Abstract :
The general framework of this communication is phonoenterography. The ultimate goal is the development of a clinical diagnostic tool based on multi-channel abdominal sound monitoring. This paper concerns essentially the source localization problem in phonoenterography. After studying different sound localization methods, all based on abdominal surface auscultation, we propose and justify our method and we present the first results we have obtained on real multi-channel recordings.
