Answer 2

Answer:

Stethoscope, medical instrument used in listening to sounds produced within the body, chiefly in the heart or lungs. It was invented by the French physician R.T.H. Laënnec, who in 1819 described the use of a perforated wooden cylinder to transmit sounds from the patient’s chest (Greek: stēthos) to the physician’s ear. This monaural stethoscope was modified to more convenient forms, but it has been largely supplanted by the binaural type with two flexible rubber tubes attaching the chest piece to spring-connected metal tubes with earpieces.
