$\underline{\underline{\huge{\textbf{Working of Human Ear :}}}}$


Sound waves travel through the external auditory canal. After striking the eardrum it produce vibration. The eardrum is connected to the hammer [three small bones of ear i.e. hammer, incus and stapes]. Then it transmit sound vibrations from hammer to incus and then to stapes....

The stapes pushes vibrations in and out against the structure called oval window... This action is passed on to the cochlea [It is a fluid filled snail like structure].

Cochlea contains Corti. It consists of small hair cells that lies in Corti. These cells transmit vibrations into electrical impulses that carry to the brain by auditory nerves... 

The brain interpret these electrical impulses and we get sensation of hearing means we hear sound....
