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: [img src='https://res.cloudinary.com/deylrqt2d/image/upload/v1488049068/large_1_nwjv6j.png' style='width:30vw'] 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. [highlight] [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.
