hearWHO Hearing Screening App

According to the World Health Organization, the sponsor of the app, hearWHO is based on a validated digits-in-noise technology: users are asked to concentrate, listen, and enter into their mobile device a series of three numbers when prompted. These numbers have been recorded against varying levels of background sound, simulating listening conditions in everyday life. The app displays the user’s score and its meaning and stores the outcome of the test so that the user can monitor hearing status over time. Reminders to take the test regularly can be set by users. The app can be used by individuals as well as health providers with a view to facilitating hearing screening especially in low-resources settings.
