There are three parts of the ear that work together to pass noise from external sources through your ear to your brain for information processing. The three sections are known as; the inner ear, the middle ear, the outer ear . The inner ear is made up of the cochlea, the auditory nerve and the brain.

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.
How sound travels through the ear step by step?
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 is your inner ear called?
inner ear, also called labyrinth of the ear , part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea.
Where is the organ of hearing found?
The Inner Ear
The cochlea is a snail-shaped, bony structure that contains the sensory organ of hearing called the organ of Corti. The organ of Corti releases chemical messengers when the vibrations from the stapes activate its tiny hair cells.
What is meatus of ear?
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear . The adult human ear canal extends from the pinna to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.

Inside the cochlear duct is the main hearing organ, the spiral shaped organ of Corti.
