Ears, and the ways they work, are complex. When sound waves enter the ear, it's only just the beginning - they've got a number of complex structures to engage with before they're finally interpreted by the brain. Below, we'll talk about the sound waves' travels through the anatomy of the ear.
Once the sound wave has traveled through the ear canal, it reaches the ear drum - a thin membrane between the outer and middle ear.
The ear drum is directly connected to the human body's smallest bones - the hammer bone, anvil and stapes. These tiny bones transmit the ear drum's mechanical vibrations through to the inner ear.
Once the stapes transmits the vibrations through to the inner ear, the sound waves reach the fluid-filled cochlea.
The sound wave travels through the fluid-filled cochlea and through the hair cells, who change the mechanical vibrations into electrical nerve impulses. Those impulses are then passed to the brain, the end of their journey and the point at which we hear!
