The term 'stethoscopes' detections' can be summarized as the sound of a heartbeat, which is detected by a stethoscope. A stethoscope is a medical instrument used to listen to the internal sounds of a person's body, such as the heartbeat and breathing. It is composed of a small disc-shaped resonator that is placed against the chest, and two tubes connected to earpieces. The sound waves created by the heart are amplified by the resonator and then transmitted through the tubes to the earpieces. By listening to these sounds, a doctor can diagnose various conditions and diseases.
