New smartphone app can hear ear infections in children

Dr. Randall Bly, an assistant professor of otolaryngology-head and neck surgery at the  91探花School of Medicine who practices at Seattle Children鈥檚 Hospital, uses the app to check his daughter鈥檚 earThe most common reason that parents take their children to a pediatrician is ear infections, according to the National Institutes of Health.

Ear infections occur when fluid builds up in the middle ear behind the eardrum and is infected. This buildup is also common in another condition called otitis media with effusion. Any kind of fluid buildup can be painful and make it hard for children to hear. Both conditions are also hard to diagnose because they have vague symptoms.

91探花 researchers have created a new smartphone app that can detect fluid behind the eardrum by using a piece of paper and a smartphone鈥檚 microphone and speaker. The smartphone makes a series of soft chirps into the ear through a paper funnel and, depending on the way the chirps are reflected back to the phone, the app determines the likelihood of fluid present with a probability of detection of 85%.
