How The Ear Works Animation For Kids

Hearing is how we perceive sound. It's how our ears accept sound waves and plough them into something our brain tin can understand.

In that location are three major parts of the ear that assist us to hear:

1. The outer ear - The outer ear has three sections:
   • The pinna or auricle: this is the part of the ear on the outside of our heads. The part nosotros unremarkably are referring to when we say ear. It helps to gather sound and vibrations then we tin hear more sounds.
   • The ear canal: This is a tube that helps sound to travel further inside our ear and to get to the next stage of hearing
   • The eardrum: The eardrum is a thin sheet that vibrates when the sound hits it. Your eardrum is very sensitive and fragile. It's never a good idea to put anything in your ear, even something that seems safe and soft tin damage your eardrum.
2. The heart ear - The middle ear is filled mostly with air and has three bones in it. That's correct your ear has little bones chosen ossicles that help yous hear! They are called the hammer (malleus), anvil (incus), and stirrup (stapes). They amplify the sound or make it louder. The middle ear helps to transfer sounds from the air to fluid inside the next stage, or inner ear. The stirrup is the smallest bone in the body.
3. The inner ear - The inner ear is filled with fluid and has the hearing organ called the cochlea. This organ helps to take the vibrations and translate them into electric signals for the nerve to transport to the brain. It actually uses little hairs that vibrate with the audio waves in the fluid. Then you lot "hear" information technology. Astonishing! The inner ear also has fluid filled tubes that assist with your residual.

Why two ears?

Having two ears helps y'all to make up one's mind the management of sound. Your brain is smart enough to figure out that if sound hits ane ear just before the other and is slightly louder then that'due south the direction the sound came from. Having an ear on each side of our head besides helps us to hear better.

The Frequency of Sound

We can hear sound within a certain frequency range of around 20 Hz on the low end and 20,000 Hz on the high end. Some animals accept different ranges. Dolphins, for example, tin can't hear sounds as low equally we can, merely can hear high sounds of over 100,000 Hz. Dogs and cats tin hear much higher pitched sounds than we can.

Why do I get giddy?

The brain takes in a number of signals from your torso to continue information technology balanced. One of them is from the fluid in the inner ear. The encephalon tin tell a lot by how the fluid in your ear is moving or tilted. The encephalon likewise uses your eyes and sense of touch on to tell information technology about your balance and position. When you spin actually fast and so finish, the fluid in your ear is even so spinning, but your optics and body have stopped moving. Your encephalon gets dislocated for a chip and you feel silly.
