Q. Which of these parts of the ear responds to sound waves like a microphone’s diaphragm?
✅ Correct Answer: (A)
eardrum
Explanation: When a compression of the medium reaches the eardrum the pressure on the outside of the membrane increases and forces the eardrum inward. Similarly, the eardrum moves outward when a rarefaction reaches it. In this way the eardrum vibrates.
