1. A mobile sensing system, comprising:

  • a microphone configured to capture a set of non-speech body sounds while dampening external sounds and ambient noises;

    an audio codec module receiving an analog audio signal representing the captured set of body sounds from the microphone and converting the analog audio signal to a digital signal;

    a micro-controller coupled to the audio codec module to filter out non-body sounds from the digital signal and preprocess the filtered digital signal into frame data; and

    an audio processor receiving the frame data from the micro-controller, configured to recognize the captured set of body sounds by performing body sound classification based on a set of discriminative acoustic features identified in the frame data.
