether direct to consumer (DTC) hearing aids programmed to individual hearing losses, can reduce listening effort for effective communication. If DTC aids can provide benefits beyond amplification, then they could be an affordable option to reduce barriers to care and improve hearing aid uptake in adults with hearing loss.
