ABSTRACT:
A method and apparatus for characterizing gastrointestinal sounds includes a microphone array to be positioned on a body for producing gastrointestinal sound signals. The signals are digitized and their spectra and duration is determined by a processor. A characterization as to the state of the gastrointestinal tract is made on the basis of the spectra and duration of the sound or event.
