Diaphragm VS Bell of Stethoscope

Bell vs diaphragm stethoscope


Hi there! The importance of stethoscopes to medical practitioners cannot be over-exaggerated. It is an all-important tool to have in handy, especially in emergencies.

As a medical student who is still learning the trade, you may have had debates among your peers as to which stethoscope is best – the bell stethoscope or the diaphragm stethoscope.

As far as stethoscopes are concerned, there are many different ways of grouping them. You can have groups based on intended application, or even mechanism of sound reception and transmission.

With the above example, there are two major types of stethoscopes, these are acoustic and electronic stethoscopes.

With electronic stethoscopes, all the information is compiled on the chest piece with the use of special sensors and transducers. The main advantage they have is that there is minimal interference or loss of clarity during transmission. They also facilitate automation of things like calculating heart and breathing rates.

Acoustic stethoscopes on the other hand basically rely on traditional vibration and sound transmission through the reflection of the waves.

Sensitive membranes on the chest piece pick up and mimic vibrations from the skin and deeper tissues. These vibrations are passed on as waves via a tubing, designed to permit continuous reflection until the sound reaches the ears through the headset.

This traditional design is simple but very effective. It guarantees high quality and high clarity sound transmission with almost no alteration of the original sound waves.

Acoustic stethoscopes usually feature some version of the bell and diaphragm.

So, let’s get into it – the bell stethoscope vs diaphragm stethoscope.
