Explanation:
· A
Stethoscope is a medical device used to listen to the internal sounds of an animal or human body, a practice known as
auscultation.
· It is primarily used to listen to the sounds of the
heart,
lungs, and intestines, allowing doctors to detect abnormal rhythms, breathing patterns, or blockages.
· The instrument works by amplifying the internal sounds through a chest piece, tubes, and earpieces.
Information Booster:
· The stethoscope was invented in 1816 by French physician
René Laennec.
· The modern stethoscope design was pioneered by David Littmann in the 1960s, leading to higher acoustic quality.
· A
digital stethoscope can convert acoustic sounds into electronic signals, which can then be amplified, recorded, or filtered.
