00:00Oh! Did you hear that, friends? I think someone needs help.
00:05Let's follow the sound and find out.
00:17Oh no, little kitty! Say thanks to my sharp ears.
00:21They are the reason why I am able to hear so clearly.
00:25Oh no, little kitty! Say thanks to my sharp ears..
00:30..that were able to detect your squeaky voice..
00:33..despite loud music playing in the background.
00:36Speaking of ears, have you ever wondered..
00:39..how you could hear what I say and all the noise around you?
00:43Don't worry if you have not, because I am here to explain.
00:49So, zoom in!
00:52The ability to accurately identify sound is possible..
00:57..due to the auditory system that is comprised of your ears and the brain.
01:02The ear's job is to convert the sound energy into a neutral signal..
01:07..which later is received by your brain through three parts of the ear.
01:12The outer ear, the middle ear and the inner ear.
01:18But the big question is, how does it work?
01:24Well, it all starts with the sound waves falling on the outer part of your ear..
01:29..known as the pinna, that acts as a funnel..
01:33..and sends the sound into the ear canal, another part of your outer ear.
01:39And heads towards the middle part of your ear, hitting the ear drum..
01:45..a very delicate piece of tightly stretched skin..
01:48..making it vibrate like the head of an actual drum.
01:52This vibrating ear drum shakes a tiny chain of three bones called the ossicle..
01:59..that starts with a hammer and passes through the anvil..
02:03..and moves the third bone known as tapes or stirrup.
02:09But it's not over yet.
02:12Once the sound passes the middle ear through the ossicle..
02:16..it travels into the cochlea, a small circular tube..
02:20..filled with liquid situated in the inner ear.
02:24The vibration caused by the ossicles create waves in the cochlea fluid..
02:30..converting the sound vibration into liquid vibration.
02:36The cochlea consists of many hair.
02:39And when the fluid in the cochlea moves, it moves these tiny hair..
02:45..creating nerve signals that get sent through the auditory nerve into the brain.
02:50The brain processes these signals as sound and so you hear.
02:56It's Trivia Time!
02:58Did you know that cochlea means snail in Latin?
03:02The cochlea gets its name from its unique coiled up shape..
03:07..that looks like a snail's shell.
03:09I bet that was the first thing that came to your mind when you saw it.
03:15Also, not all living creatures hear with ears.
03:18Snakes use jaw bones, fish respond to pressure changes..
03:24..and male mosquitoes use antenna.
03:28It's Question Time!
