Answer: A stethoscope is used to listen to internal sounds within a body. The act of listening is called auscultation. A medical professional is the most likely user. This trained user can assess cardiac and respiratory functions when correctly using the simple device. And in addition to this, arterial and venus flow can be heard and so can intestinal activity, among other things.The stethoscope finds limited use with mechanics, though a long screwdriver pressed to an engine part with the handle pressed to the ear works pretty well. Some other applications may present themselves with a bit of thought and consideration. Links can be found below.
Answer: A stethoscope is a medical device used to hear sounds from within the body. It consists of a cup-like "chestpiece" connected by air-filled rubber tubing to two earpieces. The effect is to isolate and magnify the sounds from the internal organs (heart, lungs, blood vessels). The stethoscope can listen for changes in heart contractions, or breathing, or blood flow (often used to detect a pulse when determining the rate of a heart beat).
