Last Updated on February 23, 2022

We updated our selection of the best digital stethoscopes for this new year. The 3M Littman Core is now our overall winner. Offering the possibility to toggle between analog and amplification modes quickly, this model combines the best of both worlds and is the model to consider in 2024.

With more than 18 million people dying of Cardiovascular Diseases (CVDs) every year, it is critical to detect cardiac illnesses early. Heart auscultation goes far beyond checking the heart rate. It relates to detecting and interpreting heart sounds (HS). From its invention more than 200 years ago by Rene Laennec, the traditional acoustic stethoscopes have come a long way.

The heart sounds contain a mixture of different high-frequency and low-frequency sounds that can be difficult to hear and interpret. Noise-canceling technologies are especially useful in noisy environments such as Emergency Rooms. For Veterinarians, they allow reducing the sound of the chest piece on the animal’s fur.

Electronic stethoscopes will convert acoustic sound waves into electronic signals. The amplified sounds are processed using various algorithms to help practitioners detect and interpret clinical anomalies. Using Bluetooth technology, the data can also be sent to a smartphone or a tablet for further analysis or to get a second opinion.

Digital stethoscopes are more expensive than their analogic counterparts. It is somehow challenging to compare the comfort of use they offer, especially the sound quality obtained, with the ambient noise reduction technology.

They can also be beneficial for medical students. They allow hearing the patient’s sounds more clearly. For some of them, the associated app offers the possibility of recording and saving the clinical examination for later review or seeking a second opinion.

We selected three digital stethoscopes for their performance and ease of use.

With a total weight of 8.1 ounces (232 grams), the 3M Littmann CORE is lightweight and comfortable to wear and a durable piece of equipment that incorporates numerous technological breakthroughs. For example, the sounds are amplified up to 40x, and with a proprietary ambient noise reduction technology, cancels 85% of the background noises.

The Littmann electronic stethoscope is perfect for veterinarians with its frictional noise reduction technology. Easy to use and durable, it offers charges via micro-USB. One charge of the lithium-ion battery offers 8-hour life. In addition, it offers the best of both worlds, as the amplification and analog can be switched directly from the toggle.

Sounds can be recorded or transferred in real time to a computer for further analysis. Compatible with the HIPAA-compliant Eko software, the 3M Littmann Core electronic stethoscope can also be used for telemedicine or benefit from Artificial Intelligence algorithms. In January 2020, the FDA even gave clearance to EKO for an algorithm detecting heart murmurs.

The 3M Littmann Core is sturdy and can endure the rigors of a busy day. It comes with a durable metal chest piece and traditional tubing that perfectly fits into a pocket or around the neck and an extra set of earpieces.

With a two-year warranty and 30 days money-back guarantee, this model does not come cheap but is ideal for cardiologists, critical care nurses, ER doctors, general practitioners, medical students, pediatric specialists, registered nurses, and veterinarians.

Cardionics is not new to the electronic stethoscope market. Professor Abe Ravin, M.D., FACC from the University of Denver, Colorado, founded the company in 1969.

When developing the first heart sound amplifier, the goal of Pr. Ravin was to help his students differentiate between normal and abnormal cardiac and pulmonary sounds. The company remains true to these core principles more than fifty years later.

The E-Scope is lightweight and is excellent for general practitioners for heart, breath, bruit, bowel, or Korotkoff sounds. Especially well suited for people suffering from hearing loss. The level output is 120dB at 100Hz, corresponding to an amplification of approximately 30 times a standard stethoscope. Powered by just one AAA battery, the stethoscope will automatically be powered off after 1.5 to 2 minutes.

The volume control is located on the head of the stethoscope for easy increase and decrease. The sound amplification offers 64 levels for precise adjustment and restarts once switched off and on at the previous setting.

The Cardionics E-Scope II 7700 also integrates an output jack for accessories, such as headphones for a second listener, to broadcast sounds or connect to a PC for recording or telemedicine purposes. To be noted, the 7710 belt model does not come with an earpiece set. Perfect for never losing your stethoscope again.

This reliable and durable stethoscope comes with an accessory pack, including a pediatric diaphragm, plastic adult diaphragm, pediatric and infant bells, and several ear tips. The E-Scope is an excellent choice with a one-year warranty, even though its price is in the high-end range.
