The Mechanism of Bone Conduction: An experimental study

In 58 cats measurements were carried out to obtain a more profound insight into the importance of the external auditory canal, the middle and inner ear constructions in connection with bone conduction. It was found that the inertia of the ossicular chain as well as that of the inner ear fluid are by far the most important components causing bone conduction and that the mobile system of the ear must be considered to consist of at least two loosely coupled units of vibration.
