what are the pieces of the stethoscope
Headset: The headset is the metal part of the stethoscope onto which the tubing is fitted. The headset is made up of the two eartubes, tension springs and the eartips. Chest Piece: The chest piece is the part of the stethoscope that is placed on the location where the user wants to hear sound. Most cardiology stethoscopes contain a tunable diaphragm on each side of the chest piece.
The eartubes are the metal/steel parts of the stethoscope that connect to the eartips and the synthetic/PVC tubing, which connects to the stem of the chest-piece. The eartubes are designed to to isolate and transfer sound to the users ears with minimum quality loss.
