A labeled diagram to show the multiple reflections of sound in a part of the stethoscope tube:

A stethoscope is used by doctors to hear our heartbeats. It consists mainly of three parts: 2 earpieces, 1 chest piece, and a rubber tube to connect the chest piece to earpieces.

When the doctor puts the chest piece on the patients' chest and wears earpieces into his ear, then the sound of the heartbeats of the patient reaches to rubber tube through the chest piece. And then this sound of heartbeats reaches to earpieces by multiple reflections of sound through the inner wall of the stethoscope tube. And finally, the doctor listens to the patient's heartbeats.
