Question 6
HThe Figure shows a simplified diagram of the human ear.
Figure
a.[3]
Name the parts labelled A, B and C.
b.[4]
Explain how the ear converts a sound wave in air into vibrations in solids and then detects them.
c.[2]
Some people have a condition in which the parts labelled B become stiff and cannot move easily.
Suggest how this affects their hearing. Explain your answer.
