Application to check your lungs

    A smartphone app able to analyze the air volume of a person's lungs from audio recordings could make it easier for people to track their lung health.
    The application is able to analyze lip reverberation in order to monitor pulmonary diseases like chronic obstructive pulmonary disease, asthma and cystic fibrosis. By creating a model of a person's trachea and vocal tract, it is possible to mimic the tubes of a spirometer while using the phone to analyze sound wave frequencies as they resonate through the natural pipes of the human body. The software is able to translate audio into air volume with an accuracy within 5.1 percent of a conventional spirometer.
