Abstract: A fetal phonocardiogram system featuring an array of acoustic sensors designed to be temporarily affixed to a pregnant patient to convert the vibrations associated with a fetal heartbeat and/or fetal movement into a signal. The signal can be amplified and transferred to a processing element for filtering non-fetal sounds in order to resolve the fetal heartbeat. The filtered signal can be used in conjunction with an array of multiple acoustic sensors to locate a fetal position relative to the array.

Abstract: Methods for monitoring a fetus employ a mobile computing device. A method of monitoring a fetus includes generating a first preprocessed acoustic signal via amplification of a first acoustic signal. The first preprocessed acoustic signal is processed by a mobile computing device to extract one or more of a fetal heart sound, a fetal heartbeat rate, or a fetal heartbeat acoustic intensity.
