How Ambient Noise Reduction works The proprietary Ambient Noise Reduction (ANR) technology, internal to the chestpiece, acoustically cancels out an average of 75% of distracting room noise, greatly enhancing overall utility. This acoustic canceling effect is different from electronic filtering, which may also filter out some portions of body sounds clinicians need to hear.
