This study tests an auditory brainstem implant in 20 children who are deaf because they are missing the inner ear or the nerve that carries sound to the brain. The device is surgically placed to stimulate the brainstem directly, bypassing the missing parts. Researchers will monit…

This study compares two common hearing screening methods—pure-tone audiometry and otoacoustic emissions—in over 13,000 preschool children. The goal is to determine which method is better at identifying hearing loss early, so children can get the help they need to avoid speech and…

This study tests whether acetylcysteine, a drug often used for other purposes, can prevent hearing loss caused by cisplatin chemotherapy. About 40 adults receiving high-dose cisplatin will get either acetylcysteine or a placebo after each chemo session. Researchers will measure h…

This study is testing whether changing the frequency settings on a cochlear implant can improve sound quality and speech understanding for people who use both a cochlear implant and a hearing aid. Thirteen experienced bimodal users will try an experimental frequency setting for o…

This study is testing whether changing the low-frequency settings on a cochlear implant can improve hearing for people who are deaf in one ear but have normal hearing in the other. Twenty-two adults will try four different sound maps during their first month after implant activat…

This study tests a new way for hearing aids to process soft sounds, aiming to make quiet speech clearer. Sixteen adults with hearing loss will try two different hearing aid settings in a lab and rate which one sounds more natural and understandable. The goal is to improve hearing…

This study tests whether automatic sound processing in cochlear implants helps children with hearing loss understand speech in noisy environments. Twenty children aged 6 to 16 who use cochlear implants will compare three different sound settings. The goal is to see which setting …

This study tests whether a new AI-based noise reduction feature in Phonak hearing aids helps people with hearing loss or cochlear implants hear speech more clearly in noisy settings. Researchers will measure how well 500 participants repeat words and sentences in quiet and noisy …

This study is testing a new software algorithm called SEDA that reduces background noise for cochlear implant users. Researchers will measure how well 60 participants (ages 12 and older) understand speech in quiet and noisy settings with and without the algorithm. The goal is to …

This study tests a new hearing aid, Audiocap, in 100 adults with mild-to-moderate hearing loss who have never used a hearing aid before. The goal is to see if it improves hearing better than a placebo device after one month of use. Participants will undergo standard hearing tests…

This study compares using virtual reality glasses versus the standard 'show-do' technique to reduce dental anxiety in 54 children with moderate to severe hearing impairment. The children will have their pulse and anxiety scores measured during a dental cleaning. The goal is to se…

This study tests whether community healthcare workers can effectively fit hearing aids using a smartphone app in low- and middle-income communities. 90 adults with mild to severe hearing loss will be randomly assigned to receive either a smartphone-based fitting, a pre-set fittin…

This study analyzes dried blood spots from 630 newborns to find protein and RNA markers that could predict which babies with congenital CMV will develop hearing loss or other problems. Researchers will compare samples from infected babies who had complications, those who did not,…

This study will follow 5,000 children and teens with hearing loss and normal hearing over time. Researchers will measure changes in hearing, speech, language, and brain scans to see how different treatments—like hearing aids, cochlear implants, or gene therapy—affect development.…

This study looks at how people with normal hearing, hearing loss, or cochlear implants use nearby sounds to recognize speech. Researchers will test participants' ability to identify words and sentences in quiet and noisy settings. The goal is to better understand how hearing aids…

This study tests a patient navigation program to help rural adults in Kentucky get hearing tests. 500 participants from primary care clinics will receive guidance every two weeks to overcome barriers like travel and cost. The goal is to see if more people complete diagnostic hear…

This study looks at how people with hearing aids perceive the timbre (quality) of sounds and understand complex sound scenes, like music or crowded rooms. Researchers will compare 75 adults aged 60-75 with and without hearing loss. Participants will listen to sounds and rate how …

This study aims to improve how children with cochlear implants perceive sound by testing new sound coding strategies. Researchers will compare hearing performance between children and adults, and between those with implants and those with normal hearing. The goal is to understand…

This nationwide study aims to understand how hearing loss affects thinking, language, reading, and emotional wellbeing in 256 deaf or hard-of-hearing adolescents. Researchers will use tests and questionnaires to measure speech perception, cognitive skills, and school burnout. No …

This study is gathering information from 100 children and adults who use MED-EL hearing devices, including implants and non-implantable devices. Researchers will collect data on hearing ability, speech understanding, and quality of life through tests and questionnaires. The goal …

This study aims to understand why people with Turner syndrome often lose their hearing. Researchers will look at genetic and epigenetic markers in 150 adults aged 18-60. Participants will have hearing, balance, blood, and imaging tests. The goal is to find new ways to treat or de…

This research study looks at how children and adults who use cochlear implants or auditory brainstem implants hear and understand sounds. Participants will listen to words, sentences, and tones to see how well they identify speech and tell differences in loudness or pitch. The go…

This study looks at whether inner-ear balance (vestibular) problems make reading harder for children with hearing loss. Researchers will test 90 children, some with normal hearing and some with severe hearing loss, measuring their ability to see clearly during head movements and …

This study follows 19 adults with hearing loss who already received a cochlear implant that releases a steroid to reduce inflammation. Researchers will check how well the implant works over 5 years by measuring electrical signals and tracking any side effects. The goal is to see …
