摘要：
A bowel sound analysis method and system utilizes an audio collection apparatus to continuously monitor an abdominal cavity of an examinee and collect a bowel sound signal of an intestinal tract inside the abdominal cavity, converts the bowel sound signal into a digital signal, then removes noise from the digital signal by using higher-order statistics (HOS) and captures a high-complexity feature from the digital signal by using fractal dimension algorithm, and subsequently defines the high-complexity feature as an intestinal motility signal. Therefore, according to the intestinal motility signal, a time point when intestinal motility occurs in the intestinal tract inside the abdominal cavity of the examinee can be learned, and bowel sound features such as the amplitude, frequency, and period of the intestinal motility signal may further be analyzed to determine a health condition of the intestinal tract.
