Breath Sound Analyser for Children (KDAC)
This system provides respiratory health information based on breathing sounds recorded by using computers, mobile phones, and digital recorders.The system can detect four types of respiratory health problems for young children (age range 0.5 to 7 years): pneumonia, flu, bronchitis, and colds. The system also supports detecting general respiratory problems for all ages. Record breathing sound using your computer or mobile phone and upload the sound file to receive diagnosis results and statistics of the breathing sound.

How to record breathing sound using mobile phones
Place the microphone of your mobile phone directly under the nose or mouth, as close as possible, but not touching the baby.
The best time to record is when the baby is asleep or resting. Please DO NOT ask to “breath” to avoid forceful breathing.
After recording, playback the recorded sound to check if you can hear the breathing sound. Record the breathing sound at least for 1 minute (or 7 to 9 breaths).
The best method is to use a handsfree microphone, which usually comes with mobile phones. You can upload the sound file using this application: KOPO DAC.
