The correct pathway for sound waves to reach the brain is: Auditory canal → tympanic membrane (eardrum) → ossicles (malleus, incus, stapes) → oval window → cochlear duct (within the cochlea) → spiral organ (organ of Corti, where sound waves are converted into electrical signals) → fibers of cochlear nerve (which carry the signals to the brain).
