Filter by:This single-blind, placebo-controlled trial will be conducted to evaluate the safety of FX-345 administered as a single intratympanic injection in adults with acquired sensorineural hearing loss. The primary objectives are to assess the local safety, systemic safety, and pharmacokinetic (PK) profile to determine systemic exposure.
The purpose of this early feasibility study is to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP stimulation) in cochlear implant recipients. This study will iteratively evaluate different parameter sets that intend to maximize hearing performance benefits within technical requirements. This study is exploratory in nature and will achieve its objectives through ongoing review and adjustment of device parameters and fitting
The goal of this study is to investigate the role of social factors on speech learning, including production and perception, in infants ranging in age from ~7-18 months. Infants have either typical hearing or sensorineural hearing loss. The main prediction of the study is that social reinforcement will engender improvements in vocal learning above and beyond gains in hearing in infants with hearing loss. As part of this study: - The parent and infant engage in a free play session in the playroom while the investigator cues the parent to say simple nonsense words; - Infants hear playback of the same words during a second phase.
Adjusting hearing aid user's real ear performance by using probe-microphone technology (real ear measurement, REM) has been a well-known procedure that verifies whether the output of the hearing aid at the eardrum matches the desired prescribed target. Still less than half of audiologists verify hearing aid fitting to match the prescribed target amplification with this technology. Recent studies have demonstrated failures to match the prescribed amplification targets, using exclusively the predictions of the proprietary software. American Speech-Language-Hearing Association (ASHA) and American Academy of Audiology (AAA) have created Best Practice Guidelines that recommend using real-ear measurement (REM) over initial fit approach and also the recent ISO 21388:2020 on hearing aid fitting management recommends the routine use of REM. Still audiologists prefer to rely on the manufacturer's default "first-fit" settings because of the lack of proof over cost-effectiveness and patient outcome in using REM. There are only few publications of varying levels of evidence indicating benefits of REM-fitted hearing aids with respect to patient outcomes that include self-reported listening ability, speech intelligibility in quiet and noise and patients' preference. Our main research question is whether REM-based fitting improves the patient reported outcome measures - PROMs (SSQ, HERE) and performance-based outcome measures (speech-reception threshold in noise) over initial fit approach. An additional research question is whether REM-based fitting improves hearing aid usage (self-reported & log-data report). Eventually, the investigators will calculate the cost-effectiveness of REM-based fitting.
Pre-market Clinical Investigation whose primary purpose is to evaluate efficacy and effectiveness of self-fitting hearing aids
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.
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.
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.
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.
This is a retrospective and prospective longitudinal study in participants with Otoferlin Gene-Mediated Hearing Loss.
