Tympanic membrane buckling doubles the force delivered to the middle ear bones.

Evidence

Pickles (1982) describes a third aspect of the middle ear that appears relevant to the impedance conversion process. This relates to a buckling motion of the tympanic membrane itself as it moves, resulting in a twofold increase in the force applied to the malleus. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 536
