Ambient Noise Reduction Technology


Don't miss the sounds you need to hear


With proprietary Ambient Noise Reduction Technology, you’ll more easily detect critical sounds – such as S3 gallops, aortic regurgitation murmurs, abnormal lung sounds and all the sounds you need to hear – even in noisy work environments. You can also amplify the sound level up to 24 times, for sounds that are especially faint.

Ambient Noise Reduction Technology cancels 85% (on average) of ambient background noise.

Volume control lets you amplify critical body sounds up to 24 times.

Available with the Littmann® Model 3100 and Littmann® Model 3200 stethoscopes, Ambient Noise Reduction Technology works with the reduced friction and sound amplification features to deliver an exceptional auscultation experience.

For an additional level of performance, the Model 3200 allows you to record sounds, as well as transmit and share sounds with colleagues using Bluetooth® technology.
