摘要
本文介绍了对肠鸣音的采集与分析，由高灵敏度肠鸣音检测电路和微机可对肠鸣音进行灵敏、快速、方便的采集和时、频域定量分析，并精确、完整地显示、记录、存储分析结果。本文对几种肠鸣音的分析方法进行了讨论，并通过临床实验对肠鸣音的特点做出了总结。
This paper introduces the hardware and the software for the gath-ering and analyzing of the intestianal sounds.A system of a high sensi-tyivity acquireing circuit and a microcomputer. It can sensitively andrapidly acquire a set of parameters including time domain and freque-ncy domain. It also accurately. This paper also discusses the methodsof frequency spectrum, and summarizes the chatacteristics of intestinalsounds from clinic experiments.
