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.

Unique Design
Because of the unique design of its diaphragm and sensor, the Model 3000 can be used comfortably on all body types and sizes. The versatile chestpiece can accommodate infant, pediatric and adult patients, and it is ergonomically designed for easy hand manipulation and patient comfort.
