A stethoscope is a medical tool that listens for interior body noises using sound waves. Two components make up a stethoscope: A diaphragm (or bell), which converts sound from the chest cavity into air, and tubing, which returns the air to the earpiece, are the two components involved. The bell, which is connected to the flexible tube known as the tubing, is connected to the diaphragm. The earpiece, via which the patient hears the sound, is connected to the tube.
The Digital Stethoscope is a modern version of the traditional stethoscope. Instead of a bell, this device detects sounds using a microphone. These noises are transformed by the microphone into electrical signals that your computer or smartphone can understand.
