Abstract :
This work shows the development of a tool useful in the characterization of intestinal noises (INN), this with the aim to identify certain pathologies of the digestive system in the nearby future. The proposed system has 8 audio transducers (7 for reception from INN and 1 for environmental noises (ENN). Signals are detected through a circuit that conditions them and then they are digitalized, filtered (eliminating ENN), compacted and finally stored for its further analysis.
