[Physiology of bone conduction acoustic stimulation and the importance of high-frequency bone conduction].

The phenomenon of bone-conducted sound transmission involves more than just vibration of the skull bones to induce movement of the labyrinthine fluid. This mechanical energy is known to be distributed through the outer, middle and inner ear and identifying the precise contribution of each of these parts to total conductance is difficult. Cochlear fluid inertia is the most important contributing factor to bone-conduction hearing, inertia of the ossicles plays a role in medium-frequency conduction, while cochlear wall compression plays a role in high frequencies.
