FINDING CLARITY AMID CACOPHONY.
Until now, the advantages of amplification in an electronic stethoscope have been negated by the sensitivity of electronic stethoscopes to distracting sounds from ambient room noise and friction on the surface of the patient’s body.

But thanks to a patented technological advancement known as Ambient Noise Reduction (ANR), the

3M Littmann Electronic Stethoscope Model 3000 allows you to tune out the room when you turn up the volume.

This new technology reduces distracting room noise by an average of 75% (-12 dB) over the bell and diaphragm operating range. Combine that with amplification up to 18 times greater than the best acoustic (non-electronic) stethoscope and you have an instrument that is uniquely equipped to help you pick up difficult-to-hear heart, lung and other body sounds. Even when the world around you is filled with distracting noise.

WHAT CLINICIANS HAVE SAID.
In a test sample, 82% of cardiologists indicated it was easier to detect/hear an aortic regurgitation murmur (Grade 1 or 2) with the Model 3000 than with an acoustic (non-electronic) cardiology-type stethoscope. 90% of clinicians indicated it was easier to detect/hear abnormal lung sounds with the Model 3000 than with an acoustic (nonelectronic) cardiology-type stethoscope.

HOW AMBIENT NOISE REDUCTION (ANR) WORKS.
Ambient noise isn’t just in the air; it also travels through the patient’s body. The key to reducing ambient noise is to address both pathways. And ANR does just that without filtering away important sounds. Noise from the room enters the stethoscope through a thin gap in the chestpiece and, once inside, meets noise that enters through the body. The two cancel each other out, leaving the heart, lung and other body sounds you want to hear.

ANR technology acoustically cancels out an average of 75% of distracting room noise. This acoustic canceling effect is different to electronic filtering, which may also filter out some portions of body sounds.
