This study tests whether a custom 3D-printed ear tip is more comfortable than a regular one for people with hearing loss. If you wear hearing aids or are considering them, this could help make the fit better.
This research study tests a new way to measure how well your middle ear (the tiny bones behind your eardrum) works using sound waves instead of traditional hearing tests. It involves three groups: people with normal hearing, people with conductive hearing loss, and people scheduled for cochlear implant surgery.
This study compares two types of non-surgical hearing devices that use bone conduction to help you hear. It aims to find which device works better for people with normal inner ear function but who need alternative ways to hear.
This study tests flexible hearing aids for people with conductive or mixed hearing loss (where sound is blocked or not transmitted well to the inner ear). It aims to see if these devices work well and are comfortable for daily use.
This study tests if a cochlear implant fitting based on your ear's anatomy helps you hear speech in noisy places and enjoy music more. It is for people who are deaf in one ear and use a MED-EL cochlear implant.
This study compares two different ways of fitting hearing aids for Veterans who were exposed to blasts and now have hearing difficulties. The goal is to see which method works better for improving hearing and understanding speech.
