Children who live in rural areas can have a hard time getting to the doctor — much less to an audiologist’s clinic for expensive, complex tests to check their hearing. The result for too many kids is hearing loss caused by ear infections and other curable or preventable problems. That’s why ear surgeon and TED Fellow Susan Emmett is working with 15 communities in rural Alaska to create a simple, low-cost test that only requires a cell phone. Learn more about her work and how it could change the lives of children who don’t have access to hearing care.
