Common types of stethoscopes

These stethoscopes differ from each other on the basis of their design, chest piece and diaphragm, tubing, headsets and stems. While buying the stethoscope, it is very important to consider these parts for making the right selection.
Among the mentioned types of stethoscopes, acoustic stethoscope is the best one. It is widely popular and used by most of the medical professionals. Sound waves are transmitted from diaphragm up to the earpiece with the help of several hollow tubes. In the acoustic models, there are two sides of chest piece i.e Diaphragm and bell. Diaphragm is the flat side of the stethoscope while bell is the opposite portion of diaphragm. For the delivering sound waves of high frequencies, diaphragm is responsible while the bell is responsible for identifying low frequencies.
Innovations in the design and functionality of stethoscope are attributed to the advancement in science and technology. Electronic stethoscope is the most advanced version of stethoscope still it is not much popular because many medical professionals are not aware of its functionality. It is ideally used by the medical professionals who are experienced in the medical field and have learned its usage effectively. This type of stethoscope is called as stethophone. Body sound waves are converted into electronic signals with the help of electronic transducers. These digital sound waves are then amplified to make it easy for the listeners to listen and understand the sound waves clearly. Recording stethoscope is a type of electronic stethoscope which is capable of recording the sound waves. Thus, it enables the doctors to listen unusual sound waves anytime.
