Now children with ear infection can be detected with the help
of a smart phone system. It uses the microphone and speaker of the smart phone
to emit sound and analyse its reflection or echo from the ear drum. The
analysis was also conducted among parents of pediatric patients and has proved
the efficacy of the smart phone in detecting middle ear fluid.
The smart phone app was tested in 98 pediatric patients and it was as found that it performed better than acoustic reflectometry systems in detecting middle ear fluid.
Middle ear fluid can be a symptom of infection in the ear and it may cause pediatric ear diseases such as acute otitis media and otitis media with effusion. Commercial acoustic reflectometry achieved an area under the curve (AUC) of 0.898. Hence, this can be used as a cost-effective and easy way.
