Sound waves travel from the pinna through the ear canal to the cochlea where they are converted into electrical impulses for the brain.
The sound wave starts its journey from the pinna which collects and focuses the sound. It then travels through the ear canal to reach the tympanic membrane (eardrum) where vibrations are created. The vibrations are transmitted through the ossicles in the middle ear to the cochlea, containing auditory hair cells that convert the vibrations into electrical impulses that travel to the brain.
