6How do we hear?#1 OuterEar#1) The outer ear consists of the ear canal and eardrum. Sound travels down theear canal, striking the eardrum and causing it to move or vibrate.
7How do we hear?#2 Middle Ear#2) The middle ear contains three small bones called ossicles. This chain of tiny bones is connected to the eardrum at one end and to an opening to the inner ear at the other end. Vibrations from the eardrum cause the ossicles to vibrate which, in turn, creates movement of the fluid in the inner ear.
8How do we hear?#3 Inner Ear(Cochlea)#3) The movement of the fluid in the inner ear or cochlea, causes changes in tiny structures called hair cells.
9How do we hear?#4 AuditoryNerve#4) This movement of the hair cells sends electric signals from the inner ear up the auditory nerve (also known as the hearing nerve) to the brain.
10How do we hear?#5 Brain#5) The brain then interprets these electrical signals as sound.
11SummaryBecoming educated about the ear and how we hear is the first step towards advocating.Knowing the anatomy of the ear helps us to better understand how we hear.Understanding how hearing is processed enables us to educate those who have hearing loss.
