How Ear Works? | The Process Of Hearing (3D Animation)
Do you know how we are able to hear any sound through our ears? Let's see how our ears work. Our ear is divided into three parts:
1) Outer Ear
2) Middle Ear
3) Inner Ear
Whenever sound vibrations are generated, they first enter our outer ear in the form of waves. At the end part of our outer ear, there is an eardrum present. When these waves collide with the eardrum, the eardrum starts to vibrate. The vibration of the eardrum sends the sound signal into the middle ear.
In the middle ear, there are three small bones present. These bones are called Malleus, Incus, and Stapes, and collectively these bones are called ossicles. These bones move with the vibrations of the eardrum and transmit the sound signal to the inner ear.
The inner ear contains a fluid-filled chamber called the cochlea, which looks like a snail's shell. Inside this chamber, along with the fluid, there are tiny hair cells present. These hair cells have hair-like projections on their surface called stereocilia.
When the bones in the middle ear amplify the sound signal and send it to the cochlea, the fluid inside the cochlea starts to move. The movement of the fluid causes the stereocilia to move, which sends the sound signal through the cochlear, also known as the auditory nerve.
From the auditory nerve, this sound signal reaches the brain in the form of electrical impulses, and then the brain processes the signal to determine which sound has reached it.
Apart from all this, our ears also help in maintaining the balance of our body, which we will discuss in another video. For today, that's all. Until next time, goodbye and thank you.
