👉 A stethoscope is a medical device used for listening to sound waves and detecting sounds. It consists of two large, thin metal tubes called "stapes," which are attached to the end of a long tube, called the tympanum. The tympanum is connected to the ear by a small hole in the head. The stethoscope uses an electronic microphone system that converts sound waves into electrical signals. These signals can be then sent to a computer or other device for analysis and interpretation
