3BHow Your Hearing Works 37
The scala tympani , the scala vestibuli , and the scala media are the tubes in the inner ear , and they are curved together into a shape that appears like the shell of a snail . These tubes are separated by extremely thin membranes that move the sound along the tubes , and move the pressure that is created when the stapes moves against the cochlea as a whole . The basilar membrane is made up of tiny hair cells – there are tens of thousands of them , which react to differing frequencies in the sound that is being pushed through the cochlea . The hair cells identify resonant frequencies in the sound waves that are transferred through the cochlea . These create electrical impulses that are transported to the brain and interpreted as recognizable sounds .
Scientists are still working on a thorough understanding of just how the brain is able to interpret these electrical pulses into language , music , or just plain noise . The ear is a complicated and sophisticated system , which takes an external stimulus and uses mechanical energy to transfer that information to the brain . As we learn more and more about how we hear and what we hear , the ear appears even more remarkable !
