Hear the difference:
The 3M™ Littmann® Electronic Stethoscope Model 3000 allows you to tune out the room when you turn up the volume. 3M´s new Ambient Noise Reduction technology reduces distracting room noise by an average of 75% (- 12 dB) over the bell and diaphragm operating range. This stethoscope 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.
How Ambient Noise Reduction (ANR) works:
The proprietary Ambient Noise Reduction technology internal to the chestpiece, acoustically cancels out an average of 75% of distracting room noise, greatly enhancing overall utility. This acoustic effect is different from electronic filtering, which may also filter out some portions of body sounds clinicians need to hear.
