A stethoscope is a medical device used for listening to internal sounds in the body, such as the heartbeat, lungs, and intestines. It consists of a small disc-shaped resonator that is placed against the patient's body and two tubes connected to earpieces for listening. To use a stethoscope, place the disc-shaped resonator on the area of the body you want to listen to, and then listen through the earpieces. It's important to use a stethoscope in a quiet environment to accurately hear the internal sounds. Stethoscopes are commonly used by healthcare professionals such as doctors, nurses, and paramedics to assess a patient's health and diagnose medical conditions.
