In the sound conduction system of the outer and middle ear, the sound wave is retained in its original type; the vibrations are simply amplified and passed on. When the sound wave is introduced into the sound perception system of the inner ear, a mechanical transformation into a traveling wave takes place, which the receptor cells then transform into electric nerve impulses.

Information and ideas:
Here the question can be raised as to what extent a weakening or interruption of this system leads to a reduction of hearing ability.
