A stethoscope is an acoustic medical device for auscultation, or listening to internal sounds of the body. It is often used to listen to heart sounds and breath sounds. It is also used to listen to intestines and blood flow in arteries and veins.

The stethoscope was invented in France in 1816 by René Laennec at the Necker-Enfants Malades Hospital. It consisted of a wooden tube and was monaural. Laennec invented the stethoscope because he was uncomfortable placing his ear on women’s chests to hear heart sounds. The name stethoscope comes from the Greek words (stéphanos) and (skopé), meaning “chest” and “to examine”, respectively.

The first flexible stethoscope was invented in 1851 by George Cammann, who was a physician in New York City. His design, which is similar to modern stethoscopes, had a piece of rubber tubing attached to a metal binaural. In 1852, Cammann sold the rights to his stethoscope to Samuel S. White of Philadelphia. White improved the design of the stethoscope and introduced the first stethoscope with a rubber tubing in 1853. In 1854, White sold the rights to his stethoscope to George P. Cammann, who then sold the rights to Alexander J. Cardy in 1855. Cardy made the first binaural stethoscope with ivory earpieces. In 1876, Cardy sold his company to George S. Parr. Parr then began to mass-produce stethoscopes under the name Cardiophone. In 1877, Parr moved the Cardiophone company to Rochester, New York.

The first electric stethoscope was invented in 1925 by Harold H. Hopkins. Hopkins was a professor of physiology at the Royal Infirmary in Edinburgh, Scotland. He invented the stethoscope as a way to amplify heart sounds. His design was similar to a modern stethoscope, with a diaphragm and a bell. The first battery-powered, portable stethoscope was invented in 1955 by David L. Levy. Levy was a physician in New York City. His design was similar to a modern stethoscope, with a diaphragm and a bell. The first digital stethoscope was invented in 2000 by Phillip E. Green. Green was a professor of electrical engineering at the University of Washington. His design was similar to a modern stethoscope, with a diaphragm and a bell. The first wireless stethoscope was invented in 2006 by Jayant S. Patel. Patel was a professor of electrical engineering at the University of Illinois. His design was similar to a modern stethoscope, with a diaphragm and a bell. The first 3D-printed stethoscope was invented in 2014 by Tarek Loubani. Loubani is a doctor and an engineer. His design was similar to a modern stethoscope, with a diaphragm and a bell.
