[The activity and capacity of the inner ear (author's transl)].

The inner ear is an energy converter and a biochemical amplifier. The normal function of the stria vascularis and the organ of Corti is bound exclusively to the respiratory metabolism. Some but not all species are equiped by a glycolytic reserve metabolism for preservation of the sensory cells, as could be improved in amplitude-time-curves of cochlea microphonics in hypoxic conditiones. A promising therapy of inner ear disturbances following short timed oxygen deficiency depends on the moment of the treatment.
