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 10% 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.

Clinical Evidence With the Littmann® Stethoscope 3000 Series...

83% of cardiologists indicated it was easier to detect/hear an S3 gallop1

82% of cardiologists indicated it was easier to detect/hear an aortic regurgitation murmur (Grade 1 or 2)2

90% of critical care nurses indicated it was easier to detect/hear abnormal lung sounds3

When using a non-electronic, cardiology-type stethoscope vs. the Littmann® Stethoscope 3000 Series...

Cardiologists missed an S3 gallop 40% MORE OFTEN1

Cardiologists missed a Grade 2 aortic regurgitation murmur 5 TIMES MORE OFTEN2

Critical care nurses misidentified whether a sound was normal or abnormal TWO TIMES MORE OFTEN3

In Controlled Experiments 1) 191 cardiologists, the overwhelming majority of whom had not previously used the 3M™ Littmann® 3000 series, listened to pre-recorded heart sounds with and without an S3 gallop of two different magnitudes, presented in random order and in the presence of 70-75 dB ambient noise. They listened with both a Littmann® 3000 series and an acoustic (non-electronic) cardiology-type stethoscope.

2) 100 cardiologists listened to pre-recorded heart sounds with and without a Grade1 or Grade 2 aortic regurgitation murmur, presented in random order in the presence of 70 –75 dB ambient noise. They listened with both a Littmann® 3000 series and an acoustic (non-electronic) cardiology-type stethoscope.

3) 136 critical care nurses listened to, and were asked to identify, pre-recorded normal and abnormal lung sounds presented in the presence of 70-75 dB ambient noise, using a Littmann® 3000 series and an acoustic (non-electronic) cardiology-type stethoscope.
