In human audition, the vibration of the ossicles is triggered by the vibration of the tympanic membrane (the eardrum) and transmitted directly to the fluid and membranes of the inner ear.
The inner ear is shaped like a snail with a thousands of tiny hair cells in it and it is called the cochlea. Hair cells change the vibrations into electrical signals that are sent to the brain through the auditory nerve.
