Sound
A stomach rumble, also known as a bowel sound, peristaltic sound, abdominal sound, bubble gut or borborygmus (pronounced /ˌbɔːrbəˈrɪɡməs/; plural borborygmi), is a rumbling, growling or gurgling noise produced by movement of the contents of the gastro-intestinal tract as they are propelled through the small intestine ...
Rates
Peristaltic waves follow each other continuously at a fixed rhythm and rate. In man, for example, the peristaltic rhythm of the stomach is 3 waves/min, with each wave moving at the rate of 0.5 cm/sec; intestinal peristalsis occurs at the rate of 6 waves/min.
