Question

The ear flap is shaped like a funnel suggest a reason?

Answer 1

Answer:

Explanation:

The pinna is the only visible part of the ear (the auricle) with its special helical shape. ... The function of the pinna is to act as a kind of funnel which assists in directing the sound further into the ear. Without this funnel the sound waves would take a more direct route into the auditory canal.

Answer 2

The ear flap is shaped like a funnel because -

• The sound waves come to our ear from 360 degree orientation from the environment.

• That's why our ear needs to accept sound waves from all the possible directions.

• The funnel like shape of our external ear helps in this accepting process from all the directions in a better way.

The sound waves reflect in this funnel shape from different directions and enters in our ear canal in a directed way.
