How do we hear?
The hearing system is consisted from two principle organs: The ear as a receiver and the brain as an interpreter of sounds. The three areas that form the ear are: The outer ear, that collects and channels sound waves from the air through the external auditory canal to the interior of the ear. The middle ear, that transmits sound waves from the outer ear to the inner ear. The inner ear, that transmits the mechanical vibrations to the brain.
Source: Hearing is a series of events in which the ear converts sound waves into electrical signals and causes nerve impulses to be sent to the brain where they are interpreted as sound. The ear has three main parts: the outer, middle, and inner ear. Sound waves enter through the outer ear and reach the middle ear, where they cause the ear drum to vibrate. The vibrations are transmitted through three tiny bones in the middle ear called the ossicles.
Hearing is a complex process involving the three major parts of the ear: the outer, the middle and the inner ear. The outer ear collects surrounding sound waves and funnels them through the ear canal down to the eardrum, the beginning of the middle ear. The sound waves cause the eardrum to vibrate. Three tiny bones attached to the eardrum convert the vibration into pressure waves and move them down to the inner ear. There the cochlea, a fluid-filled, bony maze full of minute hair cells, turns the pressure waves into electro-chemical impulses which then travel to the brain where they are interpreted as the sounds you recognize.
