Respuesta :

We hear sound because of sound waves.

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:

Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones or ossicles into the inner ear. The inner ear is shaped like a snail and is also called the cochlea.

Explanation:

Here are 6 basic steps to how we hear:

1.Sound transfers into the ear canal and causes the eardrum to move

2.The eardrum will vibrate with vibrates with the different sounds

3.These sound vibrations make their way through the ossicles to the cochlea

4.Sound vibrations make the fluid in the cochlea travel like ocean waves. Movement of fluid in turn makes the hair cells

5.The auditory nerve picks up any neural signals created by the hair cells. Hair cells at one end of the cochlea transfer low pitch sound information and hair cells at the opposite end transfer high pitch sound information.

6.The auditory nerve moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”.
