Question

Which of the following parts acts as a passage for the sound waves into the ear?

  1. Ear lobe
  2. Ear canal
  3. Ear pinna
  4. Hammer bone

hintHint:

Ear canal

The correct answer is: Ear canal


    • Ear canal acts as a passage for the sound waves into the ear.
    • It connects the pinna and the ear drum.
    • It is a part of the outer ear.
    • So, the correct option is b.
