Filter by:The objective of this study is to examine whether ABO and Rhesus (Rh) blood group systems have an association with distortion product otoacoustic emission (DPOAE) and transient otoacoustic emission (TEOAE) amplitudes with the hypothesis of blood groups may affect hearing thresholds.
Cochlear implants (CIs) are devices that partially restore hearing for people with severe to profound hearing loss. This research focuses on CI users who use bilaterally implanted devices (two CIs, one on each side) and also "single-sided deafness" (SSD) CI users who use one CI together with good acoustic hearing in their opposite ear. The goal is to measure and understand the impact of large input asymmetries across the two ears. These asymmetries are common in BI-CI listeners and always present in SSD-CI users. Although most CI listeners benefit from a second source of auditory input, this project measures how these asymmetries limit speech understanding and spatial hearing. The long-term goal is countering or compensating for input asymmetries. Electrophysiological measures are used to describe the health of the auditory system. Behavioral measures are used to assess if training improves performance. CT imaging is utilized to describe the placement of the CIs.
This is a retrospective study designed to collect speech perception results for HiRes Ultra CI and HiRes Ultra 3D CI users as measured in the clinical routine and to confirm the performance of these devices.
This is a retrospective study designed to collect long-term speech perception results for cochlear implants recipients using electro-acoustic-stimulation as measured in the clinical routine and to confirm the performance of sound processors associated with acoustic earhooks.
This study aims to investigate the effect of stimulation parameters and different electrode modes on speech perception in adult cochlear implant recipients.
This study aims to evaluate the safety and efficacy of cochlear implantation for adults with bilateral sensorineural hearing loss who currently do not meet the FDA-approved indications for cochlear implantation. Following cochlear implantation, participants will complete speech perception assessments and questionnaires over the course of seven visits.
Evaluation of the diagnostic and prognostic efficacy of nuclear magnetic resonance imaging in patients with acute sensorineural hearing loss or in patients suffering from probable or definite MD. The neuroradiological and audiological evaluation are held on in the same day in order to better clarify the radiological and clinical correlates.
The goal of the study is to determine the benefit of using an ECochG-based corrective action guide during cochlear implant surgery compared to the traditional surgical approach without ECochG surveillance and guidance.
The goal of this 2 step-up, exploratory study is to test safey, tolerability and PK/PD profiles in healthy volunteers and safety, tolerability and efficacy in sudden sensorineural hearing loss patients as an early salvage therapy. The main questions it aims to answer are: 1. whether is it safe and tolerable when healthy volunteers and sudden sensorineural hearing loss patients take multiple doses of NS101 against FAM19A5 2. whether is it effective in reversing hearing capability in sudden sensorineural hearing loss patients who fails to show sufficient recovery despite of oral standard steroid therapy. Patients and heathly volunteers will be given NS101 15mg/kg or 30mg/kg systemically less than 3 months per protocol. This is placebo controlled, double blinded study, which means there will be a group who receives placebo (i.e. fake drug) for study purpose.
The proposed field trial will clarify the real-world effectiveness of HAs in remediating deficits in emotion processing for older adults with mild-to-moderate hearing loss. This study will employ a repeated reversal design to establish baseline affective state without HAs, when wearing amplification, and after HAs are removed. This study will triangulate self-report, behavioral, and physiological measures to capture nuances of emotional processing in the laboratory and in daily listening. Naturalistic stimuli will be used as it occurs in daily life to elicit emotional experiences, and ecological momentary assessment and commercially-available wearable sensors will be used to track changes in emotional state in daily listening. Anchoring real-world emotional experiences with controlled laboratory experiences will validate wearable sensors. Additionally, laboratory emotional stimuli will be related to real-world emotional experiences to establish the utility of laboratory stimuli in future studies. It is likely that benefits in emotional processing will have differential effects based on individual characteristics (such as degree of hearing loss, age, gender, cognitive ability, and personality), so participants will be analyzed according to larger groupings based on individual differences.
