A Computational Approach to Optimal Deactivation of Cochlear Implant Electrodes
Hearing LossThe goal of the present study is to use computationally driven models of speech understanding in CI users to guide the search for which combination of active electrodes can yield the best speech understanding for a specific patient. It is hypothesized that model-recommended settings will result in significantly better speech understanding than standard-of-care settings.
Individually-guided Hearing Aid Fitting
Hearing LossThis translational project aims to optimize the fitting of hearing aids by development and clinical validation of a toolset that guides signal processing choice based on the individual auditory and cognitive abilities of the patient. The clinical trial portion of the project will validate clinical use of the toolset by comparing a population of patients fit with the toolset to those fit using current standard of care. Data will be collected on patient outcomes, clinical impact (number of visits needed to adjust the hearing aids) and audiologist feedback regarding professional confidence. Clinician feedback will also be collected to refine implementation of the clinical application and improve its usability. It is hypothesized that hearing aid fittings completed using the clinical toolset will result in better patient outcomes, fewer post-fitting visits and a higher level of clinician confidence compared to standard-of-care hearing aid fittings.
A Feasibility Study Evaluating the Performance of Focused Multipolar Stimulation in Adult Cochlear...
Hearing ImpairmentThis feasibility study is designed to explore several facets of hearing performance that may show improvements for alternative modes of stimulation compared to Monopolar (MP) stimulation within a group of adult cochlear-implant recipients. Measures of speech recognition, music appreciation, listening effort, quality of life, and real-world assessments will be gathered to determine the most promising benefits for further examination.
Oral Statins and Protection From Hearing Loss
Sudden Sensorineural Hearing LossA small clinical trial for idiopathic sudden sensorineural hearing loss (ISSNHL). Will the addition of an oral statin to the standard treatment (oral methylprednesolone and the salvage therapy of intratympanic dexamethasone) improve the treatment outcome for patients with ISSNHL? This study will compare the two treatments and quantitatively evaluate hearing and speech discrimination and have the patients subjectively evaluate tinnitus.
Evaluation of Unilateral vs Bilateral Hearing Aids for the Treatment of Age-related Hearing Loss...
Hearing LossThis study aims to evaluate the benefit of bilateral hearing aid use compared to a unilateral hearing aid. Patients with mild to moderate bilateral hearing loss who are considering the purchase of a commercially available hearing aid will be considered for participation. Eligible participants will be randomized to one of the following treatment arms: (1) a bilateral hearing aid fitting group, and (2) a unilateral hearing aid fitting group.
Study of a Signal-processing Algorithm Aiming at Improving Speech-in-noise Intelligibility in Normal-hearing...
Speech Intelligibility in NoiseNearly half a billion people suffer from disabling hearing loss. The most common form of hearing loss in adults is age-related hearing loss (ARHL), which causes a reduced ability to understand speech in noisy environments. The ability of people with ARHL to communicate is therefore greatly impacted, limiting their social interactions and thus their quality of life. Yet, the wear of hearing aids - which is the current standard rehabilitation treatment in such cases - does not lead to optimal satisfactory outcomes when it comes to understanding speech in noisy environments. The objective of this pilot study is to test a new signal-processing algorithm, based on artificial intelligence, that aims at enhancing the intelligibility of speech-in-noise signals. The efficiency of the algorithm is compared to a standard denoising algorithm commonly used in hearing aids. The primary outcome measure is the word-identification performance of the participants, using the FrMatrix test (Jansen et al., 2012). Two secondary outcome measures are investigated: listening effort (self-assessed using a Likert scale, and measured through response times), and subjective preference (assessed in a paired-comparison task). The study is conducted in 20 normal-hearing subjects and in 40 older (age ≥ 55 years) hearing-impaired subjects.
Clinical Utility of Residual Hearing in the Cochlear Implant Ear
Hearing LossSensorineural3 moreThe current study is a randomized multi-center clinical trial that investigates the role an intraoperative hearing monitoring system (electrocochleography) has on helping to save residual hearing in patients undergoing cochlear implantation (CI).

Hearing LossSuddenThe investigators enrolled patients with total sudden deafness who had failed treatment with systemic combined intra-dural hormone injections. The patients were randomly divided into a pilot group and a control group for a randomized controlled clinical study, with the pilot group receiving a round window niche enlargement via round window inner ear administration and the control group receiving regular intra-drum injection hormone therapy

The Impact of Hearing Loss Severity on Balance Intervention Outcomes
Hearing LossFall1 moreThe goal of this study is to learn about how hearing loss impacts balance intervention outcomes and risk of falling in older adults. The main questions it aims to answer are: How does the evidence-based A Matter of Balance (AMOB) program affect older adults' falls risk and balance-related measures? Is the severity of someone's hearing loss related to their balance intervention (AMOB) outcomes? Participants will: Complete a hearing and balance test Answer some questions about their background and health history, their thoughts about potential falls and how this impacts them, and their current physical activity level Participate in the A Matter of Balance Program, an evidence-based program that includes group discussion, activities, and exercises to reduce fall risk
