The eardrum is a thin skin that can be stretch like a drum and vibrates when it hears a sound. The vibrations move tiny bones to the middle ear that sends a vibration to the inner ear.The three small bones in the middle (ossicles) conduct a sound vibration from our eardrum to the inner ear.The footplate pushed the oval window membrane to set the cochlea fluid to move in motion.The cochlea moves in response to the vibrations from the oval window.

The eardrum is a membrane located at the end of the auditory canal, separating the outer ear and middle ear. The middle ear contains three small bones that transmit vibrations coming from the eardrum to the cochlea. The cochlea is a tube in the inner ear which is filled with fluid. Vibrations entering the cochlea from the middle ear cause the fluid inside the cochlea to vibrate, thus stimulating the hair cells.Result:Before reaching the hair cells, sound waves are transmitted through several parts of the ear, including the eardrum, the middle ear, and the cochlea.
