How the ear works step by step?
How the ear works step by step?
Here are 6 basic steps to how we hear:
- Sound transfers into the ear canal and causes the eardrum to move.
- The eardrum will vibrate with vibrates with the different sounds.
- These sound vibrations make their way through the ossicles to the cochlea.
- Sound vibrations make the fluid in the cochlea travel like ocean waves.
What part of the ear is used for hearing?
Your inner ear helps with both hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals are part of your balance system. The cochlea is bony and looks like a snail.

What is the correct path of sound through the ear to the brain?
The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to the brain.
Why is the ear shaped like it is?
The outer ear’s shape helps to collect sound and direct it inside the head toward the middle and inner ears. Along the way, the shape of the ear helps to amplify the sound — or increase its volume — and determine where it’s coming from. From the outer ear, sound waves travel through a tube called the ear canal.
What causes hearing loss?
Aging and exposure to loud noise may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When these hairs or nerve cells are damaged or missing, electrical signals aren’t transmitted as efficiently, and hearing loss occurs.
How does sound travel in the ear?
Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate. The eardrum is connected to the malleus, one of three small bones of the middle ear. Also called the hammer, it transmits sound vibrations to the incus, which passes them to the stapes
What is the function of ear?
The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells.
What is earwax produced by?
Earwax is produced by the ear to clean and protect itself. It’s secreted by glands in the skin that line the outer half of your ear canals. The wax and tiny hairs in these passages trap dust and other foreign particles that could damage deeper structures, such as your eardrum
Where is wax in the ear?
Earwax is made in the outer ear canal. This is the area between the fleshy part of the ear on the outside of your head (the part you can see) and the middle ear. The skin in the outer ear canal has special glands that produce earwax. The fancy name for this waxy stuff is cerumen (say: suh-ROO-mun).
