Hear it. State-of-the-art sound sensor. Proprietary Ambient Noise Reduction (ANR) technology reduces on average 85% of unwanted background noise. Amplification capability when sounds are soft. Clinical evidence shows it’s easier to detect difficult-to-hear heart sounds like S3 gallops, aortic regurgitation murmurs, as well as abnormal lung sounds It all adds up to an exceptional listening experience—no matter what the environment—compared to acoustic scopes. |

Confirm it. Use available Zargis® Cardioscan™ software to help you detect and classify suspected heart murmurs while with your patient.
Or visualize heart and lung sounds using Zargis® StethAssist™ software, included free with every 3M™ Littmann® Electronic Stethoscope Model 3200. Two great tools that can enhance the auscultation process and help you hone your skills. | ||||||
Sound Quality So Exceptional
You might never go back to your old stethoscope.
The 3M™ Littmann® Electronic Stethoscope Model 3200’s exceptional sound capabilities deliver an exceptional auscultation experience. Clinical evidence shows that it’s easier to detect
difficult-to-hear heart sounds, like S3 gallops, aortic regurgitation murmurs, and abnormal lung sounds. Here’s why:
Proprietary Ambient Noise Reduction Technology
It cancels out, on average, 85% of ambient background noise that can interfere with the auscultation experience, without eliminating critical body sounds. So you’re much less likely to miss the sounds you need to hear in noisy work environments. A full 13% better than previous models.
Acoustic Seal Eartips and Tubing
Not only do our patented 3M™ Littmann® Snap Tight Soft-Sealing Eartips provide a comfortable fit, they also create an excellent acoustic seal, as does our tubing. It means a tighter seal from ambient noise entering through tubing and eartip connections.
State-of-the-Art Sound Sensor
Built to stringent specifications, it provides a life-like 3M™ Littmann® sound experience similar to a high-end cardiology stethoscope. Positioned at the base of the tubing, the sensor brings the sound more naturally to your ears.
Frictional Noise Reduction Technology
A number of changes in the chestpiece help reduce handling noises compared to earlier electronic stethoscopes. It’s less distracting. So it helps you focus more on what you need to hear.
Up to 24X Sound Amplification
Extra listening power for those times when you need it; may be helpful when a heart, lung or body sound is especially faint; when a patient is obese; or when a patient’s clothing restricts your listening experience.
The User Interface You’ve Been Waiting For.
Incredibly simple. Non-disruptive to your auscultation workflow.

Auscultating Patients of Different SizesThe 3M™ Littmann® Electronic Stethoscope Model 3200 has a flat diaphragm for placement stability, but all sound pick-up happens at the center. So it’s sized right for infants or adults. And the 24X amplification may be helpful when auscultating through the body of obese patients. |

Clinical Evidence
Studies comparing non-electronic, cardiology-type stethoscopes and the
3M™ Littmann® Electronic Stethoscope 3000 Series had these findings:
With the Littmann® Model 3000 Series Stethoscope...83% of cardiologists indicated it was easier to detect/hear an S3 gallop 3
82% of cardiologists indicated it was easier to detect/hear an aortic regurgitation murmur (Grade 1 or 2) 4
90% of critical care nurses indicated it was easier to detect/hear abnormal lung sounds 5 When using a non-electronic, cardiology-type stethoscope vs. the Littmann®
Model 3000 Series Stethoscope...
Cardiologists missed an S3 gallop 40% MORE OFTEN 3
Cardiologists missed a Grade 2 aortic regurgitation murmur 5 TIMES MORE OFTEN 4
Critical care nurses misidentified whether a sound was normal or abnormal TWO TIMES MORE OFTEN 5
Real Life Observations Why so many clinicians love the 3M™ Littmann® Electronic Stethoscope Model 3000 Series sound experience.

1 Based on findings from interviews, conducted by 3M in collaboration with Zargis Medical, with interested cardiologists at the AmericanCollege of Cardiology (ACC) 57th Annual Scientific Session (March 29, 2008–April 1, 2008, Chicago, Illinois). N = 39.
2 Clinical study conducted in 2005 by Zargis Medical in collaboration with The Johns Hopkins University School of Medicine. The study measured
the accuracy of a group of primary care physicians in evaluating a set of 100 recorded heart sounds. The heart sounds were independently
evaluated by each physician both with and without access to Cardioscan’s reported findings. Clin Cardiol. 2008 Feb;31(2):79-83. The impact
of computer-assisted auscultation on physician referrals of asymptomatic patients with heart murmurs. Watrous RL, Thompson WR, Ackerman SJ.
