Because newborn babies are non communicative, it’s difficult to diagnose issues with hearing. According to a recent Medgadget article, researchers at the University of Washington developed an accessible new hearing test for newborns that uses a smartphone and cheap earbuds. The earbuds are connected to a small microphone that can listen to the vibrations of hair cells. The sounds are relayed to a smartphone app for analysis and instructs the user to visit a specialist in the case of abnormal results.
