The Hearing Process

The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane that separates the outer ear from the middle ear. Its main function is to vibrate in response to sound waves, which helps to transmit sound from the outer ear to the middle ear.

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear. It plays a crucial role in the process of hearing by converting sound vibrations into electrical signals. These signals are then transmitted to the brain through the auditory nerve, allowing us to perceive and interpret sound.

When sound waves enter the ear canal, they cause the eardrum to vibrate. These vibrations are then transmitted through the middle ear bones (ossicles) to the cochlea in the inner ear. The cochlea converts these vibrations into electrical signals that are sent to the brain via the auditory nerve, allowing us to perceive sound.
