Sound waves travel through the air and enter our ears. Inside the ear, these sound waves cause the eardrum to vibrate. The vibrations are then transmitted through the auditory ossicles in the middle ear to the cochlea in the inner ear. The cochlea converts these vibrations into electrical signals, which are then interpreted by the brain as sound.

Sound waves enter the outer ear and travel through the ear canal, causing the eardrum to vibrate. These vibrations are transmitted through the middle ear bones (ossicles) to the cochlea in the inner ear. Inside the cochlea, specialized hair cells convert the vibrations into electrical signals, which are then sent via the auditory nerve to the brain, where they are interpreted as sound.
