Deafness, unilateral

This study looked at whether a cochlear implant is a good value for people who are deaf in one ear or have severe hearing loss in one ear. Participants first tried other hearing devices, and if those didn't work, they were randomly assigned to get a cochlear implant right away or…

This study looked at whether a cochlear implant in the poorer ear can help adults with hearing loss in one ear who already use a hearing aid in the better ear. Forty adults who had trouble with standard hearing aids received a cochlear implant. Researchers measured word understan…

This study tested a new bimodal Bluetooth streaming feature for people who use a MED-EL cochlear implant in one ear and a Starkey hearing aid in the other. Ten participants tried the feature for one week and then completed a survey about their listening experience. The goal was t…

This study tested a new sound processor, the Osia 3, against the current Osia 2 model in 12 adults with hearing implants. Participants completed hearing tests and rated sound quality with both devices. The goal was to see if the new processor improves speech understanding in nois…

This study tested whether a new sound processor (Osia 3) helps adults with hearing loss or single-sided deafness hear better than the current model (Osia 2). Twenty-nine adults who already have a bone-anchored implant tried both processors. Researchers measured speech understandi…

This study tested whether a cochlear implant can help adults aged 65 and older who are deaf in one ear but have normal hearing in the other. Fifteen participants received the implant, and researchers measured how well they understood speech in noisy settings over a year. The goal…

This study tested a robotic device called iotaSOFT that helps surgeons insert cochlear implants into the ears of children with hearing loss. Twenty children aged 9 months to 12 years took part. The goal was to see if the robot is safe and works well. Researchers tracked any probl…

This study used brain scans (fMRI) to understand how the brain reorganizes itself when a person is deaf in one ear. Researchers looked at 30 right-handed adults with single-sided deafness to see how their brains process sound differently. The goal was to link brain changes with r…

This study looked at how the brains of children with hearing loss in one ear process sounds compared to children with normal hearing. Researchers used a special brain imaging technique to measure activity in the hearing parts of the brain. The goal was to understand how the brain…

This completed study used PET scans to examine brain changes in 20 people with asymmetric hearing loss who received a cochlear implant. Participants performed hearing and voice perception tests while their brain activity was measured. The goal was to understand how the central au…

This study tested whether changing the pitch and loudness settings on a cochlear implant (CI) could help people with single-sided deafness hear speech better in noisy places like restaurants. Researchers adjusted the CI programs of 45 adults to reduce the mismatch between the imp…

This completed study tested whether a virtual reality training program could improve the ability to locate sounds in people with hearing loss. 79 participants performed sound localization tasks with and without visual feedback. The goal was to see if training could reduce pointin…
