Question

why are we able to hear with our ears ?​

Answer 1

Answer:

Here's Your Answer

Explanation:

●Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum.

●The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.

●These bones are called the malleus, incus, and stapes.

Answer 2

Answer:

hello friend.

I explain answer step by step.

here I consider important points.

step by step explanation:

$\huge \red \star \: outer \: ear$

Your outer ear includes your pinna and ear canal. The pinna is the part of your ear that you see on the sides of your head. Sounds go into the pinna and down your ear canal.

.

$\huge \star \: middle\: ear$

Your eardrum is at the end of your ear canal. This is where your middle ear starts. Your middle ear has three tiny bones in it. These three bones form a chain from the eardrum to the inner ear. The eardrum moves back and forth when sounds hit it. The eardrum makes the small bones move. This movement sends a signal to the inner ear.

.

$\huge \star \ inner \: ear$

Your inner ear helps with both hearing and balance. The cochlea is the hearing part of the inner ear.

The cochlea is bony and looks like a snail. It has fluid and hair cells inside of it. When the bones in your middle ear move, the fluid in your inner ear starts to move. This movement triggers the hair cells. Not all hair cells move at the same time. Different hair cells move for different sounds.

The hair cells change the movement into electrical signals. These signals go through your auditory nerve into your brain. Your brain understands these electrical signals as sounds. Your brain then has to figure out what the sounds mean and how to respond. This is how we hear.
