The ear consists of three compartments, outer ear, middle ear and inner ear. The part of ear which we see outside the head is called outer ear. The part of the outer ear that is visible to us is called pinna. The pinna collects sound waves and directs them to the ear tube

Answer 2

Answer:

Sound waves are not to be collected and directs them to eartube. Sound wave propagate in medium (air) and thus reaches to our ear at their own.

As it reaches close to the ear our ear pinna collect and direct them to inner ear tube.
