Electronic Stethoscope – What To Look For

electronic stethoscope

Med-students for decades have used traditional stethoscopes to run diagnostics. However very few innovations have been made in the field of stethoscope technology up until the last 10 years. Electronic stethoscope have begun to come on the market and their presence in hospitals and ambulances are on the rise!

Electronic stethoscopes are still in their infancy. However several design changes and research has led to the ones on the market today. The big benefit they bring is severe amplification of sounds. In fact, electronic stethoscopes may very well be the best solution for doing auscultation in a room filled with white noise of fans, electronic instruments, and computers.

It is advised that if you are a med- or nursing-student that you get familiar with the “standard technology”. Standard stethoscopes are after all a lot more common than electronic ones. You need to be able to use any stethoscope to perform diagnostic procedures.

Some swear by a Littmann Electronic Stethoscope, others are not sure where to turn. To know what the best stethoscope is largely depends on your field of medicine and your area of expertise.


Let’s check out a few key things about buying an electronic stethoscope, and have a look at some of the best ones on the market.


What to Look for When Buying an Electronic Stethoscope:


Popular stethoscopes use complex transducers. These allow medical professionals the ability to hear heart murmurs, lung sounds etc. in great detail. Transducers turn analog sound waves to a digital sound pattern. These can then be amplified and modified for a variety of uses. This gives the user something you don’t get with a traditional stethoscope.

Ambient noise handling and reduction

Anyone who has ever been to a concert knows how a feedback loop sounds like. The high-pitch screech coming out of the speakers as a result of an amplified sound being amplified again. Such is the case also with an electronic stethoscope. Under certain circumstances loud ambient noises can be amplified by the stethoscope.

Luckily the engineers who have developed this technology have thought about this and implemented procedures to prevent this. They have come up with digital stethoscopes capable of eliminating unwanted sounds in an auscultatory process.

Communication protocol and Software

The big benefit of electronic stethoscopes over traditional ones is the fact that the analog sound waves are turned digital. Anything digital means it can be stored, modified and transmitted. As a result it is now possible to keep a record of your patient’s vital signs which can prove useful for future diagnostics.

At the same time if your patient would at some point change physicians it is easy to transfer their medical history with the click of a button.


In the early days of electronic stethoscopes they would fail prematurely due to battery failure. However current market leaders today guarantee a longer battery life. Even when used more than 25 times a day, 5 days a week with a single AAA battery.

Ease of use

User-friendly electronic stethoscopes should have easy to use controls and dedicated buttons to adjust volume up/down, power on/off and change mode between bell/diaphragm right on the head
