Answer 1

◆ Structure of Ear ◆


We hear sound through our ears. The ears are the sense organs which helps us in hearing sound.

The Ear consists of three components :-

→ Outer Ear
→ Middle Ear
→ Inner Ear

The part of Ear which we see outside the head is called (Outer Ear) . It consists of a broad funnel like part called (pinna) and about 2 to 3 centimeters long passage called (Ear canal). At the end of the Ear canal is a thin, elastic and circular membrane called (eardrum). The eardrum is also called (tympanum).


The Sound waves are collected by the pinna of Outer Ear. These sound waves pass through the Ear canal and fall on the eardrum. The eardrum starts vibrating back and forth rapidly.


The eardrum then sends vibrations to the middle Ear and then to the inner ear. From there, the signal goes to the brain. That is how we hear .
