低噪声多模电子听诊器设计
Design of Low-Noise Multi-mode Electronic Stethoscope
摘要
Abstract
A low-noise multimode wireless electronic stethoscope was designed.Compared with traditional stethoscope,it can hear the bioacoustics sound with a low amplitude and save the sound into wav file and transform it to graphic signal.Featured in low-noise and high sensitivity, the electronic stethoscope can work in wireless mode in order to avoid noise caused by the friction between the PVC tube from traditional stethoscope and clothes or skin.The electronic stetho-scope is equipped with the heart sound mode and the breath sound mode,which can adj ust the fil-ter bandwidth for different input signal,and primarily process the recording sounds for oscillog-raphy.关键词
