Recent study reported that the prevalence of Irritable Bowel Syndrome (IBS) is 13.1% among Japanese population. Altered motility patterns may be associated with diagnostic features of IBS. In recent years, bowel motility was conveniently evaluated by the analysis of bowel sounds recorded using the stethoscopes. However this sound recording requires contact to the body. We know from our previous experience that we can hear borborygmi without the aid of a stethoscope. In this study, we propose a new method to evaluate bowel motility based on the acoustic analysis of borborygmi acquired from a non-contact microphone. Through the experiments, we show that bowel motility can be evaluated via the analysis of borborygmi, similar to a stethoscope-based technique. Furthermore, we show that the proposed method may have the potential to characterize IBS. From these results, we conclude that the proposed method may become a simple and useful tool in evaluating bowel motility.
