Littmann stethoscopes are known for their superior acoustics and are used worldwide by millions of health professionals. 3M Littmann continues to innovate and bring new tech to the market. While tunable diaphragms and Ambient Noise Reduction were great improvements, it is the new range of digital stethoscopes that are revolutionizing cardiology this century. With features like up to 40x amplification and active noise cancellation the real benefits are found in the ability to record patient sounds (on a smartphone) so they can be reviewed, compared and shared easily.
Doctor David Littmann was a renowned cardiologist and Harvard professor. He designed and patented a lighter type of stethoscope with vastly improved acoustics when compared to other versions in the market. Within a few short years of this discovery, 3M acquired Dr Littmann’s stethoscope business in 1967. 3M continues to develop new features for the Littmann stethoscope range making it the standard that other stethoscopes are all compared to.
