Answer:
Explanation:
Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear.
Inside the cochlea, there are thousands of tiny hair cells. Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve. The brain tells you that you are hearing a sound and what that sound .

Question :
How do we hear sound, explain.
Answer:
We hear sound due to hitting or rubbing or friction. Sound wave is created from any source due to vibration of its particles. The sound wave gets dispersed to air and travel through the medium by the process of compression and refraction.
When the sound wave reaches to our ear then it passes through the ear canal. Then it causes disturbance to the ear-wax and finally creates vibration to the pinna or to the bones of the ear. Then it hits to the cochlea and disturbs the fluid inside the cochlea. And finally due to vibration the sound of reaches to the ear-drum and strikes on it. As a result we hear the sound.
