The stethoscope is arguably one of the most iconic and fundamental diagnostic tools in medicine. From the earliest days of listening to internal body sounds, it has been an indispensable partner for healthcare professionals worldwide. This simple yet powerful instrument allows us to auscultate - listen to the internal sounds of the body. Listening to the body’s internal sounds can offer critical insights into the health of the heart, lungs, bowels, and blood flow. Over centuries, the stethoscope has evolved from a basic wooden tube to sophisticated electronic devices engineered to improve patient care and diagnostic accuracy.
