3M Introduces Littmann Electronic Stethoscope Model 3000 with Breakthrough Ambient Noise Reduction (ANR) Technology; Designed to Pick Up Difficult-To-Hear Heart and Lung Sounds While Offering Superior Acoustic Sensitivity
3M created the Littmann Electronic Stethoscope Model 3000 featuring amplification and proprietary ambient noise reduction (ANR) technology. The new Littmann Model 3000 has been proven to reduce ambient noise by an average of 75 percent without filtering out critical body sounds and offers amplification up to 18 times greater than the best acoustic stethoscope. This breakthrough technology represents a key milestone in the area of acoustic sensitivity that can be critical to proper clinical diagnosis and quality auscultation.
In recent controlled experiments, clinicians using the Littmann Model 3000 have picked up difficult-to-hear heart and lung sounds, while missing or misidentifying those same sounds with an acoustic (non-electronic) cardiology-grade
