HEARING IMPAIRMENT

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 tests whether a one-month treatment combining the allergy drug clemastine fumarate with engineered sound can improve the ability to hear speech in background noise for people aged 45-65 with age-related central auditory processing disorder (CAPD). About 344 participant…

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 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 is building a registry of 100 people with hearing loss caused by changes in the CABP2 gene. Researchers will collect hearing test results and genetic information to learn how the condition progresses over time. The goal is to better understand the disease, not to test …
