Stethoscope uses the principle of multiple reflections of sound.
The structure of a typical stethoscope consists of a round-shaped resonator or chest piece and a long tube. The tubes are connected to the ears while the resonator is placed on the chest to transmit it. These devices are used to monitor acoustic sound variation and also to check the scientific vacuum chambers.
COMPONENTS OF A TYPICAL STETHOSCOPE
- A round-shaped resonator or chest piece: The round-shaped resonator is made up of a bell and diaphragm.
- And a pair of head-set
Inside the tube, multiple reflections tend to occur due to wave collision within the wall of the tube. And this continues in succession until it reaches the ear tips at the other ends of the device before being picked by the listener’s eardrum.
