Background technique

A stethoscope is a medical instrument used to listen to sounds inside the human or animal body. At present, the stethoscope actually used by hospital doctors is a non-digital device. Its principle is the vibration conduction between substances, and the human veins, arteries, heart (20-600Hz), lung (100-1500Hz), intestine (20-1500Hz) The internal sound signal is transmitted to the doctor's eardrum, and the doctor should judge whether it is abnormal and calculate the heart rate based on his own experience. However, the sound transmitted in this way passes through the human ear, and can only hear the range that the human ear can hear, but cannot truly express all the signals in the range of 20-2000 Hz in the veins, arteries, heart, lungs, and intestines of the human body.
