Hearing depends on a series of complex steps that change sound waves in the air into electrical signals. Our auditory nerve then carries these signals to the brain.

How do humans hear sound ?
Answer :-
Ear is the organ in the human body that help us to hear the sound. We can classify the parts of ear as (i) outer ear (ii) middle ear and (iii) inner ear.
The outer ear consists of an ear flap or external ear called pinna and an ear Canal or the auditory Canal, which directs the sound to the ear drum. The eardrum is a stretched membrane like the skin of drum. It acts as an interface to Outer ear and the middle ear. Ear drum is also called tympanum.
Middle ear is an air filled columns with three tiny interconnected bones - incus, malleus and stapes. The inner ear has three parts - cochlea, semicircular canal and auditory nerves.
The pinna collects sound from outside and channels it to the middle ear. The bones of the middle ear vibrate and amplify the sound and transfer it to the inner ear. The parts of the inner ear have sound sensitive cells that receive the amplified vibration. This causes the specialised cells to vibrate. The vibrations are converted into nerve impulses which are carried to the Brain for interpretation.
