Hint: it’s not just with the ear!
Did you know that it’s actually our brains that “hear” sound? While the ear plays an important role in both hearing and balance, think of it like a funnel. It helps capture sounds from the outside world and takes them to our brain for processing.
There are three main parts to the ear:
Picks up the sound from our outside environment, which turns into sound waves that vibrate down the ear canal.
This is where sound waves travel down to vibrate the ear drum, which is connected to three little bones that form what’s known as the ossicular chain. This then pushes the sound into a spiral-shaped area known as the cochlea.
Once the sound has reached the cochlea, there are many thousands of little hair cells that vibrate depending on the frequency of sound. This helps convert the sound from being an acoustic signal in our outside environment, to an electrical signal which travels up the auditory nerve pathway to our brain for processing.
