An apparatus for monitoring one or more patient digestive processes, the apparatus comprising: (a) a computer processor configured to be coupled to an acoustic sensor ; and (b) a non-transitory computer-readable memory storing instructions executable by the computer processor ; (c) one or more digestive acoustic sensor modules configured to be coupled to a patient's abdomen; (d) an acoustic sensor disposed within each said sensor module, said acoustic sensor configured for registering sounds associated with digestive processes of the patient; and (e) a vibration actuator disposed within each said sensor module, said vibration actuator configured for communicating a vibratory signal to the one or more sensor modules; (f) wherein said instructions, when executed by the computer processor , perform steps comprising: (i) registering digestive motility events received from said acoustic sensor when an acoustic signal from said acoustic sensor matches one or more predetermined digestive motility acoustic patterns; (ii) classifying one or more motility events based on said registered digestive motility events while rejecting noise induced signals or physiological phenomena other than motility events; (iii) determining proper positioning of the one or more sensor modules on the patient by activating said vibration actuator in at least one of said sensor modules; and (iv) registering acoustic signals generated by said vibration actuator on a second of said sensor modules.
