Listening to subtle differences in lung and heart sounds is difficult enough without having to deal with road noise, diesel engine idling or helicopter rotors on scene. The newÜ3M Littmann Electronic Stethoscope Model 3000 features ambient noise reduction (ANR) technology that cancels out an average of 75% of the distracting room noise. It also has an amplifier that increases sounds up to 18 times that of the highest-quality acoustic stethoscopes. Select the frequency response you want — either bell or diaphragm — and adjust the volume to your comfort level. One AAA battery will power the stethoscope for approximately 200 hours, and it automatically powers off after three minutes to conserve energy.
