A wireless auscultation system using a multi-function digital stethoscope includes a digital stethoscope(10) and a receiving device(20). The digital stethoscope includes an auscultation input part, a control part, a bluetooth transmitting part, a key input part, and a storing part. The auscultation input part transforms an auscultation sound collected from a sound collecting part(14) into a digital type auscultation data. The control part stores the digital auscultation sound signal, outputs the signal to LCD(12) and outputs the auscultation data to the bluetooth transmitting part. The bluetooth transmitting part wirelessly transmits the data to the receiving device. The key input part generates a key signal and inputs the signal into the control part. The storing part stores the auscultation data inputted from the control part. The receiving device includes a bluetooth receiving part, a digital filter, a feedback filter, a wireless receiving part, a receiver control part. The bluetooth receiving part receives the auscultation data through a bluetooth type. The digital filter filters the auscultation data received in the bluetooth receiving part. The feedback filter removes a feedback signal. The wireless receiving part includes a main amplifying part, a digital sub amplifying part. The receiver control part supplies power provided from a power part to the wireless receiving part so as to operate the receiving device.
