The eardrum is a thin flap of skin that is stretched tight like a drum and vibrates when sound hits it. These vibrations move the tiny bones of the middle ear, which send vibrations to the inner ear.

How do we hear sound BYJU's?

The inner ear is also termed as the cochlea. There are a numerous number of tiny hair cells present inside the cochlea. These hair cells convert the vibrations into electrical signals which are then transferred to the brain through the auditory nerve. This is how we detect sound or noise.
