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.
