The ability to accurately identify sound is possible due to the auditory system..
00:00:00
..that is comprised of your ears and the brain.
00:00:07
The ear's job is to convert the sound energy into a neutral signal..
00:00:10
..which later is received by your brain through three parts of the ear.
00:00:16
The outer ear, the middle ear and the inner ear.
00:00:21
But the big question is, how does it work?
00:00:26
Well, it all starts with the sound waves falling on the outer part of your ear known as the pinna
00:00:30
that acts as a funnel and sends the sound into the ear canal, another part of your outer ear
00:00:38
and heads towards the middle part of your ear hitting the eardrum, a very delicate piece of tightly stretched skin
00:00:46
making it vibrate like the head of an actual drum.
00:00:56
This vibrating eardrum shakes a tiny chain of three bones called the ossicle..
00:01:00
..that starts with a hammer and passes through the angle..
00:01:07
..and moves the third bone known as tapes or stirrup.
00:01:11
But it's not over yet.
00:01:17
Once the sound passes the middle ear through the ossicle..
00:01:19
..it travels into the cochlea, a small circular tube..
00:01:24
Filled with liquid situated in the inner ear.
00:01:28
The cochlea consists of many hair.
00:01:33
And when the fluid in the cochlea moves, it moves these tiny hair.
00:01:36
Creating nerve signals that get sent through the auditory nerve into the brain.
00:01:41
The brain processes these signals as sound and so you hear.
00:01:47
Also, not all living creatures hear with ears.
00:01:54
ears, snakes use jaw bones, fish respond to pressure changes and male mosquitoes use antenna.
