The stethoscope is an acoustic medical device, utilized to auscultate internal body sounds of animals or humans through active listening. It usually has a tiny disc-shaped resonator that rests on the skin, accompanied by one or two tubes linked directly to earpieces. With this device, users can hear heartbeats, lung and intestine sounds, as well as blood circulation in arteries and veins. Together with a manual sphygmomanometer, it's often used when taking accurate blood pressure readings. Mechanic stethoscopes, on the other hand, feature rod-shaped chestpieces that enable technicians to detect internal machinery noises - for instance, listening to worn ball bearings producing unwanted vibrations. Automotive engine diagnostic services use this device to pinpoint mechanical issues by tuning into the internal parts' sounds. Furthermore, this tool is used for detecting leaks in scientific vacuum chambers and performing various other acoustic monitoring tasks on a small scale.
