Extra for Experts: Research and then write in you own words how do we hear sound? How do sound waves get from our ear to our brain?
How do we hear sound?
Sound waves travel into the ear canal until they reach the eardrum. The eardrum passes the vibrations through the middle ear bones into the inner ear.
How do sound waves get from our ear to our brain?
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
Movement of fluid in turn makes the hair cells 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.
The auditory nerve moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”.
