How Littmann Ambient Noise Reduction (ANR) technology works
Reduces background noise that can interfere with the auscultation experience now up to 85% on average. Ambient noise travels into the stethoscope both through the air and through a patient's body. The Littmann Model 3100's proprietary ANR technology uses both sources of ambient noise to cancel each other out, leaving only the unfiltered sound of the heart, lung or body sound to be heard.
Sound quality so exceptional, you might never go back to your old stethoscope.
Clinical evidence shows the 3M™ Littmann® Electronic Stethoscope Model 3100 makes it easier to detect difficult-to-hear heart sounds like S3 gallops and aortic regurgitation murmurs, as well as abnormal lung sounds. Here's why:
Ambient Noise Reduction
It cancels out, on average, 85% of ambient background noise that can interfere with the auscultation experience, without eliminating critical body sounds. So youre 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. Its 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 patients clothing restricts your listening experience.
