How Hearing Works
How Hearing Works
Whenever something / someone produces sound waves, it first goes into the canal of your ear, with the parts of the outer ear guiding it into there. Then, it hits your eardrum which vibrates your malleus, sending a reaction through the stapes and incus and into your cochlea. Then, the cochlea sends signals through thousands of bundles of hairs, which each pick up a different pitch depending on where it is inside the cochlea. After that, the hairs create electrical signals, which they send through the auditory nerve, into your brain. Finally, your brain registers it, and that is how you hear sound.
The Outer Ear
The outer ear is the visible part of your ear. It collects sound waves using the pinna, then stems them into the canal of your ear, where after that the sound is amplified by your middle ear.Â
The Middle Ear
After being channeled into the middle ear by your outer ear, the sound waves hit your eardrum which then starts up the different parts of your middle ear. When the eardrum vibrates, the bones in your ear pick up the vibrations, move, and sends the sound waves into your inner ear.
The Inner Ear
Finally, the vibrations are sent into your cochlea, which then vibrate the thousands of bundles of hair stuck to the walls, sending an electric signal through the auditory nerve, into your brain, which last but not least interprets the electric signal into sound.
