O. Borysenko Effect of the Mastoid Cavity and External Auditory Canal Volume Changes in Sound Transmission
The main function of the middle ear is well-known. It serves as a mechanical transformer, designed for transmission of acoustic energy from the external air to the cochlea fluids. In the absence of such energy transformer of the vibrational motion of air particles will be reflected at the on the border with the labyrinth fluid. The appearance of the corresponding mechanical amplification leads ...
