Active clinical trials for "Hearing Loss"

The investigators are studying a new way of doing cochlear implant surgery called "Percutaneous Cochlear Implantation". In this surgery, instead of doing a mastoidectomy where about 30ml of bone is removed, the investigators use image-guided technology (similar to GPS systems used to guide automobile travel) to drill directly from the surface of the skull to the cochlea, removing less than 2ml of bone. To use this technique, three markers (or anchor screws) are screwed into the bone around the ear. Next, an x-ray of the head (called a CT scan) is taken. Using this CT scan, a path to the inner ear (cochlea) is planned and a drill guide (Microtable) is made that mounts on the anchor screws. A drill will be attached to the guide and used to drill a path from the surface of the skull to the inner ear (cochlea). The implant electrode will be threaded through this path. All of these procedures take place under general anesthesia.

The purpose of the study is to evaluate the score of the Evaluation of the Impact of Deafness in Adults(ERSA)/150 questionnaire obtained at 3 months compared to the inclusion score.

Adult hearing loss in is the third most common chronic health condition in the United States. Adults living in rural areas face a higher risk of experiencing hearing loss, and more difficulty receiving testing and treatment than adults in urban settings. The goal of this clinical trial is to develop and test a community-based hearing healthcare patient navigation program in rural Kentucky. The main question this study aims to answer is: -Can the number of rural adults receiving diagnostic hearing tests be increased?

Age-related hearing loss (ARHL), like neurodegenerative diseases, appears insidiously with age. As major public health issues, they are nonetheless under-diagnosed because the presence of one can hinder the objectification of the other. The CogAudio project aims to detect early and in an ambulatory mode in a memory centre a speech perception disorder in noise thanks to the VRB test in patients weakened by cognitive disorders.

In this study, the investigators are testing whether cognitive training can lead to improvements in speech perception for individuals with hearing loss. Individuals will complete 20 hours of cognitive training that is designed to improve cognitive abilities such as short term memory and attention. The investigators predict that cognitive training that improves the cognitive abilities affected by hearing loss will improve speech perception.

The aim of this study is to investigate the clinical benefit for patients implanted with the Nucleus® CI532 cochlear implant. The Nucleus® CI532 has a pre-curved, perimodiolar array, the EA32, which is introduced into the cochlea through a straightening sheath.

Hearing loss has been associated with decreased emotional wellbeing and reduced quality of life in aging adults. Although hearing aids can target aspects of peripheral hearing loss, persistent perceptual deficits are widely reported. One prevalent example is the loss of the ability to perceive speech in a noisy environment, which severely impacts quality of life and goes relatively unremediated by hearing aids. Musicianship has been shown to improve aspects of auditory processing, but has not been studied as a short-term intervention for improving these abilities in older adults with hearing aids. The current study investigates whether short-term choir participation can improve three aspects of auditory processing: perception of speech in noise, pitch discrimination, and the neural response to brief auditory stimuli (frequency following response; FFR). Sixty hearing aided older adults (aged 50+) recruited from the Greater Toronto Area will be randomly assigned to one of three conditions: a choir singing class (n=20), a music appreciation class (n=20), and a do-nothing control group (n=20). Choir participants will take part in a singing class for 14 weeks, during which they will take part in group singing (2 hours/week) supported by individual online musical training (1 hour/week). Participants will undergo pre- and post-training assessments, conducted during the first week of the choir class and again after the last week. Participants in the music appreciation class will be involved in 14 weeks of music listening classes, and the do-nothing control group will not engaged in an active intervention. All participants will undergo the same battery of assessments, measured before and after the 14-week time frame. Auditory assessments (speech perception in noise and pitch discrimination tests) will be administered electronically, and the FFR will be obtained using electroencephalography (EEG). Each of the four assessment sessions (two pre-training, two post-training) will last approximately 1.5 hours, for a total of 6 hours of data collection. The goal of this research is to investigate whether short-term musical training will result in improved auditory outcomes for older adults with hearing aids. It is predicted that the choir singing group will demonstrate the greatest improvements across all auditory measures, and that both the choir singing and musical appreciation groups will experience greater improvements than the do-nothing control group.

The purpose of this feasibility study is to evaluate whether low-frequency acoustic hearing sensitivity can be preserved in newly implanted adults with partial deafness (considerable low frequency acoustic hearing profiles with severe-to-profound high frequency sensorineural hearing loss) using the HiResolution™ 90K™ Advantage cochlear implant with the HiFocus™ Mid-Scala electrode to support the development of electro-acoustic stimulation technology (EAS).

The purpose of this study is to determine the feasibility of preserving low-frequency acoustic hearing in adults with a moderate degree of hearing loss in the low frequencies and severe-to-profound hearing loss in the mid-to-high frequencies who are implanted with the HiRes™ 90K Advantage implant with HiFocus™ Mid-Scala electrode.

The purpose of this research study is to learn about the hearing outcomes of adult and pediatric patients who are treated with or are candidates for bone conductive devices (also termed "BAHA"). Hearing outcomes will also be assessed with a second audio processor device called the Adhear System.
