A smartphone app listens for ear infections with the help of a paper cone.
Developed by a team from the University of Washington, the system relies on the phone’s microphone, speaker, and a small paper cone. The cone is slipped around the speaker end and fitted into the patient’s ear, where the app sends short sound pulses into the ear canal through the cone. A specialized algorithm measures how the sounds are reflected back to the phone, identifying the possibility of fluid in the ear with an 85 percent accuracy.
The app will be developed and distributed by the team’s startup Edus Health.
