We hear through our ears, although it is a rather complex process for us to perceive the sound.
This is the basic structure of the ear:

The ear is separated into 3 distinct sections:
[ul]
[li]The outer ear[/li]
[li]The middle ear[/li]
[li]The inner ear[/li]
[/ul]
[u]The outer ear:[/u]
Contains the outer section of the ear, including the [b]Pinna[/b] and the [b]Auditory Canal[/b].
[u]The middle ear:[/u]
Contains the middle section of the ear, including the [b]Eardrum[/b], [b]the Hammer[/b], [b]the Anvil[/b], [b]the Stirrup[/b].
[u]The inner ear:[/u]
It contains the inner section of the ear, including the [b]Cochlea[/b], and the [b]Auditory Nerve[/b], leading off from it.

[u]How they function together[/u]
The outer ear receives sound, which is then transferred through the [b]Auditory Canal[/b] (with air as the medium), into the [b]Eardrum[/b]. The [b]Eardrum[/b] vibrates and passes on the vibrations on to the [b]three small bones[/b] (otherwise called [b]ossicles[/b]) - [b]the Hammer[/b], [b]the Anvil[/b], [b]the Stirrup[/b], and then to the [b]Cochlea[/b], which converts the vibrations into electricity - which then passes it onto the [b]Auditory Nerve[/b], which relays these signals to the brain, which interprets them as what we perceive as sound.
