The three ossicles (little bones) of the middle ear amplify sound in two ways:
- the size of the eardrum is different from the stapes/stirrup. The concentration of the vibration from the large eardrum to the small stapes, the pressure is much greater. This is called hydraulic multiplication.
- The size of each ossicle is another factor. The malleus/hammer is longer than the incus. the malleus moves a greater distance, and the incus moves with greater force (E = force x distance).
