Question

What is the working of Stethoscope?​

Answer 1

Explanation:

The disc and the tube of the stethoscope amplify small sounds such as the sound of a patient's lungs, heart and other sounds inside the body, making them sound louder. The amplified sounds travel up the stethoscope's tube to the earpieces that the doctor listens through.

Answer 2

A stethoscope has a chestpiece, diaphragm and/or bell, stem, tubing, headset, eartubes, and eartips.If the diaphragm is placed on the patient, body sounds vibrate the diaphragm, creating acoustic pressure waves which travel up the tubing to the listener's ears. If the bell is placed on the patient, the vibrations of the skin directly produce acoustic pressure waves traveling up to the listener's ears.
