3M Littmann 3000 Electronic Stethoscope

3M Littmann Electronic Stethoscope Model 3000 with Ambient Noise Reduction 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.

But thanks to a proprietary technological advancement known as Ambient Noise Reduction (ANR), the Littmann Electronic Stethoscope Model 3000 reduces distracting room noise by an average of 75% (-12dB) without eliminating critical body sounds. 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.
