This study tested a new cochlear implant (CI632) in 10 adults who have some low-frequency hearing but poor high-frequency hearing. The goal was to see if the implant improves speech understanding and overall hearing. Participants received the implant and were followed to measure …

This study tests whether using a special hearing-in-noise diagnostic (the ACT test) to fit hearing aids improves speech perception, spatial awareness, and user satisfaction compared to standard fitting. Adults aged 18-50 with moderate to severe hearing loss who use bilateral hear…

This study tested a hearing aid feature called AutoFocus360, which automatically points microphones toward whoever is speaking. Thirty adults with mild to moderate hearing loss listened to audio clips and compared AutoFocus360 to standard settings. The goal was to see if it made …

This pilot study tests whether a new training program called SEBAR can improve confidence and success with over-the-counter (OTC) hearing aids. Twenty-seven adults with mild-to-moderate hearing loss who have never used hearing aids will wear OTC devices for a week and answer ques…

This study tested two new features in the MED-EL SONNET 3 audio processor for cochlear implant users: the Focused Beamformer, which improves directional hearing, and the AI Mode Medium, which uses adaptive intelligence to optimize sound processing. Forty experienced cochlear impl…

This study tested whether a home-based balance therapy program is practical for children aged 4-17 with inner-ear problems that cause dizziness and balance issues. Twenty-one children did balance exercises at home for 8 weeks, with weekly check-ins from a physical therapist. The …

This completed clinical trial tested whether a dietary supplement called Tisina complex could improve cognitive health in people with mild cognitive impairment and tinnitus. About 84 adults aged 30 to 75 took either the supplement or a placebo for 90 days. Researchers measured ch…

This study tested a daily dietary supplement called ACEMg (Soundbites) in 64 adults with hearing loss or tinnitus. Participants took the supplement for 24 weeks and completed hearing tests and symptom surveys at home using a smartphone app. The goal was to see if the supplement c…

This completed study tested whether adding gastrodin acupoint injections to standard care helps people with sudden hearing loss and vertigo. One hundred adults received either standard therapy alone or standard therapy plus injections into specific acupuncture points over four we…

This study tested a new way to process sound to help people with hearing loss understand speech better, especially tricky consonant sounds. Forty adults who use both a cochlear implant and a hearing aid (bimodal users) listened to consonants processed in different ways. The goal …

This completed study tested a hearing aid that is built into a pair of glasses for adults with mild to moderate hearing loss. The goal was to see if the device helps people understand speech better in noisy settings and reduces listening effort. Twenty-one adults participated in …

This study looked at 324 people with hearing loss and an inner ear problem called enlarged vestibular aqueducts. Researchers collected DNA, hearing tests, and scans to find genes that may cause the condition. The goal was to learn more about why it happens, not to test a treatmen…

This study investigates whether a quick, painless electrical measurement called transimpedance matrix (TIM) can detect scar tissue (fibrosis) that sometimes forms inside the cochlea after cochlear implant surgery. Researchers will compare TIM results with CT scans in 180 adults w…

This study aims to find the genetic causes of hereditary hearing loss and balance disorders. Researchers will study families with these conditions, collecting medical history, blood or cheek swabs, hearing and balance tests, and sometimes scans. The goal is to identify genes and …

This study aimed to understand why people with cochlear implants vary in how well they understand speech. Researchers measured electrical interactions between the implant's electrodes in 17 adults with hearing loss. They compared these measurements to each person's ability to rec…

This study tested two different methods for programming cochlear implants in 17 adults with hearing loss. The goal was to see if a new, faster fitting method works as well as the standard one for understanding speech in quiet and noisy settings. Results will help improve how impl…

This study tested a new way to program cochlear implants in 47 children aged 4 to 12. Instead of the standard method, doctors used CT scans to see exactly where the implant's electrodes sit inside the ear, then turned off any poorly placed ones. The goal was to see if this person…

This completed study enrolled 186 people with mild to moderate hearing loss to understand how damage to inner ear sensory cells and auditory neurons affects speech understanding, especially in noisy environments. Participants were fitted with hearing aids and tested on speech rec…

This study tested a new method for programming cochlear implants called Focused Multipolar Stimulation (FMS). Researchers compared two ways to set up the implant: one using objective measurements and another based on the user's feedback. The goal was to see which approach helps a…

This completed study looked at how the inner ear responds to sound during and after cochlear implant surgery in 88 participants. Researchers used a noninvasive test called electrocochleography to measure electrical activity in the cochlea. The goal was to see if these measurement…

This study looked at how much children with hearing loss and their caregivers understand about what caused the hearing loss. Researchers asked 156 participants to fill out questionnaires about the type and cause of their hearing loss and whether knowing the cause matters to them.…

This study aimed to better understand hearing loss by measuring electrical signals from the hearing nerve during brain surgery. Researchers studied 19 patients with normal hearing or hearing loss to see how nerve fibers respond to sound. The goal was to improve a computer model o…

This study looked at 49 adult cochlear implant users to see if electrical measurements from the inner ear can predict the best sound levels for each person. Researchers collected data during surgery and after months of implant use, then compared it to standard hearing tests. The …

This study tested a home-based reading program called Sit Together and Read (STAR) in 15 preschoolers with hearing loss. Caregivers read with their child for 15 weeks using special techniques to teach print concepts and letter knowledge. The goal was to see if the program is feas…

This study looked at whether a person's thinking skills affect how much they benefit from hearing aids. Researchers tested 32 first-time hearing aid users aged 45-80, adjusting features like frequency compression or noise reduction. The goal was to see if customizing settings bas…
