NCT ID: NCT05608161 Not yet recruiting - Clinical trials for Sudden Sensorineural Hearing Loss

Speech Perception Impairment Follow Complete Recovery of Sudden Sensorineural Hearing Loss

Start date: November 10, 2022
Phase:
Study type: Observational

At present, few research on the auditory perception function and possible neural mechanisms of unilateral sudden hearing loss patients with complete or partial recovery of peripheral hearing.This project evaluate the speech perception function in noise of unilateral sudden hearing loss patients with with complete and partial hearing recovery by cognitive behavioral experiments, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), and longitudinal follow-up to explore its underlying neural mechanisms.

NCT ID: NCT05599165 Recruiting - Clinical trials for Hearing Loss, Sensorineural

Speech Perception in Bimodal Hearing

Start date: October 25, 2021
Phase: N/A
Study type: Interventional

The protocol has two aims; Aim 1 involves two experiments and Aim 2 involves three experiments. Under Aim 1, the investigator will identify that the frequency and time ranges of consonants produce consonant enhancement (i.e., "target frequency range" and "target time range", respectively), and that the frequency and time ranges of consonants cause consonant confusions (i.e., "conflicting frequency range" and "conflicting time range", respectively). Aim 2 tests the effects of the frequency and time ranges, identified through Aim 1 on consonant recognition with each of the four signal processing conditions: no signal processing (i.e., control condition), the target frequency and time ranges intensified alone, the conflicting frequency and time ranges suppressed alone, and both target range intensification and conflicting range suppression.

NCT ID: NCT05593484 Recruiting - Hearing Loss Clinical Trials

School Screening and Telemedicine Specialty Referral to Address Childhood Hearing Loss in Rural Alaska

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

The prevalence of childhood hearing loss in rural Alaska is disproportionately high and predominately infection-related. With preventive screenings and access to health care, much of childhood hearing loss is preventable. Although state-mandated school screening helps identify children with hearing loss, loss to follow-up is pervasive and exacerbated by a scarcity of specialists in rural regions. A mixed methods cluster randomized trial conducted in northwest Alaska demonstrated that telemedicine can significantly reduce loss to follow-up. This stepped wedge trial, in partnership with Southcentral Foundation, will build on this existing work to develop a model that can be scaled in diverse environments. We will adapt and implement a new telemedicine intervention called Specialty Telemedicine Access for Referrals (STAR). This trial will be conducted in 3 regions in rural Alaska that represent multiple healthcare systems. Based on stakeholder feedback and evidence generated from the previous trial, an enhanced mobile health (mHealth) hearing screening will be implemented in all participating schools prior to the STAR intervention, and the telemedicine referral to specialty care (STAR intervention) will be moved from the clinic directly into the school. This stepped-wedge cluster randomized trial is part of a larger hybrid type 1 effectiveness-implementation trial. The stepped wedge trial will evaluate the effectiveness of the STAR intervention in reducing loss to follow-up from referred school hearing screening in 3 regions of Alaska: Kodiak, Petersburg and Lower Yukon (n=23 schools, ~2,015 K-12 students/year). The STAR Intervention will be compared to the standard referral of a letter home to families. Cluster randomization at the level of school will be performed, with schools (clusters) randomized to one of two sequences. The effectiveness outcome (i.e., proportion of children who receive follow-up) will be evaluated over three academic years (2023-2026), with STAR rolled out in a stepwise manner for each of the two sequences (academic year 2024-2025 for sequence 1 and academic year 2025-2026 for sequence 2). The control periods for each sequence will be academic year 2023-2024 for sequence 1 and academic years 2023-2024 and 2024-2025 for sequence 2. Enhanced screening will be rolled out to both sequences at the same time (i.e., non-randomized) beginning academic year 2023-2024. An implementation evaluation will be conducted to refine and adapt the enhanced hearing screening and STAR intervention throughout the trial. Implementation data will be collected starting academic year 2022-2023 and then annually for each of the subsequent years.

A Monocentric Study Evaluating Pupillometry as an Objective Measurement for CI Fittings

PupillOM
Start date: May 2, 2023
Phase: N/A
Study type: Interventional

This trial is a monocentric, prospective and controlled study of the pupil response to detect hearing threshold and comfortable loudness of normal-hearing (NH) and CI-subjects.

NCT ID: NCT05582408 Completed - Hearing Loss Clinical Trials

Evaluation of Novel Noise Reduction Principles in Hearing Instruments

Start date: September 12, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05582148 Not yet recruiting - Clinical trials for Hearing Loss, Sensorineural

Meniere Disease and Hearing Aids

MMA
Start date: November 15, 2022
Phase: N/A
Study type: Interventional

Patients with unilateral Meniere Disease often a distortion that causes difficulties to provide hearing aids to these patients. Those patients have two main problems: disorders in noise comprehension due to interaural threshold difference and increase in the distortion during dizziness crisis. Due to these problems, some people cannot be fitting with hearing aids because the compression needed is too high or the discomfort in noise is not bearable for patients. Our aim is to evaluate and to propose a way to adjust hearing aids to restore binaural hearing with comfort.

NCT ID: NCT05572073 Recruiting - Clinical trials for Sensorineural Hearing Loss, Bilateral

Otoferlin Gene-mediated Hearing Loss Natural History Study

Start date: July 14, 2022
Phase:
Study type: Observational

This is a retrospective and prospective longitudinal study in participants with Otoferlin Gene-Mediated Hearing Loss.

NCT ID: NCT05568329 Recruiting - Clinical trials for Sensorineural Hearing Loss

Appreciation for Music Processed by Hearing Aids

Start date: September 21, 2022
Phase: N/A
Study type: Interventional

Normal-hearing participants aged 18-25 with and without musical training will listen to a series of short musical samples that have been recorded through hearing aids. The music will be played at a comfortable listening level. Subjects will use the computer to rate the sound quality of the music on a 7-point Likert scale.

NCT ID: NCT05566353 Recruiting - Hearing Loss Clinical Trials

Telemonitoring in Cochlear Implant Patient Care

EMPSICOT
Start date: December 20, 2022
Phase: N/A
Study type: Interventional

Following a sufficient delay after the cochlear implantation and initial implant activation, the patient will return to the hospital for follow-up visits for equipment maintenance and auditory performance evaluation only once per year. This frequency might appear either insufficient, in which case an additional patient check-up will be arranged, or excessive if patient performances and implant adjustments are stable. Using at-home testing tool for remote hearing performance monitoring can thus appear advantageous for both patients and clinicians, allowing to avoid an unnecessary journey to the implantation reference center for the first and to diminish a number of unscheduled medical appointments for the second.

NCT ID: NCT05561335 Recruiting - Hearing Loss Clinical Trials

Preference Comparisons for Algorithms to Hear Speech

Start date: March 21, 2023
Phase: N/A
Study type: Interventional

Twenty people with hearing impairment will be tested and fitted binaurally with hearing aids. During a real-world listening situation, each participant will be asked to compare one program with a novel algorithm to one with a standard microphone configuration. They will provide ratings on a range of outcome measures including overall preference and awareness of background noise. Overall and specific preferences for the different programs/algorithms will be determined by their subjective responses to determine if there is a significant difference between the two programs.
