Bowel sounds refer to the intermittent gurgling sound produced by the flow of gases and liquids in the intestinal tract during peristalsis. Under normal circumstances, intestinal sounds 4 to 5 times per minute, its frequency, sound and tone varies greatly, frequent and obvious after meals. If intestinal peristalsis is enhanced, the intestinal sound reaches more than 10 times per minute, and loud, high-pitched, or even a tinkling sound or metallic sound, known as intestinal hyperphonia, mostly seen in patients with mechanical intestinal obstruction.

1, intestinal hyperacusis can be physiologic, can also appear in the pathological state. Physiological increase in intestinal peristalsis is common in hunger, or when the abdomen is stimulated by cold, heat and other adverse factors, at this time the gibberish is usually episodic, or very short duration.

2, pathological intestinal chirping hyper situation is seen in gastrointestinal inflammation, such as dysentery, acute gastroenteritis, intestinal obstruction, or cold diarrhea, etc., intestinal peristalsis is hyperactive, persistent, and can cause intestinal colic in severe cases.
