The present invention relates to a stethoscope auscultation method, adapted for an improved stethoscope so as to be used for assisting a medical diagnosis according to visceral sounds. The stethoscope auscultation method comprises the steps of: providing a stethoscope, whereas the stethoscope is composed of a stethoscope head module, a processing unit and a signal output unit, and the stethoscope head module further comprises a sensor and a visceral sound receiver enabling the sensor to issue an activation signal to the processing unit as soon as it detects that the stethoscope head module enters an auscultation mode, and thereby activating the stethoscope using the stethoscope to perform an auscultation process upon a living body as the visceral sound receiver is enabled to obtain audio signals originated from the visceral organs of the living body enabling the processing unit to shut off the stethoscope automatically when the visceral sound receiver is unable to obtain the audio signals originated from the visceral organs for environmental purposes, such as reducing power consumption of the stethoscope, prolonging lifespan of the battery used in the stethoscope.
