This trial tests whether a combination of an antihistamine (clemastine fumarate) and specially designed sounds can improve how the brain processes hearing in middle-aged adults with mild hearing loss. It might help if you have trouble understanding speech in noisy settings.
This study looks at how people with healthy hearing or hearing loss understand speech in different listening environments. You might join if you have normal hearing, mild hearing loss, or use a cochlear implant, and are a competent adult English speaker.
This study explores a possible condition called 'hidden hearing loss' – where you struggle to hear in noisy situations despite passing a standard hearing test. It uses a special brain-wave test (LS Chirp ABR) to see if there is a link between your brain's response and how well you understand speech in noise.
This study tests whether a gentle brain stimulation technique (transcranial stimulation) combined with listening exercises can help people who have trouble hearing speech in noise. If you are 50 or older and struggle to follow conversations in crowded places, this trial may be a good fit.
This study tests ways to improve how people perceive space in sound and understand speech when many voices are talking at once. It may help adults with normal hearing or hearing loss better follow conversations in noisy, “overlapping voices” situations.
This study tests how well people understand speech in noisy settings, comparing younger and older adults with normal hearing and older adults with hearing loss. It aims to improve our understanding of hearing aid benefits.
