Hey guys, whats up? How are you doing? Oh, cool. I really don't care...hah.... How am I? Well, my ears are KILLING me! We were just listening to some high frequencies that only kids can hear and it has something to do with our upcoming topic! So today we will be taking about your ears and what goes on inside them. Well, lets get started!
The ear is divided up into three parts, the outer ear, the middle ear, and the inner ear. The outer ear is the only part you can see and it is made up of cartlage. You also have these ridges which make the sound waves smaller and go into your inner ear.
The middle ear contains the stirrup, anvil, eardrum and hammer. The stirrup, anvil, and hammer just so happen to be the three smallest bones in your entire body! Isn't that cool? Also all the action happens here. The sound (a vibrational disturbance in the air) travels into your ear and hits the eardrum. This acts like an actual drum and vibrates rapidly. The vibrations make the hammer move very quickly also and it hits the anvil. The anvil then sends out the signals or vibrations, or whatever you wanna call them, to these tiny nerve fibers and they get tickled and send a signal vibration wave thing to our brain. Then our brain determines what sound it is and how we reconize it.
Now to the inner ear... So the inner ear is where these tiny little nerve fibers are located. The process i said above it may seem complicated and long but it only takes about .01 of a second for it to work!
Okay, so next I will be going over Sign Language. What do you think it would be like to be deaf? To not be able to listen to your friends conversations and listen to your favorite music? Well, I don't know about you but my life would be pretty awful. That's why I think about how my friend Celine (not at Shriner) deals with all of that. Her whole family is deaf. Her mom, dad, step-mom, step-dad, dog, and if i am not mistaken her brother too. There are many ways to go deaf but i will only name a few. You can burst your eardrum from high music etc. It can be heredity, and you can just get to many ear infections and it can cause perminate hearing loss. It must be pretty hard for her not to just talk to her mom one-on-one without using her hands. Kuddos to you Celine!
So this is what the alphabet looks like in Sign Language. It's actually not as complicated as it might look like to learn. I learned it in 6th grade just from watching a movie! You can try it if you want, its fun! This is not how deaf people talk to each other they actually have hand motions for words and phrases! I will post a video below. We'll that's all for this blog. See you guys next time! TTYL (:
