Which instrument is used for listening to sounds produced within the body?

• A. Stethoscope
• B. Thermometer
• C. Otoscope
• D. Sphygmomanometer

Answer: (A)

Listening to internal body sounds is done with a stethoscope. It’s designed for auscultation, letting a clinician hear heartbeats, breath sounds, and other internal noises by transmitting them from the chest or back through the earpieces. The chest piece usually has a diaphragm for higher-pitched sounds and a bell for lower-pitched ones. This tool helps detect normal rhythms and potential problems like heart murmurs or wheezes. Other items serve different purposes: a thermometer measures temperature, an otoscope examines the ears, and a sphygmomanometer measures blood pressure. So for listening to sounds produced within the body, the stethoscope is the instrument used.
