Abstract
Audio signals, collected with equipment commonly available to individuals (e.g., a mobile device), can be used to analyze a patient's breathing. An audio signal associated with the patient's breathing for a time period can be detected with the mobile device and used to approximate the patient's respiratory flow for the time period. For example, the audio signal can be analyzed by determining a representation of an audio frequency of the audio signal, splitting the audio frequency of the audio signal into distinct time steps, determining points comprising a weighted mean frequency at each time step, applying a frequency-to-flow rate linear transformation at each time step to approximate the respiratory flow versus time, and plotting a graphical representation of the respiratory flow versus time. The respiratory flow for the time period can be tagged with a factor related to the patient and saved in a database for future analysis.
