The structures of the inner ear that are displaced by sound waves are the tympanic membrane, ossicles, and the cochlea. These structures work together to convert sound waves into electrical signals for the brain to perceive as sound.
The structures of the inner ear that are displaced by incoming sound waves are the tympanic membrane, ossicles, and the cochlea. The tympanic membrane vibrates when struck by sound waves and transfers the vibrations to the three bones of the middle ear called ossicles - the malleus, incus, and stapes.
The stapes then transfers the vibrations to the cochlea where they are transduced into electrical signals that are sent to the brain.
