The stethoscope is a medical device that is used to perform auscultation and clinical procedure. It consists of listening to the internal sounds of the ribcage and abdomen in search of sounds that may indicate some pathology in the organs of the trunk. Here, the question is which is the best mechanics stethoscope?
The stethoscope is one of the most used tools in general medicine. It is traditionally considered an icon of the medical profession. At present, the development of other technologies, especially the advancement of ultrasonography, is displacing the use of the stethoscope, although it is likely not to be totally relegated for a long time.
It is usually a hollow, flexible tube that forks and its ends are placed in the ears of the doctor. The end that does not separate has a bell-shaped piece that rests on the chest of the one being examined, piece with the ability to magnify the sounds and thus allow the doctor to hear better. This type of stethoscopes is called mechanic and acoustic or traditional.
There are differ types from mechanics stethoscopes. Although none comes close even to the quality and effectiveness of the traditional, electronic stethoscope has begun to be produced and used by most. Below, you can find a comparison between best mechanics stethoscope and electronic stethoscope.
Best Mechanics Stethoscope
What is mechanic stethoscope?
Mechanic stethoscopes were invented over two centuries ago. They are usually used by doctors and nurses to diagnose health problems. They have simple, mechanical construction. A chest piece picks up the sounds from the body of an auscultated patient, and a pair of hollow tubes transmits them to the ears of a physician.
The construction and parameters of the individual parts of a stethoscope are supposed to have influence on the characteristics of the transmitted sound—its level and amplification or damping of various frequency components. However, the results of some recently published investigations show that this relation is non-trivial, and that the current state of art in the field is far from fully understanding. Especially, the role of the diaphragm of a chest piece in filtering low-frequency signal components, as described in the literature, is questioned in the light of the new findings.
What is electronic stethoscope?
Electronic stethoscopes amplify sounds electronically and significantly improve the low acoustic levels of traditional stethoscopes. There are many types of electronic stethoscopes, but most are limited to the middle frequencies and attenuate the highest and lowest frequencies.
Although they have used microphones, current electronic stethoscopes often use piezoelectric crystals to reduce the effect of ambient sound that was very pronounced in devices with microphones. Electronic stethoscopes have the advantage that they can be wireless and more convenient to use. They can also be coupled to software that analyzes sounds, as well as being recorded for further study.
What are differences between best electronic and best mechanic stethoscope?
We have learned what mechanic stethoscope is and what electronic stethoscope is above. Now, let’s talk about differences between electronic and mechanic stethoscopes. After the end of this article, you will learn all about these two types of stethoscope.
The electronic stethoscopes are based on completely different operating principles. Their chestpiece is a contact microphone, which converts the vibrations of an underlying skin into an electric signal. Various models of electronic stethoscopes use different types of transducers, with different acoustic characteristics. The electronic signal is amplified, filtered, and fed to a speaker or headphones.
One of the priorities of mechanic stethoscopes is their design. However, they are not ideal because they weaken the transmission of sound in proportion to frequency, their frequency responses show maximum and minimum at very specific frequencies due to Tubular resonance effects, and differences in transmission properties are observed between different models.
Because the intensity of heart sounds and murmurs is usually weak in some sounds below the hearing threshold, amplifying the acoustic signal in electronic stethoscopes with a more uniform frequency response is introduced to solve the basic limitations of mechanic stethoscopes.
However, these advantages seem to outweigh the electronic stethoscope’s sensitivity to manipulative artifacts and electronic and environmental noise. They also do not take into account the sensitivity of the human ear, which varies significantly as a function of frequency. As a result, although several sophisticated designs for the construction of electronic stethoscopes have been patented in the last 20 years, the mechanic stethoscope remains the most widely used today.
