Hear the difference: The powerful partnership between 3M, the world’s leading manufacturer of stethoscopes, and Bang & Olufsen Medicom, the recognised specialist in intelligent medical device solutions, has created a state-of-the-art electronic stethoscope that is revolutionising auscultation technology.
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. Combine that with amplification up to 18 times greater than the best non-electronic stethoscope and there's less chance you'll miss the sounds you need to hear.
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.
