How Does Sound Travel Through The Ear To The Brain?

How the ear works step by step?

Here are 6 basic steps to how we hear: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.

How does the brain process sound?

The brain translates impulses from the ear into sounds that we know and understand. The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the brain as sound.

Can you get to the brain through the ear?

The vibrations from the middle ear change into nerve signals in the inner ear. The inner ear includes the cochlea (say: KOH-klee-uh) and the semicircular canals. These signals travel to the brain along the cochlear nerve, also known as the auditory nerve. The semicircular canals look like three tiny connected tubes.

How do we perceive sound?

  • Hearing, or auditory perception, is the ability to perceive sounds by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear.
  • Sound may be heard through solid, liquid, or gaseous matter.
