How much does a stethoscope magnify sound?
How much does a stethoscope magnify sound?
The modern stethoscopes will help to magnify sound up to twenty percent. The sound amplification of the electronic stethoscopes is impressive. It helps to increase the sound artifacts. As a result, the doctors can listen to sharp sounds of heart and lungs comparing to the acoustic stethoscopes.
Do stethoscopes use sound waves?
When a doctor or nurse places a stethoscope diaphragm on a patient’s chest, sound waves traveling through the patient’s body cause the flat surface of the diaphragm to vibrate. In this way, each wave, in succession, reaches the eartips, or rubber nubs on the ends of the device, and finally the listener’s eardrums.
How expensive is a stethoscope?

How does a stethoscope listen to the sound?
As a result, the diaphragm vibrates according to the sound wave. The flat surface of the diaphragm is connected with a tube that is directed to the ear tip of the stethoscope. Doctors put the ear tips into the ears and listen to the sound.
How are electronic stethoscopes used in the medical field?
The sound amplification of the electronic stethoscopes is impressive. It helps to increase the sound artifacts. As a result, the doctors can listen to sharp sounds of heart and lungs comparing to the acoustic stethoscopes. The electronic stethoscopes are also called digital stethoscope.
How is a stethoscope connected to the diaphragm?
When the stethoscope it put on the body, the sound waves of human body creates vibration in the diaphragm. As a result, the diaphragm vibrates according to the sound wave. The flat surface of the diaphragm is connected with a tube that is directed to the ear tip of the stethoscope.
Which is the best type of amplified stethoscope?
In order to get good amplified sound, electrically amplified stethoscopes are the best choice. The traditional stethoscopes are available in many sizes, types, weights, and designs. However, the traditional stethoscopes may not give accurate sound. The modern stethoscopes will help to magnify sound up to twenty percent.
