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

3M™ SOUND ANALYSIS SOFTWARE,
SO YOU CAN SEE AND SHARE HEART SOUNDS.
With the 3M™ Littmann® Electronic Stethoscope
Model 4100 and accompanying 3M™ Sound Analysis Software, what you hear can also be
what you see and share with others. This exquisite, state-of-the-art auscultation instrument comes with
proprietary software that lets you see exactly what you’re hearing on your IBM-compatible computer
or Pocket PC. This “hardware” and software combination will enhance teaching opportunities, serve as a
diagnostic aid and help you make more effective use of telemedicine.
