Hear the difference.An internal 3M test showed that heart sounds heard through the adult diaphragm of a 3M™ Littmann® Stethoscope were more than four times louder (20 dB) than the same sounds heard through a different brand of stethoscope*.
That's like the difference between whispering and talking. It could be the critical difference between hearing something significant in a patient, or not hearing it at all.

See the difference.Kinks or bends indicate stiff tubing which can pull on eartips and make the stethoscope hard to use. 3M™ Littmann® Stethoscope tubing hangs straight; it flexes easily as you examine a patient
3M™ Littmann® Stethoscope eartubes are symmetrical for ideal eartip seal and comfort. The headset should be adjustable for individual fit and comfort. The headset tension of all 3M™ Littmann® Stethoscopes is easily adjusted by gently squeezing the eartubes together to increase tension, or pulling them apart to decrease tension.
-
Feel the difference.Run your fingers over the 3M™ Littmann® Stethoscope snap tight eartips. They're smooth to seal comfortably inside your ears without irritation. Now try to pull one off the eartube. The eartips really do snap tight for maximum acoustic performance and safety. Finally, feel the weight. 3M™ Littmann® Stethoscopes are designed to feel light and comfortable when draped around your neck or carried in a pocket.

Eartips are the parts that fit into your ear. They should fit snugly, sealing out ambient noise and helping you to focus on auscultation. All 3M™ Littmann® Stethoscopes are fitted with snap-tight, soft-sealing eartips.

The headset is made up of two eartubes, the yoke and the eartips. 3M™ Littmann® Stethoscope headsets can be adjusted to ensure a proper fit into your ear canals by squeezing or pulling apart the eartubes.

Sound travels from the chestpiece through flexible tubing and then through the metal eartubes. 3M™ Littmann® Stethoscope eartubes are made of an aerospace aluminum alloy that provides both strength and lighter weight.

The chestpiece is placed on the patient to capture sounds. Some 3M™ Littmann® Stethoscope models have a one-sided chestpiece with a tunable diaphragm. Others have a two-sided chestpiece with a diaphragm on one side and a bell on the other.

3M™ Littmann® Cardiology Stethoscopes have dual-lumen tubing: two sound paths inside one outer tube which helps eliminate the rubbing noise generated by traditional twin-tubed stethoscopes.

The stem connects the stethoscope tubing to the chestpiece. On 3M™ Littmann® Stethoscopes with two-sided chestpieces, the stem is used to index, or open, the side of the chestpiece that you wish to use.

A tunable diaphragm is a 3M invention that lets you easily switch between hearing high- and low-frequency sounds simply by adjusting the pressure on the chestpiece.

Warranties and repairs
Most parts of a 3M™ Littmann® Stethoscope can be replaced while it is still under warranty. After the warranty has expired we offer affordable repairs that include replacing the tubing eartubes, diaphragm, rim, nonchill sleeves and eartips. It is recommended that the 3M™ Littmann® Stethoscope chestpiece is replaced after ten years of use.
While we're showing a 3M™ Littmann® Cardiology III™ Stethoscope in these examples, please note that all current Littmann® Stethoscopes (with the exception of electronic models) have similar components.
Learn how to listen
Ascultation is a clinical skill worth learning. The ability to accurately identify various heart, lung, and bowel sounds can help you quickly and efficiently assess patients and monitor their condition. The following conditions and equipment will help you perform a proper auscultation:
-
• A quiet, well-lit, warm room
-
• An appropriately disrobed patient. This allows you to place the stethoscope directly on the chest or back and will eliminate distortions and frictional noise from clothing.
-
• The ability to examine the patient supine, sitting, and in left lateral recumbent positions. You may hear different sounds, especially abnormal ones, in different positions.
-
• A stethoscope with both a bell and diaphragm (or the capacity to act as a bell and diaphragm) is essential.
