+'''Hearing''' is the ability to perceive [[sound]] by detecting vibrations through an organ such as the [[ear]]. It is one of the major senses of humans and many animals. Hearing is crucial for [[communication]], [[learning]], and [[navigation]].

+Hearing involves the complex process of sound wave propagation, which is captured by the ear and converted into electrical signals that are interpreted by the [[brain]]. The primary components of the auditory system include the outer ear, middle ear, inner ear, and the auditory pathways in the brain.

== Human ear ==
In [[humans]]s, sound travels through three main parts of the ear to be heard. These are the outer, middle and inner ear.
*Outer Ear - This is the part of the ear that we can see called the [[pinna]] as well as the inside of the ear called the [[ear canal]]. Sound first travels through the pinna and ear canal then to the [[eardrum]] at the end of the canal which the sound makes vibrate.
*Middle Ear - Sound continues to travel deeper into the ear and is helped by three of the smallest bones in the body - hammer, anvil and stirrup - to reach the inner ear.
*[[Inner ear|Inner Ear]] - Here the sound reaches a small tube shaped like a snail shell, called the ''[[cochlea]]''. Inside the cochlea is a fluid, which moves tiny hairs that send signals to the brain which interprets sounds for you to understand and hear

== How does hearing work? ==
* The outer ear collects sound waves and works like a funnel to send them through a narrow tube (ear canal) that leads inside the ear.
* At the end of the ear canal is the ear drum (tympanic membrane).
* The tympanic membrane is a thin membrane that vibrates when sound waves strike it.
* It divides the area called the outer ear from the middle ear.
* It is attached to a set of three tiny bones in the middle ear.
* These bones are called the hammer (malleus), anvil (incus), and the stirrup (stapes).
* The bones pass the vibrations of sound waves to a small organ in the hearing part of the inner ear called the cochlea, which is a coiled structure like a snail shell.
* The inner ear is filled with a thin fluid that transmits pressure changes throughout the cochlea.
* Inside the cochlea are tiny hair cells that pick up sound vibrations from the fluid and cause nerve impulses in the auditory nerve.
* The auditory nerve carries the message to the brain, where it is interpreted as sound
